tips for welding cracked exhaust manifolds?

[Bob]

Depending on the rod you get. You can heat it with an oxy torch first if
you use a nickel rod, but there are rods now that you dont have to heat
it that work great. But whatever you do, dont forge to drill both ends
of the crack to prevent it from walking!
