What is Cap Pass in Welding?
The final pass of a weld joint is called the cap pass. This pass is used to cover the entire weld joint with a layer of weld metal, providing protection against oxidation and contamination. The cap pass is also used to create a smooth, aesthetically pleasing finish on the weld joint.
What are the passes of weld?
The passes of the weld are the different layers of weld metal that are deposited during welding. Each pass serves a specific purpose, and the order in which they are deposited is very important.
- The first pass, called the root pass, is used to establish the initial penetration of the weld joint.
- The second pass, called the hot pass, is used to increase penetration and to start filling the weld joint.
- The third pass, called the cap pass, is used to cover the entire weld joint with a layer of weld metal.
How do you weld fill and cap passes?
