Flux Cored Mig Welding Sheet Metal

To weld sheet metal with solid wires use electrode positive ep or reverse polarity.

Flux cored mig welding sheet metal. How to weld steel with a flux cored welder. Don t attempt to weld thin materials like sheet metal with flux cored wires which put more heat into the base metal. The settings for flux core wire and non ferrous metals will be completely different. Users report low spatter from this self shielding flux core wire and high praise for its bead appearance.

For this demonstration i ve chosen to keep it fairly simple and make a 2 x 2 x 2 container out of sheet metal. When welding mild steel a good rule of thumb is to set the amperage level at 1 amp for every 0 001 of thickness. This guide will teach you how to weld steel with a flux core welder. Hello and welcome to the slo makerspace guide to flux cored arc welding.

Therefore i will need 5 2 x 2 squares in order to complete my project. 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. Forget the larger 1 8 inch tungsten electrode and use a smaller one. 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.

It is essential that you are already familiar with working with metal such as cutting it and are aware of the safety. So if you are welding 12 gauge mild steel with a thickness of 0 100 you would set the machine at 100 amps. Flux core was definitely quite discouraging for me when i started.
