In the spot welding:
  • a)
    It is desirable to clean the sheets thoroughly before welding
  • b)
    The workpieces being welded are pressed together by mechanical pressure exerted through electrodes
  • c)
    The current required is above 5,000 A and the voltage between the electrodes is usually less than 2 V (open-circuit voltage less than 12 V)
  • d)
    All of the above
Correct answer is option 'D'. Can you explain this answer?

Spot welding means the joining of two metal sheets and fusing them together between copper electrode tips at suitably spaced intervals by means of heavy electric current passed through the electrodes.
It is desirable to clean the sheets thoroughly before welding.
The welding current varies widely depending upon the thickness of and composition of plates. It varies from 1000 to 10000 A and voltage between the electrodes is usually less than 2 V.
