• TIG (Tungsten Inert Gas) welding uses a tungsten electrode and filler metal to join metal.

• Stick welding uses a consumable electrode coated in flux to join metal.

• Flux-Cored welding uses a wire electrode with a flux core to join metal.

Q3. What is submerged arc welding process?
Ans. 
Submerged arc welding is a process where an arc is maintained between a consumable electrode and the workpiece under a blanket of granular flux.

Q4. Procedure of rectification for defected welding joints?
Ans. 
Defected welding joints can be rectified through a process of cutting, grinding, and rewelding.
