Looking at the possibility of welding a 700 gallon Hydrogen Peroxide vessel fabricated from 3/16" thick 1188 grade Al. Need to weld/attach two separate tubing/flange configurations: 2" sch 10,
1188 gr. tubing to the vessel. Welding would be in the Overhead position, field welded! Do I dare to GTAW the joint....maybe .040 Zirconiated Tungsten? 5-40 amps?Considering the annealing point is 650F and the melt temp of the wire is
1150+F seems to me to be a ballsy move to TIG it........beside GTAW, I can't think of a practical process to use???? Brazing a low temp solder would likely to warp/collapse the tubing and/or the vessel wall? Any thoughts?respectfully, Harp CWI/CWE
