Abstract

The invention provides a barrel-like workpiece internal narrow space all-dimensional welding device which comprises an all-dimensional fixing ring and a welding telescopic gun, the welding telescopic gun is slidably and rotatably arranged on the all-dimensional fixing ring, and the all-dimensional fixing ring is arranged on a workpiece in a sleeving mode; the welding telescopic gun comprises a driving mechanism, and the driving mechanism is in driving connection with a wire feeding welding gun and an image obtaining unit. According to the device, inner wall welding operation can be conducted on a narrow space where personnel cannot enter conveniently, the field operation difficulty of workers is remarkably reduced, and the welding quality is improved.

Description

technical field [0001] The invention belongs to the field of welding, in particular to an omnidirectional welding device in a small space inside a barrel-like workpiece. Background technique [0002] Many equipment in the industrial field are designed to be approximately barrel-shaped, with narrow and deep spaces in the middle, such as large valves, thick-walled pipes and other equipment. In the manufacturing process of such equipment, internal defects cannot be completely avoided. During long-term use, the inner wall of such equipment may also be defective and expand, jeopardizing the safety of the equipment. Eliminating such defects in time and performing repair welding can improve the safety factor of the equipment. However, due to the narrow and deep space in the middle of such equipment, people cannot enter, even if people can barely enter, it is very difficult to operate the equipment inside for welding repair, and it is extremely difficult to guarantee the welding q...
