Flux Core Mig Welding Sheet Metal

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

Flux core mig welding sheet metal.

In this video i show you how to create better flux core welds with some of the things i ha. How to weld steel with a flux cored welder. Short bursts or tacks will help. It is essential that you are already familiar with working with metal such as cutting it and are aware of the safety.

Self shielded flux cored welding differs from mig welding in that it doesn t require an external shielding gas such as carbon dioxide or argon to protect the weld pool from contamination. Flux core was definitely quite discouraging for me when i started. Basic guide to flux cored arc welding. For this demonstration i ve chosen to keep it fairly simple and make a 2 x 2 x 2 container out of sheet metal.

Users report low spatter from this self shielding flux core wire and high praise for its bead appearance. 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. Tig welding sheet metal. Therefore i will need 5 2 x 2 squares in order to complete my project.

Forget the larger 1 8 inch tungsten electrode and use a smaller one. Metal thickness amperage settings. When welding mild steel a good rule of thumb is to set the amperage level at 1 amp for every 0 001 of thickness. But mig would be easier for a beginner.

Hello and welcome to the slo makerspace guide to flux cored arc welding. Self shielded flux cored welding is a wire welding process in which a continuous hollow wire electrode is fed through the welding gun into the weld joint. To weld sheet metal with solid wires use electrode positive ep or reverse polarity. The settings for flux core wire and non ferrous metals will be completely different.

So if you are welding 12 gauge mild steel with a thickness of 0 100 you would set the machine at 100 amps. While wire feed welding sheet metal go for short bursts of welding instead of a going on a long bead. Don t attempt to weld thin materials like sheet metal with flux cored wires which put more heat into the base metal.
