Warpage is a fact of life my friends. Especially if the steel is oil hardening. When you take a piece of steel and go from non magnetic to oil quench in seconds, it's gonna warp. Thats just what it does. The longer the blade, the more it's gonna warp. I don't buy the "weakening at the weld" theory. If one knows what he's doing, a weld can be stronger than the existing steel. It's like silver soldering. Take two pieces of steel, silver solder them in a lap joint and pull it apart in a press. If done correctly, the steel will break, not the solder joint.
I surface grind all my blades to within .0005 before heat treat. All my blades go to professional heat treat. Air or oil harden. I have not had one come back without at least .002 worth of warpage in it. Shim it, and grind it flat. I learned a lesson, grind a hardened blade flat. Don't try to bend it. Good luck to all.
