It uses flux-coated rods and relies on a slag system for shielding against atmospheric contaminants and metal impurities. The stick welding process is the most rugged of all compared processes. Stick Welding or SMAW (Shielded Metal Arc Welding) The welding joint must be perfectly cleaned.Requires a lot of skill that can’t be obtained quickly.Costly equipment (TIG welder, argon gas, etc.).Excellent visibility over the weld pool.TIG is an extremely clean welding process It doesn’t produce smoke, sparks, or molten bits.Excellent choice for welding thin metal.TIG welding allows you to make precise welds.Produces strong welds with beautiful-looking beads.Argon provides a stable, focused arc, while helium achieves deeper penetration. The shielding gas is pure 100% argon or a mixture with helium. You must match the tungsten type with the polarity and the appropriate welded metal to make a quality weld. The tungsten electrodes vary by their principal oxide. You can also weld without a filler wire, which is sometimes advantageous compared to all other arc processes. It uses a shielding gas like MIG, but the filler rod is fed manually into the weld pool. It’s most challenging to learn, and it’s used for critical welds. The TIG welding process is the cleanest of all arc welding processes and produces the highest quality TIG welds. Not recommended for welding thinner than 20 gauge.Requires post welding cleanup because FCAW creates a lot of sparks and molten metal bits that fly all over the welded piece.Requires slag removal after welding and between each pass.The resulting welds from FCAW are not as good-looking as with the MIG welding process.It is dangerous to weld indoors without sufficient ventilation due to released gasses. ![]() It isn’t easy to see the welding pool, requiring more skills from the operator ![]() Flux-cored welding process releases much more smoke than MIG and even stick welding.All MIG welders support the flux core welding process.Flux core wire doesn’t require wire clippers to cut off the tip because it can be broken off by hand.The equipment is more portable than MIG welding equipment.The flux can contain additional deoxidizers allowing you to weld dirtier metal with more impurities. ![]() It provides deeper penetration and faster deposition rate than MIG because the welding current is concentrated on a smaller metal area of the wire cross-section.Requiring no shielding gas, the FCAW is an excellent choice for welding outdoors.However, there are FCAW wires that do require a shielding gas, but those are not typically used in everyday welding. This slag protects the weld pool from atmospheric contamination and uses hydrogen to its advantage, turning it from a contaminating element to a protective factor. ![]()
