How To Weld Thin Sheet Metal With Flux Core

These types of wires put more heat on the base metal and can result in distortion and unwanted mistakes.

How to weld thin sheet metal with flux core. This guide will teach you how to weld steel with a flux core welder. For thin sheet metal use argon 2 oxygen shielding gas as this will further reduce the arc heat input. I would advise against using pure co2 for thin gauge materials. Lastly do not try to use flux cored wires for thin metal sheets as they pass more heat to the base metal.

I use the method flux core to weld thin metals as the cabinets and steel wardrobes are made from thin metals. For sheet metal i use ine welding wire and it is just as good as their flux cored wire if you want you can grab one here. It s important to know that flux core arc welding fcaw is different from shielded metal arc welding smaw and mig welding techniques. Https amzn to 37bevj1 while wire feed welding sheet metal go for short bursts of welding instead of a going on a long bead.

Flux cored arc welding fcaw this is another option for welding a 20 gauge metal sheet but does not work as well as the mig. Fcaw shouldn t be used on materials thinner than 3 32 or 12 gauge. How to weld steel with a flux cored welder. 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.

Instead this self shielded flux cored process is ideal for welding dense portions of steel materials. It s not ideal to use flux cored processes for very thin below 20 gauge materials.
