Industry Challenges: Ventilation ducts are commonly made from thin galvanized or stainless steel sheets that are sensitive to burn-through and distortion. Our Solution: Low-heat-input laser welding produces smooth, continuous and well-sealed seams while minimizing deformation. Recommended Products: Air-Cooled Handheld Laser Welders, Water-Cooled Handheld Laser Welders, Collaborative Robot Laser Welding Systems.
