Laser welding is an efficient and precise welding method which uses high energy density laser beam as heat source.
Laser welding is one of the important aspects of laser material processing technology. The welding process belongs to the heat conduction type, the laser radiation heats the workpiece surface, and the heat on the surface diffuses through the heat transfer guide. By controlling the width, energy, peak power and repetition frequency of laser pulse, the workpiece is melted to form a specific molten pool.
Laser welding is a new type of welding method. Laser welding mainly aims at the welding of thin-walled materials and precision parts, which can realize spot welding, butt welding, stack welding, seal welding, etc.,
With the following characteristics:
1. It has high aspect ratio, small weld width, small heat affected zone, small deformation and fast welding speed;
2. The weld is flat and beautiful, and there is no need to deal with or only simple process after welding;
3. The weld has high quality and no porosity, which can reduce and optimize the impurities in the base metal.
the microstructure can be refined after welding. The strength and toughness of the weld are at least equivalent to exceed the base metal;
4. It can be precisely controlled, the focus light point is small, it can be positioned with high precision, and it is easy to realize automation;
5. Welding between some different materials is possible;
