Abstract

The invention relates to an internal supporting and heat dissipation device for welding of a thin-walled half pipe and a using method of the internal supporting and heat dissipation device. The internal supporting and heat dissipation device comprises an upper base plate, a lower base plate, a screw sleeve, a first rotating screw and a second rotating screw, wherein the two ends of the screw sleeve are connected with the first rotating screw and the second rotating screw in a threaded mode correspondingly; and the screw sleeve, the first rotating screw and the second rotating screw are located between the upper base plate and the lower base plate, the upper base plate is supported by the first rotating screw, and the lower base plate is supported by the second rotating screw. By adoption of the internal supporting and heat dissipation device for welding of the thin-walled half pipe and the using method of the internal supporting and heat dissipation device, the welding quality of the thin-walled half pipe is greatly improved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an internal support cooling device for welding thin-walled half-side pipes and a method for using the same. Background technique [0002] The pipeline system is an important part of the pressurized delivery system of a spacecraft. The delivery pipelines for oxidizers and combustion agents are usually large in diameter. Heavy, this kind of pipeline mostly adopts aluminum alloy thin-walled structure. At present, the bending technology cannot realize the direct bending and forming of this kind of pipeline. In the actual production process, the elbow part of this kind of pipeline is mostly made of two half-side pipe sheet metal parts through tailor welding, and the welding method mostly uses tungsten electrodes. Argon arc welding. [0003] Due to the extremely thin wall thickness of such products, if a larger welding specification is selected during the welding process, it is easy...
