METHOD FOR SUPPRESSING SOLIDIFICATION CRACKING DURING WELDING OF GAMMA (amp;gamma;) TITANIUM ALUMINIDES

摘要

PURPOSE: A method for suppressing solidification cracking is provided to obtain a welding part on which solidification cracking is not generated during welding of gamma (γ) titanium aluminides. CONSTITUTION: The method for suppressing solidification cracking during welding of gamma (γ) titanium aluminides comprises the process of performing welding by applying electromagnetic waves to a welding part or weaving the welding nozzle side to side so that structure having a high resistance against solidification cracking is formed by suppressing segregation formed along the central line of the welding part when welding gamma (γ) titanium aluminides that are intermetallic compounds having superior high temperature characteristics and low specific gravity.
