I agree with jcc and others about it being repaired before
It looks real thin on the area where it cracked and if you have it welded I'd build up this area a little bit more so you have some wall thickness.

Also I'd check into that stud being crooked. Find out why it is or what's causing it to be crooked. Could possibly be a crooked spot face where your washer sits underneath and should be remachined to it's square and pulls on the stud straight. May help eleviate some future problems with it cracking again.
