White body

Apply fiber laser technology to weld "challenging" materials such as galvanized steel, aluminum and high-speed steel。

  • Reduced post-processing Realize zero gap welding of galvanized steel without spatter and welding hole。
  • Remove packing Avoid "centerline crack" when welding 6000 aluminum alloy - do not use filler wire。
  • To prevent cracking Welding high strength steel at fast feed rate will not produce subsequent cold cracks。

Aluminum soldering

Using ARM laser for 6-series aluminum welding, no filler wire is needed, centerline crack is avoided, and spatter is greatly reduced。 In addition, the welding depth is adjusted while keeping the gap width constant。

Galvanized steel welding

ARM lasers can achieve high-quality, zero-gap lap welding of galvanized steel without bursting, opening up new production possibilities。

Laser welding of high strength aluminum with cast aluminum

Both high-strength aluminum and cast aluminum offer proven benefits for automotive manufacturing, but also pose challenges for laser welding。 In particular, both are prone to thermal cracking and spatter。 These problems were solved by using a welding system based on coherent's ARM laser and ThyssenKrupp's new LSK06 laser machining head。
