Simple welding workbench capable of horizontally rotating

Abstract

The invention relates to a simple welding workbench capable of horizontally rotating, in particular to an auxiliary tool for circumferential fillet welding. The welding workbench mainly solves the problem that the welding quality and efficiency of a connecting pipe and the circumferential fillet welding such as a flat welding flange on a fixing platform is not high; the welding workbench comprisesa bottom plate, a stand column, a rolling bearing and a flat board plate, and a spot welding is carried out for fixing; the tool is simple and firm in structure and flexible in movement, excess material is prone to be adopted for manufacturing in site; a theory that an inner ring of the rolling bearing is not move and an outer ring rotates is fully utilized so that a welder can adjust the rotation of the flat board plate according to the welding speed of the welder; a welding position is kept unchanged by continuously changing the position of a workpiece, so that the stability of an operationprocess is ensured, and the welding efficiency is greatly improved while the quality of a welding seam is guaranteed.

Description

technical field [0001] The invention relates to a simple horizontal transfer welding workbench, in particular to an auxiliary tool for circular fillet weld welding. Background technique [0002] Chemical equipment manufacturing and maintenance sites often encounter various plate and tube welding structures such as the welding of pipe joints and flat welding flanges to the circumferential fillet welds. After such welds are grouped, they are generally placed on a fixed platform for manual welding. Since the position of the platform is fixed, there are two methods for welding such circular fillet welds. One is that the welder moves around the position of the weld for welding. This method has poor arc stability during the position movement of the welder and directly Affects the shape and quality of the weld; another method is that the welder does not move, maintains a stable welding arc, and welds by turning the workpiece to his face, but this method must weld a section, stop, t...

[0002] Chemical equipment manufacturing and maintenance sites often encounter various plate and tube welding structures such as the welding of pipe joints and flat welding flanges to the circumferential fillet welds. After such welds are grouped, they are generally placed on a fixed platform for manual welding. Since the position of the platform is fixed, there are two methods for welding such circular fillet welds. One is that the welder moves around the position of the weld for welding. This method has poor arc stability during the position movement of the welder and directly Affects the shape and quality of the weld; another method is that the welder does not move, maintains a stable welding arc, and welds by turning the workpiece to his face, but this method must weld a section, stop, turn one side, and the welding is continuous Interruption, arc ignition and arc extinguishing times are many, the welding quality is also affected, and the welding efficiency is low
