Hello folks, I believe this topic has been discussed before, but not necessarily with a pictorial to accompany it. The other day the "kids" over in the diesel shop at our school decided to modify an intake manifold on one of their diesel engine trainers. Hence, the weld shop then becomes the rescuer. They busted a pretty good section out of one of the mounting hole passages. After looking it over I decided to use an old trick that was passed onto me by an "old timer", after some cleaning and prep. work, I inserted a stainless steel bolt into the hole and used it for a "form" to shape and maintain the passage while welding. I let them complete the job by drilling the hole back to size and concentricity and then spot-facing the repaired side. Here are a few pics to detail the process. Best regards, Allan

Slick job man,I'll have to remember that one.Did you use 4043 or 5356?
Parent - - By aevald (*****) Date 10-07-2010 15:24
Hello Ringo, different folks have different trains of thought about which filler, in this case I used 5356 because it is slightly "harder" in the as welded state. 4043 could be used just as successfully IMHO. Best regards, Allan

I hear ya.I've had mixed results with welding cast.The first pass usually has alot of porosity,which I grind flush,then the rest usually goes pretty good.Nice job on your part.

Great work Allan and another trick to put down in the black book. I see a coffee cup in the background of that last pic, was there an inspector nearby?  chuckle. re: cactus's bar joke today.

No up-ten, just a welding instructor, you know how we are! Unfortunately, nobody offered to buy me lunch. Best regards, Allan

Good job Allen    that is one of those "slick as greased owl s**t" tricks.   It might be worth repeating that you used an SS bolt....do not try this with galvanized or cadmium coated bolts!
Parent - - By welderbrent (*****) Date 10-08-2010 22:10
Another great idea Allan.

I've used a lot of brass and copper round pieces to weld back broken areas of steel heavy equipment parts.  Had not considered using SS on Alum.

Have a Great Day,  Brent

I like it!

That's using the "ol noggin."
