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.
What type of welding can we use LPG ?
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
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.

Gas pressures and flow rates are typically determined based on the type of material being welded, the welding process, and the size of the weld joint. For example, when welding aluminum, higher gas flow rates and pressures may be required compared to welding steel due to its higher thermal conductivity. It is important to consult welding procedure specifications and guidelines provided by the welding equipment manufacturer to determine the appropriate gas settings for different materials.
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.
