Welding Chill Plates

Thank you hemmjo. The flattened copper pipe is really useful. If you don't have copper you can get a similar effect using thick aluminium sheet, which sounds odd as you'd expect it to melt at steel welding temperatures. As long as it's thick enough / has some free area for cooling it conducts the heat away before it will melt. On a side note, backing of welds using copper / aluminium isn't allowed in some industries, but I find it's very helpful to improve my amateur welding!
