N2 - Generally, nickel superalloy Inconel 625 is good weldability. However, it should be kept in mind his tendency to hot cracking during welding. Gamma matrix is strengthening by the alloying elements chromium, titanium, niobium. These elements favour the formation of carbides and intermetallic compounds that may cause embrittlement and hot cracking in a welded joint. Based on research the system Gleeble 3800 and transvarestraint test appointed criterion for susceptibility to hot cracking and high embrittlement temperature range (HTBR). Analysis of results allowed for evaluation of hot cracking structural mechanism of welded joints Inconel 625.
