Chuck and others,
What is the high level parameters for annealing the barrels after welding or for pre-heating before welding?
Is it just heating the barrels to ~400F for X number of hours or do you need to just anneal the welded zone area? Does it need to be hotter? I thought the true sense of annealing was getting it up to or close to the critical temp. Are we actually just stress relieving at temps in the 400F range?
Is it just a matter of using an oven to heat the barrels either before welding or after? Or do you use a torch or something else to heat the affected area only?
