MIG Welding Carbon Steel - Joint Set-UP, Electrodes and a36 cbarbon content Argon arc welding
Joint preparation for carbon steel is the same as if you are stick weldingwith an E7018. The weld area needs to be free of oils, paints, heavy rust, and in most cases mill scale. Ideally you want to grind the joint area back about 1 ½ of an inch to clean metal. All joints must be braced to avoid distortion from weld shrinkage. When it comes to welding heavy plate you will need to brace your joints more than thinner metals. The shrinkage from multi pass welds will distort the joint to the point where it is no longer square.See more on gowelding.orgHow to Weld EN24/ AISI 4340 and EN 24/4340 with A36 steelIf arc air gouging is the preparation method to be used, then preheating before preparation must be exercised.
