Abstract

PURPOSE:To eliminate the formation of clearances on the side to be joined to a heat exchange medium, to facilitate the removal of oxide scale and to improve corrosion resistance by using a press metal made of copper of a diameter slightly larger than an opening in connecting tubes to the opening part of a plate. CONSTITUTION:Both sides of an opening part 2 of a steel sheet 1 or the like are sandwiched by a steel tube 3 having a mouthpiece having an inside diameter approximately equal to or slightly smaller than that of the opening 2 and a press plate 6 made of steel having a diameter slightly larger than that of the opening 2. While a part of the plate 1 is melted by a TIG torch 7 than the plate 6 side in this state, the sheet 1 is welded to a moutpiece 3 and the mouthpiece 3 is joined to the opening part 2 of the sheet 1. By this method the weld zone is limited to a minimum. The resistance welding of the near the mouthpiece 3 is made possible and bulging is adequately accomplished.
