There are different methods to do the welding process, but they all use a power supply that generates the electric arc which will melt the metal at certain points. You can know more about welding services via https://ogis.com.au/services-capabilities/welding-service/
Variations include the following options:
– Shielded metal arc (SMAW). It is one of the most common process used for iron and steel, though it can also be used with aluminum alloys, nickel and copper. It was historically used to build the steel structure and fabrication industry, but today, it has become the main method used in the field of maintenance and repair.
– Gas metal arc (GMAW). It is the primary industrial welding service because of its flexibility, speed and adaptability to robotic automation. Because the gas component, is usually not carried out or in areas where the air is volatile.
– Gas tungsten arc (GTAW). This method can be used on almost any type of metal, but the most commonly used on light metals and stainless steel. Some common applications including bicycles, aircraft and naval equipment.
– Submerged arc (SAW). In this process, the arc is struck beneath a layer of covering flux, which protects the surface from contaminants. Layer covers It also means better working conditions, for a closed arc and almost no smoke is generated. It is commonly used in industrial applications for large products and pressure vessels.
It is one of the oldest and most versatile welding, but in recent years has been used less often for industrial applications. It is mainly used for repair work, such as repairing pipes and tubes. The materials needed for this process are generally inexpensive and simple to use. This process involves the acetylene and oxygen to produce a flame. Fire is not as concentrated as the electric arc, so that the material can cool more slowly.
