What Are The Hazards Of Laser Welding And Laser Cutting And How To Prevent Them?

1. Harm caused by laser radiation in laser welding and laser cutting On the one hand, laser welding has the danger and harmfulness of conventional welding (such as mechanical injury, electric shock, burning, etc.); On the other hand, its unique harm is laser radiation. With high laser intensity, it can produce extremely violent interaction with …

Laser Wire Filling Welding: Principle, Characteristics And Parameters

Laser wire filling welding is similar to ordinary wire filling welding. While the laser irradiates the weld, feed in the corresponding welding wire. Laser wire filling welding solves the problem of strict clamping requirements for weldments, and can realize the welding of thick weldments with low-power laser. More importantly, proper wire filling can improve the …
