Problems solved by technology

[0002] In the surfacing industry, for the surfacing operation of the ball valve workpiece, as far as the existing domestic equipment is concerned, the spherical surface cannot be automatically welded, because the workpiece needs to be designed and processed according to the standard, and there is a through channel in the ball valve. When surfacing the spherical surface The operator needs to manually control the arc start and extinguish; manual arc start and extinguish will cause welding defects, the area around the spherical surface close to the channel opening is uneven, and the more layers of surfacing welding on the spherical surface, the greater the possibility of welding defects
The surfacing welding efficiency is low, and the operation of the equipment operator is complicated

Embodiment Construction

[0033] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] A method of using new surfacing equipment to realize automatic surfacing ball valve of the present invention comprises the following steps:

[0035] 1) Place the ball valve on the turntable 1 of the new surfacing equipment;

[0036] 2) Turn on the main power supply, welding power supply 22, and welding shielding gas. After the equipment starts up and runs stably, enter the workpiece surfacing mode interface on the remote control 16, and select the ball valve surfacing mode;

[0037] 3) Use the remote control 16 to control the moving beam 7, move the welding torch 13 to the point on the plane of the connecting end 30 of the ball valve body 29, and rotate the turntable 1 to adjust the welding torch 13 and the valve body 29 to ensure that the welding torch 13 and the valve body 29 at the center of the circle;

Abstract

The invention discloses a method for realizing automatic surfacing welding of a ball valve by using novel surfacing welding equipment. For a ball valve that needs surfacing welding, the sizes of different areas are inputted to the novel compact type equipment to implement programming setting; and after ball parameters are set, a welding gun on the equipment is used for correcting the roundness ofa workpiece to make sure that the ball valve and the welding gun that is positioned on the surfacing welding equipment are at the concentric positions. According to the method disclosed by the invention, in a surfacing welding process, the equipment can automatically avoid a ball channel, realizes orderly and smooth arc start and arc blowout, reduces welding defects and improves the surfacing welding efficiency.

Description
