A LASER-ARC HYBRID WELDING METHOD FOR LOW-CARBON STEEL

摘要

The present invention relates to a laser-arc hybrid welding method for low-carbon steel, wherein the laser-arc hybrid welding method is based on a rule regarding the effect of laser-arc bonding characteristics and laser-arc hybrid welding parameters, welding parameters and It is developed by optimizing the groove size of the weld joint in each layer (path) of the multi-layer weld to be welded through the orthogonal arrangement test method. The laser-arc hybrid welding method for low carbon steel has advantages such as low heat input, wide melting depth, small welding deformation and high welding speed. In addition, the area of the joint and the width of the heat affected zone can be reduced, and the emission of harmful gases, smoke, dust, etc. can be reduced, thereby improving welding quality and welding efficiency, reducing production costs, improving product quality and reducing environmental pollution. can be alleviated
