Description

Technical Field

[0001] The invention relates to the technical field of laser welding, in particular to a metal profile welding processing device. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. It radiates a high-intensity laser beam onto the metal surface. Through the interaction between the laser and the metal, the metal absorbs the energy of the laser and quickly melts and solidifies, thereby achieving welding. The laser beam energy is highly concentrated, which can make the welding part reach a very high temperature in a short time, achieving rapid welding. The laser beam spot is small, which makes the laser welding precision high. Laser welding does not require direct contact with the weldment and is non-contact welding, which avoids mechanical damage to the weldment surface and facilitates automated welding.
