Handheld Laser Welding Machines – The Complete FAQ Guide
Do you believe that robotic arm welders are better than handheld laser welding machines? That’s what we’ll be finding out in this guide!
Not only will you learn about these equipment, we’ll also educate you in terms of working with the best handheld laser welding machine manufacturers in the industry!
Without further ado – let’s get onto it!
What is a Handheld Laser Welding Machine?
FUN FACT: Laser is short for “Light Amplification by Stimulated Emission of Radiation.”
Worker using handheld laser welder to weld on the workpiece
Its title pretty much tells you what it is.
Handheld laser welders are machines that can help you with laser welding and are portable. They’re light, and all electronics fit in just a single frame that’s easy to carry around.
Basics of Laser Welding
Understanding laser welding is as easy as how you understand general and basic welding.
Laser welding/cutting using an automatic welder
Firstly, laser welding is a process of joining or fusing two (2) or more pieces of metal.
The process involves a light laser beam that is highly focused and is applied to a workpiece. In the process, the heat that’s generated by the laser is what makes the welding possible.
You can make laser welding work in two (2) ways: keyhole welding and conduction limited welding; we’ll go deeper into that a bit later.
Laser Cutting vs. Laser Welding
While you’ll be able to achieve both processes using a single machine, they’re different processes.
A laser welding machine cutting a piece of a workpiece
Laser cutting is when you want to achieve a cut or a slice through a conductive material. It can be any type of conductive material.
In laser cutting, the laser beam is meant to go at the deepest, slicing or cutting through the workpiece.
Laser welding, on the other hand, is a welding process in which its goal is to connect or link various workpieces together.
What Do You Use Laser Welding For?
Because the heat source from laser welding is stronger, it can help you create stronger and more reliable seams at higher speeds.
Laser cutting/welding a part of a car or an automotive vehicle
A lot of industries and sectors rely on it; the most common ones include:
Assembly and Fabrication Industry
Engineering and IT Sectors
Construction and Structural Industries
And Many More
Different Types of Laser Welding
Remember conduction welding and keyhole welding? – They’re the types of laser welding you can perform to accomplish the welding and the cutting you need.
This process involves the heating of the workpiece or the metal in a way that vaporization of the contact surface occurs.
Thus, creating a keyhole that has a plasma-like condition with temperatures that go upwards of 10,000 Kelvin.
You’ll be able to achieve keyhole welding if you utilize high-powered lasers that go upwards of 105 W per mm2.
Conduction Limited Welding
Conduction welding is a procedure that involves heating the metal just above its melting point. As opposed to keyhole welding, you don’t need the contact surface to vaporize.
Outputs of conduction limited welding would lie between medium to moderate weld strength. A key benefit of this type of welding is the smoothness and the aesthetic appeal of the final weld.
How Do Laser Welders Work?
The principle of laser welders and welding torches is simple: the laser beam will be the agent used to heat the surface of the materials that you would fuse and join together.
Image of how a laser welds through objects and materials
Laser welders accomplish this by utilizing a pulse of light that has a small area of focus. The surface of the workpiece absorbs this, creating the heat.
How Strong Can Handheld Laser Welders Be?
Handheld laser welders deal with light, therefore, we calculate its strength via the speed of how the light travels.
Oftentimes, laser welding machines provide speeds that can be up to three (3) to five (5) times faster than MIG welding; this means five (5), even ten (10) times faster than traditional and regular TIG welding.
If it’s strength you’re worried about, you wouldn’t be dismayed with handheld laser welders.
What is Fiber Laser Welding?
Fiber laser welding is just one of the multiple laser processes.
A robotic arm performing fiber laser welding on a workpiece
It’s a welding process that utilizes solid-state lasers where optical fibers with decreased rare earth element levels are used as the medium.
You can understand it better as it’s the typical process you see in which laser welding is done.
How Do You Use a Handheld Laser Welder?
Using a handheld laser welder is not rocket science. It only requires you to know what you need to do, as well as the results you’ve been looking for.
The first step is to turn the engine on. Make sure that you connect it with the appropriate voltage required by the machine
Activate the emergency stop button, as well as the laser generator button. This will turn the screen or the interface on
Activate the laser source and the water cooler/chiller
Specify the power, mode, and the speed using the interface depending on the thickness of the material
Grab the laser welder and adjust the focal length of the nozzle
Test it using scrap materials to see if the specifications are right
That’s it! You now know how to use and operate a handheld laser welding machine.

What are the Advantages of Laser Welding?
Laser welding can bring you a ton of advantages. The most common ones of the bunch include:
Ultimate and Supreme Accuracy and Precision
Probably the main advantage that you can get is the accuracy of the weld. Since you’ll be able to control it manually, it’s up to your movement on how the weld will go.
Even if you are to weld small parts and components, it wouldn’t be a problem with laser welding.
Consistency in the Welds
Since you set the speed, power, and mode manually, you can expect that your welds will be consistent – even if you need to weld large volumes of workpieces.
Add the fact that you can produce your welds faster, laser welding truly is something you need to consider.
Ability to Create and Produce Complex Welds
Some welding techniques such as MIG welding and TIG welding aren’t the best for complex welds; this is because of the limited electrodes available.
That’s when laser welding goes up a notch. No matter how complicated a certain weld seems, laser welders will be able to reach them.
Stronger and More Durable Welds
Last but most definitely not the least is the fact that you can have stronger welds.
You wouldn’t need filler materials to weld it, which can provide excellent strength and durability.
Those are just some of the most sought after benefits laser welding has.
Benefits of Using Handheld Laser Welders
Now that you know the advantages of laser welding, what benefits could handheld laser welders have?
Let’s go on and discuss the perks of utilizing handheld or manual laser welding machines.
Control in terms of mode, speed, power, heat, etc., and control in the movement. You’ll be able to set it to the minimum, or the maximum depending on your preference.
Versatility of Welds
Another advantage of using handheld lasers is the fact that you can use it for a wide range of objects and materials.
In addition, you’ll be able to weld dissimilar objects and materials, too!
No Electrodes Needed
We also know that you don’t have to use any type of electrode for it. Therefore, you can expect less costs and damages on your outputs.
Easy to Focus
The laser beam you’ll use for the weld or the cut is easy to set to focus.
You’ll have optical instruments as guides for alignment, and you’ll never have to think about quality.
Other benefits include:
No protection required against vacuum or radiation
Can be focused in a small area
Can be operated at a small space
Many people choose automatic laser welding machines over handheld ones. While that’s fine, starting it manually is better since you’ll learn a lot from it, too.
Understanding Handheld Laser Welding Machines
Handheld laser welding machines is the mixture of both traditional and high-tech welding machinery.
Image of handheld laser welding machines in a manufacturing factory
It’s a type of equipment you can use to perform laser welding but is operated manually, thus the term “handheld.”
How does a Laser Welding Work?
Laser welding works just like conventional welding.
By using high density laser beam, laser welding machine sprays high temperature laser to the edges of joined metal.
The heat then creates a weld by melting the metals so they can stick to one another.
How Strong is Laser Welding?
Nowdays, laser welding machine with power ranging from hundreds of Watts to 60 kW are available on sale.
This range of power is strong enough to conduct welding process comparable to TIG and MIG Welding.
What Types of Laser are Used for Welding?
Fiber laser, YAG pulsed laser, and continuous wave laser are the three most common laser used for welding.
Fiber laser is used for variety of welding covering from electronics to automotive industry.
YAG pulsed laser is suitable for large spot weld like in transportation manufacturing.
And continuous wave laser is ideal for high speed and deep penetrating welding such as in small tool manufacturing.
What is the Difference between Laser Welding and Conventional Welding?
The difference is in the heat source.
Conventional welding, such as TIG (Tungsten Inert Gas) Welding and MIG (Metal Inert Gas) Welding, uses shielding gas to create an inert material that can heat up the metals.
Laser welding, on the other hand, uses high density laser beam to heat up the metal.
What is the Advatage of Laser Welding?
Laser welding has tons of advantages some of which include:
It can perform a welding process with high accuracy and precision.
It is capable of connecting complicated join in high speed.
There is no burr formation on the joining result.
It can perform repeatedly and consistently.
It can perform low heat application that that minimizes the distortion on the material used.
The welding result is relatively stronger.
What is the Disadvantage of Laser Welding?
The only disadvantage of laser welding is the cost.
Compared to conventional welding a laser welding machine is highly costly.
What is the Best HandheldLaser Welding Machine for Steel?
Any laser welding machine with enough power would be able to weld steel.
There is no clear record of who first used laser in wielding process.
Welding itself has been practiced by human since 2000 years ago with fire as the heat source.
After the invention of the high power laser, it is only natural that people would adopt it for welding.
The unique trait of laser is just so fit for manufacturing process especially welding.
Does aLaser Welding Use filler?
To strengthen the joint point between two metals, sometimes filler metal is used in the welding process.
The most common filler metal used is metal wire.
During the welding process, the metal wire is melted on the welding spot to add additional sticky element between the metals.
As a result, it would strengthen the bond of the metals.
Where is Laser Beam Welding Used?
Laser beam welding is commonly used in industrial areas that involves metal and plastic in the manufacturing process.
What is the Application of Laser Welding?
The application of laser welding is mainly in manufacturing industry related to metal and plastic.
Metal-based industry that applies laser welding in its manufacturing process includes shipbuilding, automobile, aerospace, fitness equipment, mechanical cabinets, elevator, kitchenware, sheet metal industry and so on.
And the plastic-based industry that applies laser welding in the manufacturing process includes toys, stationary, house tools, kitchenware industry and so on.
What is theTwo Process of Laser Welding?
The two process of laser welding are conduction limited welding and keyhole welding.
Conduction limited welding occurs when the power density is low so the beam only touches the surface of the material and do not penetrate it.
Keyhole welding is the common process conducted in laser welding.
In contrast with conduction limited welding, keyhole welding occurs when the power density is high so the beam can penetrate the material.
What is Laser Screw Welding?
Laser screw welding is a welding technique used mostly on automobile industry.
This technique is believed to be highly superior over the conventional resistance spot welding.
The high heat caused by the conventional resistance spot welding can cause the metal joint to deform or distort.
In order to avoid it, the laser has to stop at regular interval which is time consuming.
In contrast, laser screw welding technique uses the laser to weld the metal joint together in much faster speed.
It also generates so little heat.
As a result, the deformation and distortion issues together with the time consuming issues can be solved.
What is the Limitation of Laser Beam Welding?
Below are the limitations of laser beam welding:
The joints must be accurately positioned right under the beam.
Rapid cooling rate may cause cracking in some metal.
The maximum joint thickness that can be welded is limited. Welding penetration of thickness bigger than 19 mm is difficult.
High reflective and high thermal conductive materials like Al and Cu alloy may affect the stabilization of the welding spot.

One of the key advantages of laser welding is that it provides high precision and power. Laser welder can be used without loss to weld the tiny pieces.
The low heat usage of the laser welding technology minimizes part loss. It is also the chosen laser welding procedure for those who manufacture luxury manufacture, such as custom-made jewellery. Laser beams use very local power such that contact-free application is possible, which ensures that the pieces are mounted with less heat expansion.
Laser technology makes high strength welds possible for producers. Lasers offer excellent welding quality and clean processing, which makes manufacturers preferable, especially in the medical field where medical device and components are specifically safe.
Manufacturers are selecting laser welders as their preferred welding tool number one because it enables reliable and continuous welding. It is a high-speed welding strategy and far more flexible than other traditional techniques. The laser welding devices allow excellent repeatability, making it flexible for companies to reduce unit costs significantly.
Laser Welding Machine – Which Laser to Choose?
Either of the following two types of lasers can be used as a laser welding system –
The choice between one and the other depends on the thickness between the two. Consider the advantages of the two.
Advantages of Pulsed Laser
The pulse-pulls are made of sheet metal, gold-pulse chains ties, titanium pacemakers and razor blades.
Such a laser avoids melting or deformation of the metal.
Appropriate for thin and light metals.
Advantages of Continuous Laser
This is more expensive than the pulsed laser. It also decreases the cost of service.
Most effective in highly resistant metals.
Suitable for dense sections welding.
If you use a metal or component that is too small, you will experience problems. The laser can damage, melt, or deform the portion in such cases.
Welding Machine – Which Configuration to Choose?
For welding machines, there are three types of configurations.
However, your configuration choice will depend on your demand, whether small or huge and your workstation’s setup.
This requires considerable ability and skill and ease of maintenance in comparison with semi-automatic and automatic devices. The operator has to control the sequence of parts for welding. Best suited for production in small levels.
In a semi-automatic laser welding machine, the controller manually loads the pieces in the welding fixture. They are bigger than hand welding machines and have turntables. Ideal for medium and large industries.
These are the biggest laser welders. There is no human interference in these devices and so the user is relieved. The existence of a loading and unloading station reduces time and makes efficiency profits. The devices are robotically placed and handle the part under the laser automatically. Best for large-scale industries. However, it’s costly.
Laser Welding Types
The following can be classified as various laser welding processes –
Four types of welding processes are available.
Central penetration melting welding
Central piercing melting welding
Butt welding requires high-quality butt joint and is normally used for automatic welding or manual welding.
Wire to Wire
There are four different methods of manufacturing, including –
Wire to wire butt welding
Parallel lap welding
Such welding is not usually suited for automatic welding, manual welding or semi-automatic welding.
Metal Wire and Block Component
Laser welding can efficiently attach metal wires with a block element and randomly size the block element. The geometric measurements of the wire components should be taken into consideration in the welding.
Assembly and Sealing of Different Blocks
The joints of parts, such as sensors, include the seal welding and assembly welding.
Repair of Block Objects
Laser welding wire has been melted and placed on the laser surface. Generally suited for mould repair and repair of other items.
