| Abstract: | Can is the critical part of canned nuclear reactor coolant pump motor. This article mainly analyzes the construction of stator can circumferential weld and weldability of can material Hastelloy C276 so far as to provide proper technology method solving difficulty in welding process. A whole technology procedure for can circumferential welding had been summarized and applied in canned RCP motor manufacturing by means of improvement of material cleaning, impulse current applied, back inactive gas shielding, cooling copper chill ring and adjustment position of tungsten electrode and welding wire. |
