The wheelchair shop where I work part-time has a power wheelchair that must be cut down in width. The seat frame to be modified is made of some unknown grade of SS 1" square tube.
I planm to section it to reduce the width. This involves removing either
2" or 3" (depends on a scheduled measurement of the prospective user by our fitters) from each side and welding it back together.Is there a way to identify the SS material of the tubes? What electrode would be best if we can't identify the material? IOW, what's the best choice for use on _any_ SS? (assuming there even is such a thing)
I looked at Lincoln's site and there are a lot of different types of SS electrode listed. Managed to get myself even more confused than usual.
The frame is also powder-coated. I plan to grind that off at the welds of course, but does that present any special issues I should address?
Thanks, John
