Welding a frame up....... at a notable stress point - obviously be noted by a tester,would it be 'allowed' & does the condition of the welds especially count.?.
A good weld may not be found by some M.O.T testers ! I've welded my typhoon frame and nothings ever been said, suppose it's what's been welded.
That's the frame with injury in a dubious location,it's sound apart from that 1 spot - not bad considering it's approaching 40,000 miles..
