Dome panel patching
Dome panel patching
(OP)
Hi all
one side of a triangular dome panel is short in length. If we need to patch up that dome panel to make up for it original length which process is better? MIG welding or riveting? Kindly share your ideas. Thanks in advance.

Is this a large dome with 8 pie segments?
Are there only 8 of these triangles on the whole dome?
What has the manufacturer told you?
Is the material 0.050" thick 3003-H16?
Are the edges of the panels step-bent ( send a picture or diagram )?
You can certainly MIG weld 0.050" thick aluminum - we weld about 1,400 feet every day in our shops. But, it takes good setup, careful control and allowance for expansion and shrinkage, proper equipment, etc. We also TIG weld similar materials but I would not recommend it for a number of reasons.
Not the least of your problems is how your modified panel will meet the API standard for the design loads of 60 psf uniform and 250 pound concentrated not to mention the clause "G.4.2.3.1 Roof panels shall be of one-piece aluminum sheet" and if your customer will accept the repairs.
