The invention relates to a flexible ultrasonic-assisted
argon tungsten-
arc welding working platform, and belongs to the technical field of
welding. The ultrasonic tool
system and the
welding gun are fixed in the transverse
movement system through a clamp, the ultrasonic tool
system and the
welding gun are positioned and moved in the direction perpendicular to a welding seam through the transverse
movement system, a workpiece is fixed to a sliding table of the longitudinal
movement system, and the workpiece moves in the welding seam direction through the longitudinal movement
system. The longitudinal movement system is fixed in the vertical lifting system, movement of a workpiece in the vertical direction is completed through the vertical lifting system, the ultrasonic tool system is perpendicular to the surface of the workpiece, and
ultrasonic vibration is transmitted between a spherical rolling head at the front end and the workpiece in a point-surface
contact mode. The device has the advantages of being novel in conception, stable and reliable in equipment, good in balance, resistant to interference, high in
assembly precision, space-saving, flexible and convenient to operate, and capable of meeting the requirements for high-quality, high-precision and low-cost ultrasonic-assisted
tungsten electrode argon arc welding of workpieces with different weld joint shapes.
