Gas Metal Arc Welding (GMAW) Position of MIG Torch (Fig 1-3) This process, also known as MIG welding, CO2 welding, Micro Wire Welding, short arc welding, dip transfer welding, wire welding etc., is an electric arc welding process which fuses together the parts to be welded by heating them with an arc between a solid continuous, consumable electrode and the work.

FORCE 200MST MIG Welding When there is a gas problem the result is usually porosity within the weld metal. Porosity always Troubleshooting stems from some contaminant within the molten weld pool which is in the process of escaping during solidification of the molten metal. The general approach to fix Gas Metal Arc Welding (GMAW) problems is to start at the wire spool then Contaminants range from no gas around the...

FORCE 200MST MMA Welding Techniques Corner Weld - A Word for Beginners (Fig 1-19g) For those who have not yet done any welding, the simplest way to commence is to run beads on a piece of scrap plate. Use mild steel plate about 6.0mm thick and a 3.2mm electrode.

FORCE 200MST Heavy plate will require several runs to complete the joint. After completing the first run, chip the Multi-Runs in HV Fillet Weld (Fig 1-24) slag out and clean the weld with a wire brush. It is important to do this to prevent slag being trapped by the second run.

TIG Basic Welding Guide TIG Welding is a fusion procedure that uses an electric ARC created between an infusible tungsten electrode and base material to be welded. For TIG welding an inert gas must be used (Argon) which protects the welding bead. If filling material is used, it is made up of rods suitable to the material to be welded (steel, stainless steel, copper etc).
