Some believe flux core can weld Aluminum, but there is no flux core wire for Aluminum welding. Flux core is also able to weld some forms of nickel alloy. If you need to weld through galvanized steel then flux core welding is your choice. That galvanized item may not be so easily taken into a workshop and welded, as it may be a small part of a larger object that is difficult to move. Where there is galvanization we’re normally talking about an object that needs to live outdoors, like a gate, or pipe or fencing and so galvanization has been used to protect the steel.

There are other forms of welding that demand the galvanization is grinded off first. Flux core welding is a form of welding that allows the welding of steel with galvanization on. Use Flux Core Welding When Welding Galvanized Steel You can weld 1/2 inch thick metal with a single pass with flux core, compared to MIG welding where the same welder, with the same level of voltage output would only be able to weld 1/4 inch with a single pass. Self shielded flux core welding is pretty good too.

Gas shielded flux core welding in particular is great for thick metal penetration. This is why this method of welding has been used in the structural steels industry. Flux Core welding is known for its good penetration thick gauges of metal. Flux Core Welding Is Used For Thick Metal Paint and oil should be removed – get rid of as much as you can – otherwise when welding in the rough choose flux core welding. This is quite not the case with flux core welding.īut where you do have a broken tractor or machine part or gate that can’t be easily taken into a workshop situation and scrupulously cleaned then flux core welding is the choice. Metal that has any rust or mill scale or galvanization must be cleaned first before MIG and TIG welding. Is Used Where The Metal Can’t Be Easily Pre-Cleaned A good example of flux core welding outdoors.įarm Welding Repair. This 3 minute 27 second video from Miller Welders shows flux core welding on a farm part – a heavy duty trailer hitch. YouTube Video Showing A Farm Repair Outdoors Erecting wind barriers can help but if they are not positioned correctly then a bad weld will result.įlux Core Welding is the choice when you need to fix a broken tractor or machine part out in the middle of a windy field. The separate shielding gas as used in MIG welding to protect the weld would just be blown away with the wind. Hot molten metal when subjected to the air we breathe without any form of protection produces welds that are poor and fail. Because the self shielding flux core welding wire produces shielding gas at the point of the weld to protect the melted metals from the atmosphere. Even quite high wind doesn’t affect flux core welding. Self Shielded Flux Core Arc Welding Is Preferred For Welding Outdoors Where taking insufficient rods with you means that you have to stop welding and go get some more.Ī flux core only welder can be lighter and easier to carry when welding in difficult to access places – I read of one person using his flux core welder up a ladder – something that would be more difficult with other forms of welding. There are no separate rods of welding wire to take to your welding site as in stick welding. There is no need to worry about transporting a separate cylinder of high pressure gas as well.Īnyone who has transported a tank of gas knows they are heavy, awkward to lift and need to be transported with care.Īs the gas inside is under pressure and Argon gas can silently suffocate if leaked within an enclosed space like the inside of a car or the cab of a truck. Flux Core Welding Is Used Where Portability Os Importantīecause when you are flux core welding, as long as you have the means of generating power at the welding site and of course your safety equipment.Īll you need to take with you is your flux core welder and have it installed with some appropriate flux core welding wire.
