I've been tasked with making a pin out of 4140 which is to be welded to formed plate made from A572. The plate is used to hold the pin in place.
The pin material is 1.25 dia and a little over six inches in length, the plate material is .3125 thick. The pin extends past the plate .3125 inch and an all-around .25 fillet weld is used. The plan is to use both a preheat and PWHT on the finished pin.
Weld proceedure and filler material are wide open at this point.
What is the best procedure (preheat temperature, PWHT, etc) considering we would like to maintain as much strength in the pin as possible?
