Welding machine of inner ring board of steel pipe and application method thereof

Abstract

Provided is a welding machine of an inner ring board of a steel pipe. The welding machine comprises a rotary mechanism, a welding gun and a welding gun control mechanism. The rotary mechanism is arranged on rotary bodies (1) and used for supporting and driving the steel pipe (7) to rotate. The welding machine is characterized in that the welding gun control mechanism comprises a support, a welding handle and a run-on switch; the support (4) is an iron pier support arranged outside of an opening of the welded steel pipe (7); the welding handle (5) is a metal pipe having one end for firmly fixing the welding gun (2) and the other end stretching out of the opening of the welded steel pipe (7) to be placed on the support (4); and the run-on switch (3) is arranged on the welding handle (5).The welding machine of the inner ring board of the steel pipe and the application method thereof have following beneficial effects: the combined welding machine is advantaged by being simple in structure, convenient in operation, uniform in welding seams and fine in welding quality; intensity of labor is reduced; and working efficiency is increased.

Description

technical field [0001] The invention relates to a steel pipe welding device, in particular to a steel pipe inner ring plate welding machine and its use method. Background technique [0002] During the processing of steel structural members, many tubular members are often processed, and designers usually add ring stiffeners at different depths from the inner wall of the steel pipe to the nozzle to strengthen the strength of the steel pipe. [0003] For the welding of the ring plate on the inner wall of the steel pipe with a diameter of more than 800mm, most steel structure manufacturers let the welder directly climb or sit inside the pipe for welding. , the welder can no longer enter the pipe, basically the pipe is cut off at a certain distance from the inner ring plate, so that the inner ring plate is closer to the nozzle to facilitate welding. This operation increases the number of pipe butt joints, and when there are many inner ring plates in the pipe, the number of pipe ...

AI Technical Summary

Problems solved by technology

This operation increases the number of pipe butt joints, and when there are more inner ring plates in the pipe, the number of pipe segments will be more, which not only affects the quality of the steel structure, but also increases the labor intensity of the workers

[0004] Therefore there is above-mentioned inconvenience and problem in the welding method of known steel pipe inner wall annular plate
