CWIC / Stanweld,
Thanks,I appreciate your replies. In reference to your comments, I do suspect that part geometry does contribute signifigantly. As noted, we are welding in areas of transition from thick to thin. In some cases, .750" to .080". We have also experienced some hot...
Simllarly, can anyone recommend a set of proven GTAW-P parameters for welding I-718 alloy castings? I am experiencing hot cracking prior to PWHT. The castings are in the homonegized condition prior to weld assureing the most favorible condition. I have tried lower amperage and lower interpass...
Could anyone recommened a proven set of parameters (GTAW) to prevent hot cracking when welding I-718 alloy castings? We have experimented with pulse vs. straight polarity and used lower amperage and lower interpass tempuratures. The castings are in the homogenized condition prior to weld so they...
