Benefits of Laser Welding



When it comes to metal fabrication and industrial welding, TIG welding has long been unmatched for its versatility and quality, until now. New on the scene, high-powered laser welding uses a highly-concentrated heat source to weld metal with intricate precision. But, what is all the fuss really about? Does laser welding really live up to the hype?

Let us start at the beginning. What is the definable difference between TIG welding and laser welding? Two different methods for joining materials, in this case metals, TIG welding has long been the go-to for welders. Using a combination of heat and filler metal, TIG welding melts and bonds seams together. This traditional method is used for a reason. It is cost-effective, enables detailed welds and most machine operators are familiar with the techniques. Laser welding, on the other hand, uses a laser beam to direct a concentrated blast of energy at one point until it reaches its melting point and bonds. A versatile method, laser welding does not require filler, produces less heat and provides a high-quality weld.

What is so much better about laser welding? For one, while it takes years to become proficient in TIG welding, laser welding requires less training time and less experience. Even a novice welder should be able to use a laser welder to produce a finished fabrication build with minimal to no defects.

Secondly, the turnaround speed for projects that use laser welding can be as much as 25% faster when compared with traditional TIG welding. The main reason for this is that laser welding limits the chances of thermal deformation and gets rid of any need for pre- or post-weld processing steps, such as pre-brushing metals.

Thirdly, laser welding has wider material compatibility. With its high-heat generation, TIG welding is not great for all materials, some of which include aluminum and stainless steel. On the other hand, laser welding is compatible with both of those materials, as well as carbon steel, brass and even plastics. Plus, it handles thicker materials with ease, providing better weld penetration depth.

"One of only five laser welders in the nation, at Acosta Sheet Metal Manufacturing, we have seen the effectiveness of laser welding for ourselves," said a company spokesperson. "Since we invested in our laser welder in 2021, not only have we seen a dramatic increase in productivity, but we have also seen how its use positively impacts the efficiency of our workflow. The ability to deliver consistent, high-quality products in less time is invaluable to us and our customers. We are lucky to also have the support of the Sheet Metal Workers' Local 104 and the Bay Area Industry Training Fund, which continues to invest in the next generation of welders. In the future, laser welding is going to be vital for industries like sheet metal manufacturing, automotive manufacturing, medical device manufacturing, aerospace and more."
