Welding of Gr. 5 and/or A325 Bolt
Welding of Gr. 5 and/or A325 Bolt
(OP)
I have a project where I need to bolt a fixture to a plate. I have to weld a gr.5 or A325 bolt head to the back side of the plate with the bolt passing thru the plate. Then weld the plate to the top of a HSS column.
the bolt will see a 5000 lbs working load in shear.
Will the weld affect the integrity of the bolt?

The ASTM A325 bolt is quenched and tempered. Welding it will produce untempered martensite in the heat affected zone. If the weld is around the head of the bolt, the heat affected zone may extend to the shank of the bolt and result in a brittleness just where you don't want it, i.e., under the head of the bolt.
