Abstract

PURPOSE: To obtain perfect shield effect by enclosing the whole outer circumference of the tube of the groove part with a case and welding while spurting shield gas of low pressure and small flow rate after filling the case with the shield gas.
CONSTITUTION: When shield gas is spurted after enclosing the weld zone with a case 14 and passing a shield cup 17, the shield gas flows efficiently into the inside of tubes 1, 1' to be welded through the gap of the weld groove to replace the inside air. After starting welding, welding is performed making the feed of shield gas from the shield cup 17 low pressure and small flow rate.
