Welding a carrier floor

[RichardT10829]

Pretty much all been covered, I used mig with good argon shielding mix. Weld an inch then move along say 10" before starting the next inch of weld, the aim as already described is to minimise heat soak into the job.

to add another facet to the job, I stretch my welds on long runs such as this....so weld the inch but before it cools flatten the weld with a hammer (dolly will need to be on the other side) this stops the sheet being pulled as the weld shrinks as it cools, in essence you avoid the issues of the two sheets becoming miss aligned and you putting un necessary tension into the sheets.

its a biggie especially welding aluminium, or aircraft skins which are thinner, but personally I advocate irrespective of metal thickness you do it.

best of luck to you buddy.
