ER5056, ER5356, ER4043: These wires are commonly used when welding aluminum.It contains manganese deoxidizers and silicone and is commonly used with 100% carbon dioxide or 75/25 argon/carbon dioxide. ER70S-3: This is another wire mostly used for welding mild steel.Here is a list of other frequently used MIG solid wires: The ER70S-6 wire is frequently used with 100% carbon dioxide or 75/25 argon/carbon dioxide. For this particular wire, the number 6 means that the wire contains more deoxidizers, allowing you to weld steel that’s rusty or dirty 6: This number, which occasionally also contains a letter, represents the chemical additives inside the wire, which may affect your machine’s polarity settings.S: This means that the wire in question is solid.70: This number represents the minimum tensile strength of the weld metal, displayed in pounds per square inch (PSI), which is multiplied by 1,000.One of the most common MIG wires for mild steel has a classification code ER70S-6, which indicates the following: Solid MIG wires are classified under the code AWS A5.18. The American Welding Society provides a classification system for different MIG solid wires, and each wire has different codes. Recommended wire sizes based on the thickness of the welded material – Click here for full size image However, when welding thin steel, you’ll probably need a solid MIG wire with a smaller diameter, either 0.24 or 0.30 inches.īelow is a full chart of recommended wire sizes based on the thickness of the welded material: Instead, you need to choose the wire size according to the thickness of the metal you’re welding.įor example, when welding sheet metal, the most common wire sizes are 0.35 and 0.45 inches. MIG welding has multiple wire sizes because you can’t weld materials of different thicknesses with just one size of wire. Not the best wire option for outdoor conditions.Requires a shielding gas to protect the weld.An excellent choice for welding aluminum.Better wire option for welding thin stock.Minimal spatter/ less need for cleaning after welding.However, solid wires may not be the best option for every welding task as they don’t perform well outdoors and are unsuitable for MIG welding cast iron and thick stock. They create good, sturdy welds while producing little spatter and no slag, making MIG welding a neat process. Solid MIG wires come in a variety of diameters and are more affordable than flux-cored wires. Typically, these wires are mild steel-plated with copper - an excellent choice for welding thin stock and materials such as aluminum. The shielding gas you need for MIG depends on the material you’re welding, although carbon dioxide and 75% argon are the standard go-to options. MIG welders use “standard” solid wires that require a shielding gas to protect the weld puddle and prevent atmospheric contamination. There are two main types of MIG wires: solid wire and flux-cored wire. So, per the example above the number of inches of. Once we have inches per pound all we need to do is multiply this number by the number of pounds per package. The density of aluminum is 0.098lb/cu-in so please be careful to use the right density. The density of steel and stainless steel are pretty close (0.283lb/cu-in and 0.289lb/cu-in respectively). What we are calculating is the volume of material and then multiplying it by the density of that material to arrive to our answers. Weight of package (weight of filler only).Filler metal type (carbon steel, stainless steel or aluminum).The calculation is simple, but we need to know the following: Please note, these calculations are for solid wires only and do not apply to flux-cored or metal-cored wires. You can also keep reading below to see how we can calculate this for any diameter, and not just the common ones such as.
