Problems solved by technology

[0002] Existing conventional TIG, MIG / MAG welding requires the tip of the torch to be perpendicular to the vertical direction of the workpiece, and the workpiece to be welded needs to be pickled before welding. Therefore, the requirement for the assembly gap before welding is high, resulting in an increase in welding costs
And: conventional TIG, MIG / MAG welded joints are prone to welding defects such as pores, incomplete fusion, cracks, etc., and the first-time pass rate of welds is low

Abstract

The invention relates to a girth welding system, in particular to a variable polarity plasma vertical girth welding system. The system comprises an integral base, a precision manipulator, a precision headstock positioner, X-type supporting assemblies, a movable tailstock and a welding head. The precision manipulator comprises a stand column assembly, a cross arm assembly and a translation trolley. The precision headstock positioner and the movable tailstock are arranged on the same straight supporting track. The X-type supporting assemblies are arranged on the corresponding surfaces of the precision headstock positioner and the movable tailstock. The precision manipulator is arranged on a base straight guide rail parallel to the supporting track. The welding head is mounted at one end of the cross arm assembly of the precision manipulator. Compared with the prior art, the variable polarity plasma vertical girth welding system has the following advantages of being wide in application range, high in welding adaptability, low in welding cost, high in welding quality, high in welding efficiency and small in deformation.
