Abstract

The invention discloses a double-torch pipeline full-position automatic welding machine. The double-torch pipeline full-position automatic welding machine comprises a welding tractor which is arranged on a guide rail, a welding control box, a wire feed box, a welding power supply and a manual control box; the welding tractor is provided with a travelling mechanism, two welding torches which are controlled by a swinging mechanism, and a height adjustment mechanism; a controller is arranged in the welding control box; the double-torch pipeline full-position automatic welding machine is characterized in that: the welding tractor is provided with a laser tracking probe and a sensor which are connected with the controller in the welding control box respectively; and the controller is connected with a computer. A welding line is automatically tracked by the laser tracking probe, and a welding process is not needed to be interfered by a welder, so welding automation is realized and labor intensity of the welder is reduced; under the control action of the computer, the welding power supply provides welding current and arc voltage which are matched with the position, and welding forming quality is improved; and a cable number is simplified and maintenance and expansion capacity of a system is improved.

Description

technical field [0001] The invention relates to welding equipment, in particular to an all-position automatic welding machine for a double-torch pipeline. Background technique [0002] Welding is an important link in the laying of submarine pipelines. Welding quality directly affects the service life of pipelines, and welding efficiency directly affects construction costs. The construction method of pipeline welding has gone through three development stages: manual arc down welding process, semi-automatic welding process and fully automatic welding process. The main methods involved are gas metal arc welding (GMAW), self-shielded flux cored arc welding (FCAW) and manual arc welding. After the 1970s, the application of gas metal arc welding (GMAW) in pipeline construction developed rapidly, and external welding (GMAW) single-side welding and double-side forming have become the mainstream process of pipeline construction in the world. The early (GMAW) automatic welding was s...
