In contrast with what is used in MIG welding, where shielding gas must be transported everywhere for proper utilization, the self-shield produces its protection gases at the point of welds. When it comes to flux core welding, you will find two types of wire: More commonly called “shielding” and mixtures of Argon/CO2 or Ar/CO2/He can all work depending on what type of metal(s) is being welded stainless steel uses mainly helium mixed with some CO2 & Argon. The hose supplies the welder with its respective gas, and there are several gases used for protection in MIG welding: argon, carbon dioxide (CO2), This means purchasing a separate pressure tank connected to either flow meter or regulator, attached via a running hose. When comparing the two welding processes, one difference you will come across is that shielding gas is necessary when using a MIG wire. But, some differences might come up when doing one over the other. These metals melt at much lower temperatures than steel, so they do not affect base materials when used properly.īoth of these welding processes will give you excellent grounding. It’s like an outer coating for SMAW (stick) electrode!įor MIG, there are two options: either using argon gas or adding another filler metal in the form of short rods, which we will call stick electrodes. This allows operators to weld outdoors where it can be windy. The main difference between flux-cored arc welding and MIG welding is how each process shields itself from oxygen.įCAW gets its shielding from a hollow wire containing flux, similar to “pixy sticks” candy. Inert gas keeps off airborne contaminants from the weld area, making it ideal for non-ferrous and aluminum materials. What Is MIG Welding?Ī wire electrode connects two metals in MIG welding as they pass through the welding gun. Still, it has more impurities than other methods, so proper monitoring systems at hand must be done carefully, and training for each operator. The flux core provides a shield from any of the surrounding atmospheres. It’s an early welding technique and only used in the flux welder, which can also use a MIG set to feed shielding gas or solid gases. What Is Flux Core Welding?įlux core welding is a process denoted by FCAW (Flux Core Arc Welding). Some people prefer flux-core welding, while others swear by MIG.Įveryone has a reason for choosing what they do, but it’s hard to say which is better overall.

Some key points and differences include walking through them one by one to understand when choosing between these two types of methods used while doing manual work with metal materials together as a team effort while trying not to hurt yourself too badly. It also comes down to personal preferences regarding the finish of your weld after that point. Deciding to use Flux Core welding rather than MIG depends on:
