Down hill welding
Typically when i down hill weld i crank the heat up more. I have welded heavy truck frames (3/8-1/2 inch thick)down hill but with the heat cranked nice n hot. One particular truck I shortened the frame on, had a garbage truck body mounted on it and carried regularly 30 to 40 thousand lbs of trash daily and was even involved in a roll over once with no problems with the welded frame! (And thats even without sleeving or plating the frame!)So my point, is that done correctly,down hill welding can be just as strong and dependable as an uphill weld.
