What are the basic requirements for arc welding?
All arc welding processes have a few basic requirements for their operation. They must have a safe voltage available that is sufficient for the operator to get the arc started and be maintained. They also require sufficient amperage to provide the heat for melting of the parent metal and filler material.
What are the different types of arc welding machines?
This section introduces some of the most commonly used arc welding processes; which are: manual metal arc welding (MMAW) gas metal arc welding (GMAW) flux cored arc welding (FCAW) submerged arc welding (SAW) gas tungsten arc welding (GTAW). • ο ο ο ο ο • ο ο ο ο ο ο • • • • • Chapter 2 – Electricity and welding machines 32
What is manual metal arc welding?
Manual metal arc welding (MMAW) MMAW is a welding process that creates an electric arc between a hand held, flux-coated, consumable filler wire and the work piece. The arc heat melts the parent metal and filler wire. The flux coating breaks down in the arc to produce a gaseous shield that excludes atmospheric gases from the weld zone.
