Which material is used at the negative electrode in carbon arc welding?
Solution:
Which of the following is not a type of solid state welding?
Solution:
For resistance spot welding of 1.5 mm thick steel sheets, the current required is approximately:
Solution:
The factors that influence the stability of an electric arc include:
Solution:
Slag inclusion in a weld can occur due to
Solution:
In a welding process, the welding power parameters used are welding current = 250 A, welding voltage = 25 V, and welding traverse speed = 6 mm/s. Calculate the welding power in kilowatts (kW).
Solution:
Two pipes of inner diameter 100 mm and outer diameter 110 mm each are joined by flash-butt welding using a 30 V power supply. At the interference, 1 mm of material melts from each pipe, which has a resistance of 42.4 Ω. If the unit melt energy is 64.4 MJ/m³, then the time required for welding (in s) is:
Solution:
Based on the approach used by different manufacturing processes to obtain different shapes and sizes, they can be classified as either positive, negative, or zero processes. Which of the following is true about the joining process?
Solution:
The power source for plasma arc welding is a constant current type DC with the electrode being negative, which produces electrode wear.
