Abstract

The invention discloses a circumferential seam single-pass electro-gas welding machine which is mainly composed of a walking track, a cantilever welding machine, an electro-gas welding head, a front side water-cooling slide block, a back-side forming device, a roller frame base, a driving roller frame and a driven roller frame. The cantilever welding machine is installed on the walking track; the electro-gas welding head and the front side water-cooling slide block are integrated to be installed on the cantilever welding machine; the driving roller frame and the driven roller frame are installed on the roller frame base; a barrel to be welded is placed on the roller frame; and the back-side forming device is installed in the barrel during welding. The circumferential seam single-pass electro-gas welding machine has the advantages that the problem of low efficiencies brought by a layer upon layer stacking welding process is solved so that efficiencies are improved; and simultaneously, welding qualities are high, welding control is accurate, and technological blank of the electro-gas welding machine is filled.

Description

technical field [0001] The invention relates to a pipeline welding processing equipment, specifically a circular seam single-channel gas-electric vertical welding machine, which belongs to the technical field of automatic welding equipment. Background technique [0002] At present, the circular seam welding of the cylinder generally adopts submerged arc welding, gas shielded welding, argon arc welding and other processes, and its common feature is layer-by-layer welding. Due to the layer upon layer welding, the common disadvantage of this type of welding is that the efficiency is not high. And for the high-efficiency gas-electric vertical welding welding process, it has not been able to be applied to the circular seam welding of cylinders both at home and abroad at present. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a circular seam single-channel gas-electric v...
