Moving trolley of submerged-arc welding machine and control method and control device of moving trolley

Abstract

The invention relates to a control method of a moving trolley of a submerged-arc welding machine, a control device of the moving trolley and the submerged-arc welding machine. The control method comprises the following steps of setting preset operating parameters of a moving trolley of the submerged-arc welding machine, when the moving trolley of the submerged-arc welding machine operates according to the preset operating parameters, collecting feedback operation parameters of the moving trolley of the submerged-arc welding machine, performing PID operation on the preset operation parameters and the feedback operation parameters to adjust the preset operation parameters of the movable trolley of the submerged arc welding machine, so that the moving trolley of the submerged-arc welding machine is operated according to the adjusted preset operating parameters. According to the control method disclosed by the embodiment of the method, automatic PID adjustment can be carried out on the running state of the moving trolley of the submerged-arc welding machine, so that the running state of the submerged arc welding machine moving trolley is matched with the welding speed, the welding precision and the welding quality are improved, the operation state of the submerged-arc welding machine moving trolley has high-precision and automatic control functions, and great convenience is broughtto the operation process of technicians.

Description
