The basic principle of arc welding involves creating an electric arc between the welding electrode and the workpiece. This arc creates a high-temperature flame, which melts the metal at the welding joint. The melted metal fuses together to form a weld when it cools and solidifies.

Metal Arc Welding is a welding process that uses an electric arc to generate heat to melt and join metal parts. A consumable electrode made of metal is used to form the arc and provide filler material for the weld. This process is also known as "stick welding."

Arc welding is a process of joining metals by heating them, which then cools to form a strong bond. An electric arc is created between a consumable electrode and the metal workpiece to produce the heat needed for welding. Different types of Arc welding are as follows: 
1. Stick welding (SMAW):
2. MIG welding (GMAW): 
3. TIG welding (GTAW): 
4. Flux-cored arc welding (FCAW):
5. Submerged arc welding (SAW): 

Arc welding is used for a variety of applications, including welding metals like steel, stainless steel, aluminum, and others, for purposes such as fabrication, repair, and construction.

Welding of high-strength, high-temperature alloys, such as Inconel and stainless steel. Welding of reactive metals, such as titanium and zirconium. Welding of dissimilar metals, such as aluminum and steel. Repair and restoration of precious metal objects, such as gold and silver jewelry.
