  • Page 28 GMAW/FCAW Basic Welding Technique Two different welding processes are covered in this section (GMAW and FCAW), with the intention of providing the very basic concepts in using the MIG mode of welding, where a welding gun is hand held, and the electrode (welding wire) is fed into a weld puddle, and the arc is shielded by an inert welding grade shielding gas or inert welding grade shielding gas mixture.
  • Page 29 situation it is recommended to open the cylinder valve, set the flow rate to 8-10L/min, close the cylinder valve and check after a minimum of 15minutes. [5] If there is a gas loss then check all connectors and clamps for leakage by brushing or spraying with soapy water, bubbles will appear at the leakage point.

  • Page 30: Basic Mig Welding

    For practicing MIG welding, secure some pieces of 1.5mm or 2.0mm mild steel plate 150X 150mm. Use 0.8mm flux cored gas less wire or a solid wire with shielding gas. 3.3 Basic MIG Welding Good weld quality and weld profile depends on gun angle, direction of travel, electrode extension (stick out), travel speed, thickness of base metal, wire feed speed (amperage) and arc voltage.
  • Page 31 Travel angle is the right to left angle relative to the direction of welding. A travel angle of 5°- 15° is ideal and produces a good level of control over the weld pool. A travel angle greater that 20° will give an unstable arc condition with poor weld metal transfer, less penetration, high levels of spatter, poor gas shield and poor quality finished weld.

  • Page 32: Travel Speed

    3.4 Travel Speed Travel speed is the rate that the gun is moved along the weld joint and is usually measured in mm per minute. Travel speeds can vary depending on conditions and the welders skill and is limited to the welders ability to control the weld pool.
