Here was one of my recents projects...... braze a fresh water manifold off a tug boat...
The problem..... A crack on one of the bolt flanges. The crack does not go all the way through the piece is still attached.
First I sandblast the area and gouge the sides......
By doing the sides first I can now use a cylinder type carbide bur and open up the crack on the inside without having to worry about breaking the flange completely off.... At the same time I open up the backside of the joints I just brazed, gouging into the filler material I just put in. This will ensure that I have 100% penatration. Then I braze it up......
Looks like hell huh? Wait there's more..... okay time to clean it up...
After cleaning the part I had to braze a layer of filler over the flange ear... when I placed a straight edge across all the flanges the one I brazed was not quite even with the others. Even though there is a gasket enough torque on the flange could cause it to break again. A little bit longer and.......
Another happy customer......
