Time consumed during thread checking
Time consumed during leg welding

v Solutions:
4.5.1 No Nugget formed:
To check that spot welding done is correct or not we test the piece in Electronic Universal Testing Machine and measure the nugget formed. Firstly we do spot welding of two pierced pieces and fixed it between two clamps as shown in fig. then the machine works and breaks the spot. Problem faced that there was no nugget formed.
