47-55.1 Welding the top and bottom half of the cab together

[Thadious]

So, after sandblasting my cab with crushed glass grit, I've started to notice little pinholes and more showing up and growing around the corner window and below the center back window. Deciding that I wasn't going to do all this work to have the 'unknown' of that back seam and pinholes haunting me, I sourced a second inside cab section, cut it out, sandblasted and cleaned it up.

So, today I cut out the inside cab of my project, and I'm glad I did!

There were far more pinholes than I expected and the joint half of the two sections was heavily rusted out.

My intention is to brace the cab seam from the outside to prevent any movement, layout and cut a new seam section from 14ga steel, then bit by bit cut out the original seam, weld the top and bottom halves together as close to the outside of the seam as possible and slowly work my way around, completing the weld fully. (This is largely due to the common complaint of the seam rusting over the years and messing up paint jobs and continually corroding.

Once the seam has been fully welded, retrace the weld line onto the new brace, cut and weld the new brace section in then install the "new" inner cab, and finally remove the outer braces and clean up the welds.

Anyone have any thoughts or experiences?

Cheers!
Ted.
