The processes of laser cutting machine filler wire

Welding wire for laser cutting machine laser has the effect of absorption, reflection and projection. Filler wire to join, make laser cutting machine laser welding process is more complicated than when no wire filling, especially considering the issues of interaction of laser beam with wire. Wire filling laser welding, the incident laser beam after through the surface plasma cloud, first role on the filler wire. Many studies have shown that laser cutting machine laser beam onto the wire, usually occurs in three aspects: part of the laser energy absorbed by wire and wire heating, melting, become a part of the molten pool. Part of the wire surface reflection; The remaining part of the beam is through the holes formed in the wire, through the wire to the following workpiece heating. A typical case of the interaction between laser beam and wire, wire filling laser welding thick plate with groove clearance when observed after removing the side butt welding phenomenon. Beam and wire after three parts, the energy distribution not only affects the melting of wire, affect the efficiency of welding, and with the parent metal melting, wire filling welding process stability and weld has much to do.
