There are some smallish mild steel bars and some thin steel plate on top of the red welder. | There are some smallish mild steel bars and some thin steel plate on top of the red welder. | ||
It can be used for practice, the first attempt to weld a bar to a plate resulted in a very poor weld due to inexperience and because the plate melts before the bar gets hot enough. | It can be used for practice, the first attempt to weld a bar to a plate resulted in a very poor weld due to inexperience and because the plate melts before the bar gets hot enough. | ||
MIG welding is not the best method for joining thin material to thick material (brazing or oxy-acetylene welding is better) but you can do it by first building up the thickness of the thin material using stitch welding to avoid "blowing through", then do another run of weld to actually join the two pieces together. | |||
Some acceptable welds have been made joining some thick chain to the end of a steel scaffolding pole. | Some acceptable welds have been made joining some thick chain to the end of a steel scaffolding pole. | ||
Note : practice on thick stuff. Practice even just running a bead along a surface without attempting to make a join. Thin stuff is hardest. | Note : practice on thick stuff. Practice even just running a bead along a surface without attempting to make a join. Thin stuff is hardest. | ||
