FAQ
Welding spatter, what to do about it
Clean the surface of the material or workpiece before laser welding to remove oil stains and contaminants. Appropriately reduce the welding energy to reduce spatter.
Welding with cracks, how to deal with
Wire filling, preheating and other measures can reduce or eliminate cracks. Wire filling can increase the amount of metal in the molten pool and reduce the contraction force; preheating can reduce the temperature gradient and slow down the cooling rate.
Welding with porosity, how to deal with
Clean the weld surface to improve the volatilization of zinc when heated. In addition, the blowing direction also affects the generation of porosity. The blowing direction should be the same as the welding direction so that the gas can be discharged from the molten pool.
Welding with biting edge phenomenon, how to do
Control the processing power and speed matching of the laser welding machine to avoid edge biting. For the weld edge biting found by inspection, it can be polished, cleaned and repaired to meet the requirements of the acceptance standards.
