Abstract

PURPOSE: To form a welding part which is not polluted by active gas and does not generate fragileness, by inserting a titanium tube into the fitting hole of the tube plate to extend the tube end and by lowering the welding current to weld the same position after welding the tube end.
CONSTITUTION: The end part of tube fitting hole 4 of titanium or titanium clad tube plate 2 is tapered. Thin titanium tube 1 is inserted into fitting hole 4, and the end part of this tube is extended to the tapered part of fitting hole 4. Next, the tube end and tube plate 2 are subjected to TIG welding without a filler metal to form a weld casting. Further, this weld metal 7 is subjected to TIG welding by lowering the welding current and is fused again to form weld casting 7' of a casting depth shallower than the first. By this method, titanium tube 1 and titanium tube plate 2 for the heat exchanger are connected without blowholes and bubbles.
