How to weld thin sheet metal with flux core.

It s not ideal to use flux cored processes for very thin below 20 gauge materials. But keep in mind that thinner material like sheet metal should not be welded with flux cored wires. 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. For thin sheet metal use argon 2 oxygen shielding gas as this will further reduce the arc heat input.

This guide will teach you how to weld steel with a flux core welder. Fcaw shouldn t be used on materials thinner than 3 32 or 12 gauge. Instead this self shielded flux cored process is ideal for welding dense portions of steel materials. I use the method flux core to weld thin metals as the cabinets and steel wardrobes are made from thin metals.

Https amzn to 37bevj1 while wire feed welding sheet metal go for short bursts of welding instead of a going on a long bead. It is essential that you are already familiar with working with metal such as cutting it and are aware of the safety. 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.

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