A method of automatic surfacing three-way valve using new surfacing equipment

Abstract

The invention discloses a method for automatically surfacing a three-way valve using new surfacing equipment. For a three-way valve body that needs surfacing, the size of different areas is input on the new compact equipment for programming and setting. The parameters of the three-way valve body After setting, use the welding torch on the equipment to calibrate the workpiece to ensure that the valve body and the welding torch on the surfacing equipment are at the same center position. After setting, the equipment can automatically avoid the ball channel during the surfacing welding process, and the arc starting and extinguishing are neat and smooth, reducing welding defects and improving the surfacing welding efficiency.

Description

technical field [0001] The invention relates to the field of surfacing welding, in particular to a method for using new surfacing equipment to automatically surfacing a three-way valve. Background technique [0002] In the surfacing industry, for the surfacing operation of the three-way valve body workpiece, as far as the existing domestic equipment is concerned, the three-way valve body surfacing area is relatively complicated, and there are intersecting lines in the main channel area, which cannot realize automatic welding. When the surfacing main channel and the intersecting line are inside, the operator needs to manually control the arc start and extinguish; manual arc start and arc extinguish will cause welding defects such as welding incomplete fusion and lack of meat (insufficient size), and the area around the intersecting line Uneven, and the more layers of surfacing welding, the greater the possibility of welding defects. There are often problems of low surfacing ...
