Exhaust manifold weld

Hello, I am in need of having a cast iron exhaust manifold welded...need to reattach the downtube(flange).

Is this an easy job at a weld shop, how good will this hold? I am looking to attach a turbo and this should help, the manifold will not need to support the weight of the turbo.

Mr-Muldoon.....hope your 4/july weekend is going good.I have been doing yard work/got a round of golf in and the kids came over kicked my butt on the play station 2. But who cares about all of that. Today I was replacing the exhaust manifold gaskets on my 73-250 for the first time since I have had the truck ( a year give or take) and found the weld that I didnt know was there had failed. Take a look at the pictures on my user page. Your call...... Depending on when you look these pictures up they may or may not be posted yet. It takes a little while so i understand.

A GOOD welder can do it. It's a tedious process involving alot of prep time to the damaged area along with preheating, stress relieving, proper post-welding cool down and such. A filler metal that has Nickel in it MUST be used, unless it is brazed. If the base is welded with Ni-rod, you should see good results. Find a good shop that knows how to properly weld cast iron and you should be good to go.

Agreed. I made a passenger dual exhaust manifold for my 292 years ago out of 2 different stockers just by welding the 2 together. Find a good welder and it will hold.
