1. What are the units of pressure and forces? 2. State the types of welding processes carried out in manufacturing industries. 3. State brief description about the welding processes.

Question

Accepted Answer

1. Pressure is measured in units such as Pascal, psi, or bar. Forces are measured in units such as Newton or pound-force.

Pressure units: Pascal (Pa), psi (pound per square inch), bar
Force units: Newton (N), pound-force (lbf)
Example: Pressure of a car tire is typically measured in psi
Example: Force required to lift an object is measured in Newton
