Welding a carrier floor

[Lynn Eades]

Hi Guys. I am welding patches full length of the floor. The rear patch is cut from a piece of old floor (only about 60mm wide) that goes from the cam plate hole to the back. The rest is mild steel.
I found that the mig welds just cracked with a little bit of pressure from a cresent spanner, so i looked through my rod selection and found some "Hi-ten 7 rods. (Phillips rods)
Description in photo. I have tacked it and stitched it and welded both sides and sice the photo have welded the mild steel strip on one side. It seems to be going ok.
BTW, this floor (Canadian MkI U.C.)is approximately 3.9mm thick. this equates to about 0.153 inches which on the gauge scale is between 22g. and 23g.
10 gauge is 4.91mm- way heavier. Maybe later carriers had thicker floors? We've only ever had early ones here. Highest numbers in the 53xxx range.
First time my pictures haven't posted like I wanted them to.
