welding is a process which joins two dissimilar metals........ Actually it is more than that. Welding is a process that involves the application of heat to either add more material or join pcs. together. It is not used just for metals (dissimilar or not) but glass, plastics and more. The pcs. to be welded must melt in order for it to be called welding. Soldering, silver soldering, and brazing are comparable to glueing.

What is crown mean in welding?
In welding, the term "crown" refers to the highest point or the raised surface of a weld bead. It is an important aspect of weld appearance and quality, as a well-defined crown indicates proper fusion and shape. The crown can affect the strength and performance of the weld joint, so it is crucial for welders to achieve the correct crown profile during the welding process.

What does 2g welding position mean?
The 2G welding position refers to a horizontal groove weld position where the welding is performed on a horizontal surface, with the weld bead being positioned in the horizontal plane. In this position, the workpieces are typically oriented in a flat position, allowing for easier access and control during the welding process. This position is commonly used for welding pipelines and structural elements. It is one of the positions defined by the American Welding Society (AWS) in their classification system for welding positions.

How is the welding operation stopped when the arc welding is stopped?
The welding operation is stopped by moving the welding torch away from the workpiece to break the electrical circuit and extinguish the welding arc. Additionally, turning off the welding power source or releasing the welding trigger can also stop the welding operation.
What type of welding machine use in spot welding or resistance welding?
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
What is cs welding?
CS Welding is known as Carbon Steel welding that is more beneficial and easy to use for welding purpose.

What are welding electrodes used for?
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.
