Title:
WELDING METHOD AND DEVICE CAPABLE OF VARIABLE-AMPLITUDE OSCILLATION AND WELDING ROBOT
Document Type and Number:
WIPO Patent Application WO/2019/041984
Kind Code:
A1
Abstract:
A welding method capable of variable-amplitude oscillation comprises: calling a pre-configured measurement sensor to obtain groove information of a groove; establishing, according to the groove information, a Cartesian coordinate system, and calculating, according to a preset step length of a welding torch, coordinates of each welding point on a groove surface on two sides of the groove; and generating, according to the calculated coordinates of each welding point, a corresponding oscillation path of the welding torch, and controlling the welding torch to perform welding along the oscillation path. The invention also relates to a device capable of variable-amplitude oscillation and a welding robot having the device. The welding method and device and the welding robot effectively weld a component having a wedge-shaped or flare groove, and solve the technical problem in the prior art that using a welding robot to weld asymmetrical components is prone to result in a defective weld.
