First adapter to be welded 11 is alignd, and then gas pawl cylinder 31 drives left correction arm 32, right correction arm 33 disengaging first, second to be welded
Pipe 11,12.
Then, drive cylinder drives respective sliding panel slide in opposition, the front and back end of two welding bars 21,22 to close up, and welds
Arc frame 29 closes up into the high frequency brazing coil 200 of a closure, and the first nitrogen protective housing 28, the second nitrogen protective housing 27 are closed
Hold together to surround nitrogen protection box body, two conducting blocks 211 are connected on copper bar 71, it is ensured that be in close contact.Then, high frequency brazing coil
200 are initially powered up work, plus hot solder so as to be melted in the welding position of first, second adapter to be welded 11,12, high frequency brazing
When coil 200 works, nitrogen supply (NS) equipment exports nitrogen in nitrogen protecting box, and nitrogen rises and is protected from oxidation.Welding
After finishing, all of mechanism and parts are returned to original position, and now first, second between compressor 9 and reservoir 10 is to be welded
The welding of adapter 11,12 is completed.
