Abstract

The process of laser deep penetration TIG hybrid welding of thin stainless steel is studied to ensure that the maximum welding speed can be achieved under the condition that the weld is well formed. Aiming at the problem of poor accuracy in actual welding production, the technology of laser deep penetration TIG hybrid welding was applied to study the process adaptability of the pair of gaps and misalignments. The correlation between laser and arc is analyzed by using high-speed video to observe the welding arc shape. The experimental results show that when the laser power is 3.5 kW, welding current is 150 A, 2 mm stainless steel can get a good weld at a welding speed of 5 m/min, when the laser power is 4.0 kW, welding current is 150 A, 4 mm stainless steel can get a good weld at a welding speed of 2 m/min. Laser arc hybrid welding of thin stainless steel has good adaptability to misalignment.
