The general idea is to Weld the crack after grooving it to get more adhesion & Penetration, then build up a "scab" over the crack and say 8mm either side that can be ground down if required. This gives the strength required, its not an ideal solution, this is true, but has worked for me in the past and is a solution if a part cannot be sourced straight away.

I agree Martyn, but since the kick"clamp" is so thinn, I think the heat created by the welding it self will spread so fast that pre-heating is not really needed.
