How To Weld Thin Sheet Metal With Flux Core

Fcaw shouldn t be used on materials thinner than 3 32 or 12 gauge.

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 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. This guide will teach you how to weld steel with a flux core welder.

I would advise against using pure co2 for thin gauge materials. For thin sheet metal use argon 2 oxygen shielding gas as this will further reduce the arc heat input. It is essential that you are already familiar with working with metal such as cutting it and are aware of the safety. Https amzn to 37bevj1 while wire feed welding sheet metal go for short bursts of welding instead of a going on a long bead.

Instead this self shielded flux cored process is ideal for welding dense portions of steel materials. But keep in mind that thinner material like sheet metal should not be welded with flux cored wires. Lastly do not try to use flux cored wires for thin metal sheets as they pass more heat to the base metal. It s important to know that flux core arc welding fcaw is different from shielded metal arc welding smaw and mig welding techniques.

Use gas shielded mig welding instead of flux core. 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.
