4. In which of the following welding processes, filler metals only are melted at temperatures above 450°C?

(a) Brazing (b) Soldering (c) Cold Welding (d) SMAW

5. Which of the following is involved in friction welding process:

(a) Heat (b) Pressure (c) Both of them (d) None of them

6. In resistance welding, the required energy is generated by chemical reactions

(a) True (b) False

Solutions

Expert Solution

1. (a) Residual stresses

Internal stresses or residual stresses sometimes formed in base metal due to removing restraints given to welds by fixed components surrounding it.

2. (d) Hot Shots

3.(c) Cold Welding

Solid state welding is a group of welding processes which produces coalescence at temperatures essentially below the melting point of the base materials being joined, without the addition of brazing filler metal. Pressure may or may not be used.

4. (a) Brazing

It is a joining process using filler metal above 450^oC.

5. (b) Pressure

6. (b) False

The heat is generated by resistance offered by the path to the passing current in the resistance welding.
