Abstract

The invention relates to the technical field of welding, in particular to a compound pipe longitudinal joint automatic welding device which mainly comprises a double welding gun movement mechanism, a control system, welding power supplies and a welding fixture. The double welding gun movement mechanism is composed of a movable platform, a left welding gun, a right welding gun and a cross sliding frame, wherein the two welding guns are provided with wire feeding mechanisms and welding power supplies respectively. The control system is located on the left side of the welding fixture, and the two welding power supplies are connected with the control system. The welding fixture comprises a welding front-rear symmetric supporting device, a lower supporting device, a supporting mandrel, a pneumatic key pressing device and a precision movement sliding rail. According to the welding device, a double metal compound pipe longitudinal joint with a diameter of 200-500 mm, a length of 1800 mm and a thickness of 4-7 mm can be clamped quickly and reliably, the control system can finish welding device control, welding track planning, welding parameter setting and welding process monitoring, and the double metal compound pipe longitudinal joint is automatically welded.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an automatic longitudinal seam welding device for composite pipes, which is suitable for welding the longitudinal seams of stainless steel and carbon steel bimetallic composite pipes. Background technique [0002] At present, most of the welding processes of bimetallic composite pipes are manual tungsten argon arc welding, root welding, transition welding, electrode arc welding, filling welding, and cover welding. The stability of welding quality is difficult to guarantee, and the welding efficiency is low. With the popularization and application of bimetallic composite pipes, it is more and more urgent to realize the automation of the welding process of bimetallic composite pipes. Contents of the invention [0003] The invention provides an automatic longitudinal seam welding device for a composite pipe, aiming at effectively realizing the clamping and positioning of the comp...
