![]() Solid MIG wire is not tolerant of contamination of the welding area, so be sure to prepare well, grind off all the galvanizing – two inches either side of the weld. Otherwise 75% Argon and 25% CO2 is another good option for shielding gas. Many use straight carbon dioxide as their shielding gas of choice because it is cheap, though it does produce a lot of spatter. Choose the right kind of solid wire and shielding gas and you can do it. Yes, you can use the MIG process – solid wire and shielding gas. Here are the 16 things to know when flux core welding galvanized steel, made simple. The galvanization is applied to the steel through hot dipping the steel into zinc or shot blasting – called dry galvanization. This oxidization protects the steel even if the steel is scored down to the bare metal – the zinc coating will still protect the metal. Similar to paint it forms a protective barrier between the steel and the air though galvanization goes further by providing electrochemical protection Galvanization is a process which puts a protective zinc coating onto steel although to protect the steel from rusting. You may have seen a scratch in the covering paint and see the galvanization below the paint.Įxample of Galvanized Steel What Is Galvanized Metal? You may well see the tell tale sheen, sparkle in sunlight that gives away the fact that the metal is galvanized. How Can I Tell If The Metal Is Galvanized? Why Does Metal Fume Fever Not Affect Some People? How Bad Is Welding Galvanized Metal For Your Health? After Welding Galvanized Steel With Flux Core Benefits Of Welding Galvanized Steel With Flux Core Wire? What Should I Do If There's A Thick Galvanized Coating? What Do I Mean By A Well Ventilated Area? How Do You Weld Galvanized Steel With Flux Core? What Happens When You Weld Galvanized Steel With Flux Core Wire? How Can I Tell If The Metal Is Galvanized?.Really lets you get things lined up and see what you are doing. By far the best investment I have made in welding equipment, and I have the $49 one from Harbor Freight. Second, buy an auto darkening welding helmet. Keep making small spot welds until you have the joing fully welded. Just little spot welds and jump around to keep the heat down. Two things really made a difference for me.įirst you have to weld in short bursts. I did all of the welding on my 66 Squareback, including repairing the heater channel/rocker and shaving the bump for the front license plate, along with some small holes in the fenders and the doors. I have the cheapest ass flux core welder you can get. ![]() ![]() The only way to weld sheet metal with flux core MIG is to NOT DO IT AT ALL style_emoticons//smokin.gif Get that gas hookup and get a tank of stargon, you'll love it! style_emoticons//wub.gif its like night and day style_emoticons//Dancing.gif Quote: Originally posted by 24 2005, 09:53 PM
