Problems solved by technology

Specifically, the traditional conduction method is to apply pressure to the steel body current collector to maintain stable contact with the tube row to complete the conduction, but there are several shortcomings in this method: 1. Direct surface-to-surface contact friction, the wear of the tube row The degree is large and the replacement is frequent; 2. The accumulation of welding slag generated after welding is easy to cause damage to the tube; 3. The flow of conductive current on the tube row is unstable, which may affect the welding quality

Abstract

The invention discloses a film type wall conductive device and is used for providing electric power for tube bank welding. The film type wall conductive device comprises a conductive mechanism, a barmaterial which can roll on a tube row, and a long shaft which is connected with the conductive mechanism, wherein the bar is mounted on the outer side of the long shaft. Compared with the prior art, the film type wall conductive device is advantaged in that the device is simple in structure and reasonable in design, the abrasion degree of the tube row during welding can be reduced, welding slag accumulation is prevented, that the conductive current on the tube row has stability is guaranteed, and reliability of film type wall tube row welding can be improved.

Description

technical field [0001] The invention relates to the field of membrane wall pipe row welding, in particular to a membrane wall conductive device. Background technique [0002] At present, the technology of multi-pipe side-by-side welding in the membrane wall industry has developed to a mature and stable technical level. The stability of multi-pipe side-by-side welding quality is deeply concerned by the pipe row production factory. According to experiments, the conductivity of the tube row Good or bad will directly affect the welding quality, such as large spatter, undercut and many other problems are caused by poor conductivity. Specifically, the traditional conduction method is to apply pressure to the steel body current collector to maintain stable contact with the tube row to complete the conduction, but there are several shortcomings in this method: 1. Direct surface-to-surface contact friction, the wear of the tube row The degree is large and the replacement is frequent...
