Heat input and Hastelloy

Need more info regarding the thickness of the material, the joint configuration, the method of transfer you're going to use, what position are you going to deposit the weld in, etc.

How about giving us an idea what you were going to use as welding parameters including travel speed, % of Argon & Helium shielding gas, etc. ;) What type of set up are you working to? ;) ;) ;)

Respectfully,
Henry

Btw, Steve, Did you manage to find this .pdf by any chance???

http://www.haynesintl.com/pdf/h2110.pdf

How about this one???

Remember that Maximum interpass temperature is no more than 200 degrees F. during welding. ;)

Hope this helps! ;)

Henry

Thanks Henry that first pdf had it all , the application was a overlay on 25mm A516-70 plate. I ended up using gmawp with 1.2 wire and 25% Helium in Argon most runs were about 160Amps , 27 Volts with around 500-550 travel speed , max interpass temp was 85 C . My calculated heat inputs were well under the maximums indicated in the haynes pdf. Visuals and DP looked good so I just have to wait for mechanicals.

Hi steve!

I'm glad it was helpful... I was just curious... Your increased travel speed than from what was recommended, was it increased to control dilution & distortion?
I could understand if this was the case. ;)

Nice post/info Hank! I saved those in case I ever get back on aircraft and have to run any wire (have not run across it yet ...but)....always helps to be armed with hard data when arguing with the weld engineer.

Who's Hank :) Dilution was always going to be an issue Henry, client spec. required a 3% max Fe , 6mm min thickness and a min 3 layers . I achieved just under the 3% Fe content on the second layer so that worked out well. But more to the point those speeds gave me the correct thickness with by the 3rd layer . An added bonus was It just welded nice at that speed. :)
