yes you need to preheat the part

you will need to bevel the crack out alittle and then weld it you will need to also weld it in three passes just like welding a main joint one root pass then two filler passes one beside the other

but the most important part is you have to ping the weld (hit it with a chipping hammer or a center punch) all over the weld also LET IT AIR COOL DONT cool it off with anything or it will crack.

when you ping it then just let it sit untill it cools off on its own.
