I've some hot rolled flat bar stock stick welded (6011 rod, 1/2 x 4 & 1/2 x 2) into an unequal angle shape maybe 2 feet long and need to drill the welded areas. I figure it is probably hardened some and should be normalized or annealed first so I don't break the bit. I was thinking I'd try putting it in the gas grill for a while, then spot heat the welded area with a map torch and then leave it in the grill for a while longer.

Is this a viable plan? If so how hot and how long should I go with the grill ... with the torch ...?

Any other suggestions?
I'm a novice at this sort of thing so any help would be greatly appreciated

Thanks

Have you tried drilling as it is? I would try first before going on.

I'll give it a try over the weekend, but with my luck I'll probably end up with a bit busted in the hole.

Well worked out ok.
