Reply to "GT5 flare installation durability question?"

I think the term for that type of weld is a scab weld because it looks like a wound scab.

I'm not trying to be critical. I am just trying to share information. I'm not trying to be the quintisential expert.

Some of these are just preferences I suppose. There is no right and no wrong way.
I would prefer to stay away from the scab weld on sheet metal.

On welds that long there is a tremendous amount of grinding to just get them flush. Now in order to make them invisable, they need to be below the surface of the sheet metal so you can fill them.

I tend to remove to much metal from the sheet while grinding and tend to overheat it and make it too thin. To me that is self defeating. I don't see the point of it. It will crack through the weld in the future or dimble very easy in thinner sheet metal.

I have never been able to do that well at all. If they are beneath the surface, then you have ground them off, because a scab weld sits on the surface.

Even if you are successful, you are talking about weld thicknesses measured in thousands of an inch.

No plumber here Ron. I said I should have been.
