Coherent | Body-in-White: Zero-Gap Laser Welding of Galvanized Sheet Metal (Automotive Production)

Zero-gap welding of galvanized steel continues to be a challenge in automotive industry as rapid vaporization of the volatile zinc runs the risk of blowing out the molten steel. The result is an inconsistent weld seam with pores, as well as spatter that needs to be subsequently cleaned. Here is how we help our customers address this challenge: • Our adjustable ring mode fiber laser enables controlled gas venting that eliminates spatter, even when the parts are clamped together with zero gap. • The symmetric beam can easily follow the weld seam on a part that has a curved or a complex shape, greatly simplifying the use of remote welding scanners More details: https://www.coherent.com/lasers/laser/highLight-fl-arm-fiber-laser Founded in 1966, Coherent Inc. is one of the world’s leading providers of lasers and laser-based technology for industrial, commercial, and scientific customers.
