High frequency stabilized alternating current power supply is the most used GTAW process for aluminum with pure tungsten electrodes.
Welding Electrorodes or Welding Rods are used in arc welding. Arc welding is a special type of welding which uses a welding power supply to create an electric arc between the base material (e.g. steel) and the electrode. The Welding Ectrorodes can be used for all weldable aluminum and mild steel.
A C, with high frequency superimposed, when welding Aluminum. D C straight polarity on almost everything else.
One type of welding is tube welding. Another type if mig welding.
You can do Shielded Metal Arc Welding (stick) with an appropriate electrode. If the machine has a high frequency arc stabilizer then you can also TIG (tungsten inert gas) weld aluminum. Wire feed processes require a DC machine
What type of welding can we use LPG ?
Any technical college will offer some type of welding education. Alabama Southern Community College is just one example. You can use google maps to find a welding program near you.

SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.
it is type of a non ferrous welding process,
