Description

Wire guide pipe for welding gun

Technical Field

The utility model belongs to the technical field of the welding technique and specifically relates to a welder is with seal wire pipe.

Background

The wire guide tube is used as a welding wire conveying channel and plays an important role in a welding gun system. The smooth inner wall of the welding wire feeding device can effectively reduce the feeding resistance of the welding wire, and the smaller inner diameter ensures that the welding wire is not bent in the feeding process. Welding wires with high hardness such as carbon steel welding wires and stainless steel welding wires generally adopt steel wire guide tubes, and welding wires with soft materials such as aluminum alloy welding wires and copper alloy welding wires generally adopt wire guide tubes made of insulating materials such as polyethylene and nylon.

However, the use of the wire guide tube made of an insulating material has two disadvantages,

one is the inability to aid in conduction. After the contact tube is used for a period of time, due to continuous friction between the welding wire and the inner hole wall of the contact tube, the shape of the inner hole of the contact tube is irregularly changed, and poor conduction between the welding wire and the contact tube can occur. The service life of the contact tip is greatly reduced, and the welding seam quality is also adversely affected.

Secondly, the guide wire tube is used as a consumable in the system and needs to be replaced after being used for a period of time. In the traditional replacement process of the wire guide pipe, the rear end of a welding gun needs to be detached from the end of a wire feeder, and then the wire guide pipe is drawn out, and the installation height of the wire feeder generally exceeds 2 meters, so that the process of replacing the wire feed pipe is difficult.
