Handheld Laser Welding Machines are becoming of interest to companies that want to improve productivity and reduce costs in the welding operation. Compared to traditional argon arc welding, laser welding offers significant advantages such as ease of use, lightweight design, and superior welding quality. Laser welding is more accessible and affordable than ever — offering much faster travel speeds than other welding processes and weld consistency in automated welding applications. Because skilled welders are harder to find and keep, handheld laser welding offers a practical and cost effective welding solution. Individuals with no previous welding experience can easily be trained to operate and produce welds that otherwise could have taken years to train in the tig welding and mig welding processes.

Understanding Handheld Laser Welding

What is Laser Welding?

Laser welding is a precise and efficient welding process that uses a focused laser beam to join materials. This technique is widely used in various industries, including metal manufacturing, automotive, aerospace, and medical device manufacturing. The laser beam generates intense heat, allowing for deep penetration and strong welds with minimal distortion. This results in high-quality welds that are both aesthetically pleasing and structurally sound. The precision of laser welding makes it an ideal choice for applications where accuracy and consistency are crucial, ensuring that the final product meets stringent quality standards.

What is Handheld Laser Welding and what kind of machine do you use?

Handheld laser welding involves the use of a portable fiber laser welding machine that emits a focused beam of high-intensity light. This laser beam generates heat that melts and fuses metals with exceptional precision. The operator holds the handheld device, allowing for unparalleled control and accuracy, even in hard-to-reach areas.

By integrating these new sections, the article will provide a comprehensive overview of handheld laser welding machines, highlighting their benefits, applications, and key features, while maintaining the informative and professional tone of the existing content.

Are Laser Welds Strong?

Laser welds are known for their exceptional strength. The precise and concentrated heat generated by the laser beam creates a weld that often exhibits higher strength than traditional welding methods. The weld seam produced by laser welding machines is characterized by its high quality and ability to handle various sizes, ensuring excellent results in metal welding applications. This is due to the minimal heat-affected zone and reduced distortion in the welded material. Additionally, the fast cooling rate of laser welding contributes to the strength of the weld joint. However, the strength of a laser weld also depends on factors such as the type of material being welded, the welding parameters, and the skill of the operator. When performed correctly, laser welds can result in strong and reliable joints, making them a preferred choice for applications that require durability and structural integrity.

“The findings from the third-party evaluation of the samples by Sturbridge Metallurgical Services indicate that LightWELD produces welds that meet rigorous industry standards, including critical aerospace applications; offering both efficiency and quality in welding applications. In summary, LightWELD offers a faster and more efficient welding solution compared to traditional MiG and TiG techniques, thanks to its high power density that enables deep penetration and faster welding speeds. Furthermore, when parts fit up well, filler wire can even be eliminated, resulting in an aesthetically pleasing and strong weld.”

Is Handheld Laser Welding Machine Safe?

The safety of handheld laser welding is really a big question. In recent months, there are loads of Instagram, Facebook, and TikTok videos of people where their summer shorts and t-shirts welding stainless making professional-looking welds with little or no safety/PPE protection. As a result, many of our customers think it’s as easy as buying a laser welding and presto you can start to weld.

When you purchase a laser welder, you must do your due diligence and like any other piece of machinery you bring into your workplace a health & safety risk assessment must be done. Laser welds create radiation, hazardous emissions, potential for fires or explosions, skin damage and potential cancer risks. Compared to traditional argon arc welding, laser welding offers enhanced safety features but still requires strict adherence to safety protocols.

I recently spoke to laser expert and he pointed out that if something goes wrong with a laser welder there is the potential that an operator or someone in the area could lose their eyesight in less than 1/10 of a second and it’s not repairable. Company owners and operators really need to understand how dangerous these machines can be if the proper safety procedures aren’t in place or adhered to – the personal and financial costs would be life-changing.

There is an excellent article written by Matthew Dale of Laser Systems Europe called Questioning the Safety of Handheld Laser Welders. Mr Dale speaks to two experts in the field of laser welding and covers all the points and steps that someone buying or considering buying a handheld laser welding machine should consider making to ensure everyone is protected and safe when using the machine.

The 1000 Watt laser welding machine can weld stainless steel up to 3 mm.

The 1500 Watt laser welding machine can weld stainless steel up to 5mm.

The 2000 Watt laser welding machine can weld stainless steel up to 8 mm.

For welds greater than 0.3mm it is recommended to use a laser welding machine with wire feed. Material thickness less than 1 mm, it is recommended to use the laser welding without wire feed, because the wire feed welding speed is relatively slow without wire feed, which can easily cause deformation.

How much does a handheld laser welding machine cost?

The cost of a handheld laser welder can vary widely based on several factors, including the brand, specifications, power output, and additional features. Generally, you can find entry-level handheld laser welders starting around £15,000 to £35,000. Keep in mind these prices don’t include safety enclosures, extraction equipment or safety/PPE.

Handheld laser welding machines are versatile and capable of performing various welding techniques, including fillet welding, which is ideal for different joint configurations.
