Issues in the evaluation of heat exchanger welding processes
Thread Content
Are 3 process evaluations required for the strength welding of heat exchangers? 1. Welding procedure qualification for covering the thickness of the heat exchange tube walls. 2. Welding procedure qualification for covering the thickness of the tube sheet. 3. Additional welding procedure qualifications for joining the heat exchange tubes and the tube sheet. I hope everyone will actively participate in the discussion. Thank you! ! !
That’s absolutely right. I have experienced gauge welding.
