Laser Welding in different industries requires different welding process, and now we have several mature welding processes.
Laser welding is a high-precision laser welding method with laser beam of high energy density as a heat source. It has the advantages of high welding speed, high strength, narrow weld, small heat affected zone, small workpiece deformation, etc.
A laser welding method of double wedge laser vibration, which can achieve by disposing a dedicated wobble vibration module on the laser head. And then the focus spot produces spiral weld in the case of laser head moving.
Using the filler metal with a lower melting point than the base metal, heating the filler metal to a melting point higher than filler metal but lower than the melting temperature of the base metal. Then the liquid filler metal fill the gaps.
In the process of welding,add the double-spot module to the lens, the medium small spot is responsible for deep welding, the big spot is responsible for shaping, which can achieve the welding more smooth and without cracking.
Through the conversion of the optical path, the traditional conical focusing beam is transformed into the circular cone-shaped focusing beam, so that the metal wire and the center line of circular laser beam can be transported coaxially.
