Welding Thin Sheet Metal With Flux Core

Since the sheet metal for our container is a fairly thin gauge approx.

Welding thin sheet metal with flux core.

I use the method flux core to weld thin metals as the cabinets and steel wardrobes are made from thin metals. The video is about five and a half minutes long. I found a useful video on youtube that illustrates the flux core welding of galvanized steel. Don t attempt to weld thin materials like sheet metal with flux cored wires which put more heat into the base metal.

Although flux cored welding is more forgiving of dirty metal than mig welding it s still a good idea to clean. Forget the larger 1 8 inch tungsten electrode and use a smaller one. The demonstrator doesn t believe a mig process solid wire and shielding gas can weld galvanized where as plenty of us do.

Youtube flux core welding video. To weld sheet metal with solid wires use electrode positive ep or reverse polarity. Revolution of flux core before 1950 the common welding use for thin metals was shielded metal arc welding smaw in the mid 1950s the development for flux core welding was achieved.
