Technological advancements keep on hitting the welding industry and laser welder is one among the latest entry. The laser beam welding (LBW) is a modern welding process that includes high energy beam and has already continued to expand into modern industries and new applications. There are many advantages with laser welder like deep weld penetration and minimizing heat inputs that make it popular recently. Moreover the manufacturers have also switched to the automation of welding processes and this has caused the expansion in using high technology for improving the product quality. The laser welding process also enables accurate control of welding.

The laser welding equipment is used in defense/ military, electronics, research and development, medical, sensors & instrumentation, petrochemical refining and also communications and energy. There are many advantages in using the laser welders like deep and narrow welds are possible during the welding, there would be absence of distortion in the welds, also the heated affected zones would be less in the welds and precise metallurgical quality will be established in the welds. It also has the ability to weld smaller and thinner components. The travel speed would be greater and there is room for non-contact welding in laser welders.
