Exhaust pipe welding set of compressor upper shell

Abstract

The invention discloses an exhaust pipe welding set of a compressor upper shell. The exhaust pipe welding set comprises a supporting bracket (1) and a rotating disc which is rotatably connected with the bracket (1), wherein a plurality of welding clamps (3) which are used for fixing the compressor upper shell (8) and an exhaust pipe (9) are uniformly distributed in the circumferential direction of the rotating disc (2); the lower end of the exhaust pipe (9) is sleeved by a welding ring (10); a welding gun (7) which is used for welding is arranged on the side edge of the bracket (1); and the welding device further comprises a controller which is used for controlling the rotating disc (2) and the welding gun (7) to be matched to start and stop intermittently. When the welding device is used for welding, the operation is convenient and orderly, the welding performance is stable the changeability is small, the undesirable phenomenon of weldment leakage is reduced, the welding quality of the weldment is greatly enhanced and relatively strong practicability is achieved.

Description

technical field [0001] The invention belongs to the field of welding technology, and relates to a welding device for welding an exhaust pipe of an upper casing of a compressor. Background technique [0002] Traditionally, manual brazing is used for welding the exhaust pipe of the upper shell of the compressor. The welding quality is closely related to the welding skills of the brazing personnel. The arc welding is difficult, the work intensity is high, the efficiency is low, and the welding defect rate is high. If the external temperature is high and the cooling time after welding is short, taking out the solder before it is completely cooled will easily lead to welding cracks and increase the defective rate of welding products, and manual brazing uses manual wire feeding, and the stability of solder consumption is poor, which affects the welding quality And the aesthetics of welding. Contents of the invention [0003] The purpose of the present invention is to solve the ...

[0002] Traditionally, manual brazing is used for welding the exhaust pipe of the upper casing of the compressor. The welding quality is closely related to the welding skills of the brazing personnel. The arc welding is difficult, the work intensity is high, the efficiency is low, and the welding failure rate is high.

If the external temperature is high and the cooling time after welding is short, taking out the solder before it is completely cooled will easily lead to welding cracks and increase the defective rate of welding products, and manual brazing uses manual wire feeding, and the stability of solder consumption is poor, which affects welding quality and welding aesthetics
