a welding machine

Abstract

The invention provides a welding machine which is applied to backing welding of various steel equipment structures and comprises rails, a welding device and a square welding bracket, wherein the square welding bracket covers the rails to allow the rails to be positioned at the bottom end of the square welding bracket; the square welding bracket is provided with a penetration structure allowing a welding material to pass in extension directions of the rails; the welding device comprises a welding machine controller, a connecting arm and a welding gun; the welding material is mounted on the rails and enters the penetration structure of the square welding bracket in the extension directions of the rails; welding tips of the welding gun are aligned to welding junctions of the welding material; the heights from the welding tips to the rails are controlled by the welding machine controller to allow the welding tips to be close to the welding junctions; and as the welding material passes through the penetration structure along the rails, the welding gun welds the welding junctions of the welding material. The welding machine can effectively solve the problems of low efficiency, difficult appearance forming, high cost and the like of manual backing welding.

Description

technical field [0001] The invention relates to the field of iron and steel welding, in particular to a welding machine. Background technique [0002] At present, there are many kinds of equipment for iron and steel welding. Since the welding material is not used for back welding, it is easy to burn through the welding material, resulting in the flow of metal liquid, waste of material, poor process and structural performance, etc., and it cannot be connected with other welded parts. . Therefore, backing welding is essential in steel welding, and the backing welding method currently used in the backing welding process is usually manual backing welding. For example, in butt welding with thick single-sided gaps, in order to prevent angle deformation or prevent burn-through during automatic welding, the welding of a bottom pass at the root of the groove on the back of the joint is done by manual welding. of. [0003] Welding in the prior art is all to set up the welding posit...

AI Technical Summary

Problems solved by technology

Due to the relatively high quality requirements for steel bottom welding, traditional welding equipment cannot meet the quality requirements for bottom welding, so the current process of bottom welding is still manually operated

However, the manual operation of bottoming welding not only has high requirements for operators, but also has a large loss in welding time and work cost.
