BASIC WELDING TRANSMIG 2RT SECTION 4: BASIC WELDING GUIDE Shielding Gas (Optional) Molten Metal Slag 4.01 MIG (GMAW/FCAW) Basic Welding Technique GAS METAL ARC WELDING (GMAW): 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.
TRANSMIG 2RT BASIC WELDING Travel Speed The speed at which the molten pool travels influences the width of the weld and penetration of the welding run. MIG Welding (GMAW) Variables Most of the welding done by all processes is on carbon steel. The items below describe the welding variables in short-arc welding of 0.6mm to 6.4mm mild sheet or plate. The applied techniques and end results in the GMAW process are controlled by these variables.
BASIC WELDING TRANSMIG 2RT Establishing the Arc and Making Weld Beads Gas Nozzle Before attempting to weld on a finished piece of work, it is recommended that practice welds be made on a sample metal of the same material as that of the finished piece. Contact Tip (Tube) Tip to Work Distance Electrode Wire Actual Stick-out The easiest welding procedure for the beginner to experiment with MIG welding is the flat position. The equipment is capable of flat, vertical and overhead positions.
TRANSMIG 2RT BASIC WELDING Electrode Wire Size Selection The choice of Electrode wire size and shielding gas used depends on the following • Thickness of the metal to be welded • Type of joint • Capacity of the wire feed unit and Power Source • The amount of penetration required • The deposition rate required • The bead profile desired • The position of welding • Cost of the wire 4.
BASIC WELDING TRANSMIG 2RT Problem 2 - Inconsistent Wire Feed ! WARNING Disengage the feed roll when testing for gas flow by ear. Wire feeding problems can be reduced by checking the following points. FAULT CAUSE 1 Feed roller driven by motor in the cabinet slipped. Wire spool brake is too tight. 2 Wire spool unwound and tangled. Wire spool brake is too loose. 3 Worn or incorrect feed roller size A Use a feed roller matched to the size you are welding. B Replace feed roller if worn.
TRANSMIG 2RT BASIC WELDING Basic MIG (GMAW/FCAW) Welding Troubleshooting FAULT 1 Undercut CAUSE REMEDY A Welding arc voltage too high. A Decrease voltage or increase the wire feed speed. B Incorrect MIG Torch angle B Adjust angle. 2 Lack of penetration C Excessive heat input C Increase the MIG Torch travel speed and/or decrease welding current by decreasing the voltage or decreasing the wire feed speed.
PROBLEMS/SERVICE TRANSMIG 2RT SECTION 5: ROUTINE SERVICE REQUIREMENTS 5.01 Cleaning the Welding Power Source Warning! Disconnect input power before maintaining. Maintain more often if used under severe conditions Each Use Visual check of torch Consumable parts Visual check of regulator and pressure Weekly Visually inspect the torch body and consumables Visually inspect the cables and leads.
TRANSMIG 2RT PROBLEMS/SERVICE 5.02 Cleaning the Feed Rolls Clean the grooves in the drive rolls frequently. This can be done by using a small wire brush. Also wipe off, or clean the grooves on the upper feed roll. After cleaning, tighten the feed roll retaining knobs. CAUTION Do not use compressed air to clean the Welding Power Source. Compressed air can force metal particles to lodge between live electrical parts and earthed metal parts within the Welding Power Source.
