Background technique

As the welding process and welding requirements are getting higher and higher, and the production rhythm is getting faster and faster, the demand for mechanization in the front-line production departments is becoming more and more obvious. However, due to external factors such as the deviation of the end face processing of the material pipe, the error of the operator, and the improper welding parameters, defects such as welding penetration, incomplete penetration, and dry bottom layer appear in the welding process. But if you want to repair by yourself when you encounter these, there is nothing you can do. You can only mark the welding defect to leave it in the fluorescent inspection for repairing.

For example, a straight pipe butt welding machine disclosed in publication number CN102489905B includes: a telescopic mechanism arranged on the straight pipe butt welder and located on the outlet side of the straight pipe, which can be extended and retracted along the conveying direction of the straight pipe, and a telescopic mechanism connected with the telescopic mechanism Actively connected active cutting rack.
