Latest company news about What are the methods and steps of ultrasonic assisted laser welding steel rim?

The company has developed an ultrasonic assisted laser welding method for steel wheel rims, which includes the following steps: (1) grinding, cleaning and rounding the steel plate to be welded; (2) Place the treated round steel ring to be welded on the welding fixture for butt joint, clamping and fixation, and the back of the butt joint of the steel ring is equipped with a gas protection device with the same radian as the steel ring; (3) Adjust the position of laser beam and ultrasonic wave; (4) Welding shall be carried out according to the set process parameters, and the back of the weld shall be fully fused to ensure single-sided welding and double-sided forming. During the welding process, inert gas shall be used to protect the back of the weld pool. The welding method can increase the peak temperature of the molten pool in the welding process, reduce the laser power in the welding process, reduce the porosity defects in the weld, and obtain the welded joint of steel wheel rim with good shape and high elongation.
