Handheld Laser Welder – The Absolute FAQ Guide

Many of you might wonder what a handheld laser welder is. Though the product is self-explanatory, it’s not something many people know about.

Understanding it is easy, and upon knowing what it is – you might find yourself wanting it, too. That’s what we’ll be discussing today.

We’ll talk about handheld laser welding machines. In addition to that, we’ll also help you figure out which the best manufacturer is that you can trust!

 What is a Handheld Laser Welding Machine?

FUN FACT: Laser is short for “Light Amplification by Stimulated Emission of Radiation.”

What is a Handheld Laser Welder
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
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.

Handheld Laser Cutter
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.

What Do You Use Laser Welding For
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:

  • Automotive Industry
  • Aerospace Industry
  • 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.

Keyhole Welding

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.

How Do Laser Welders Work
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.

What is Fiber Laser Welding
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.

  1. The first step is to turn the engine on. Make sure that you connect it with the appropriate voltage required by the machine
  2. Activate the emergency stop button, as well as the laser generator button. This will turn the screen or the interface on
  3. Activate the laser source and the water cooler/chiller
  4. Specify the power, mode, and the speed using the interface depending on the thickness of the material
  5. Grab the laser welder and adjust the focal length of the nozzle
  6. 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 Handheld Fiber Laser Welders?

It’s a type of welding machine that utilizes optical fibers.

Since it’s handheld, it’s not going to be a challenge for you to transport it from one location to another.

Is There a Laser Welding Machine for Stainless Steel?

Laser welding, in itself, is a type of procedure you can use for semi-conductive and conductive materials.

Laser Welding Machine for Stainless Steel

These handheld laser welder suppliers don’t have lucrative rates. However, they might not meet the expectations you have when it comes to features and functionality.

Since they offer entry-level laser welding equipment, you might not be able to receive some of the qualities you’re looking for.

Usual Handheld Laser Welding Machine Price

When you perform a search online, you’ll encounter a lot of varying prices about handheld laser welders.

Some machines are priced under $1,000 – but some that can go as high as $50,000.

You’ll confuse yourself when you look online. If you want real results and answers, it’s best to contact a manufacturer and ask about the rates of their equipment.

Different manufacturers offer different prices. There can’t be a median rate for them. To sketch up a rough idea on how much it costs, moderate machines would be about $8,000 to $15,000.

High-tech and advanced handheld laser welding machines would have rates upwards of $15,000 but lower than $25,000.

Parts of a Handheld Laser Welder

In order for you to fully understand a handheld laser welder, you need to know its parts.

Before purchasing yours, make sure that they have all of these parts. Missing one of these can give you bad results; and can even disrupt or mess up your projects.

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.

Better Control

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.

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 a Laser Welding Use filler?

Source Indiamart

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?

Source Collisionmastersnc

What is the Two Process of  Laser Welding?

Source Safe-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?

Source Engineering

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?

Source Thefabricator

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.

Laser Welding and It’s Benefits

Creating Complicated Joints

You can weld various materials and areas that would be too hard to reach using more conventional welding techniques with laser welding technology. Laser technology can handle difficult joints.

Precision

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.

Low Heat

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.

High Strength

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.

Consistent

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 –

  1. Pulsed laser
  2. Continuous laser

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.

  1. Manual
  2. Semi-automatic and
  3. Automatic

However, your configuration choice will depend on your demand, whether small or huge and your workstation’s setup.

Manual

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.

Semi-Automatic Laser

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.

Automatic Laser

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 –

Plates

Four types of welding processes are available.

  1. Butt welding
  2. End welding
  3. Central penetration melting welding
  4. 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 –

  1. Wire to wire butt welding
  2. Cross welding
  3. Parallel lap welding
  4. T-shaped 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.
