Answer 2

Answer:

In spot welding, for lap joint, the diameter of welded joint ( weld nugget ) should be 2t+2.5 mm.

Explanation:

Weld nugget Diameter:

• Weld nugget diameter is defined as by peeling one of the sheets back over the spot weld the major and minor button diameter was determined by leaving a hole in one sheet and a button of material attached to the other sheet gives the average diameter.

Nugget Welding:

• Nugget welding is defined as by the application of electric current and pressure the welding of overlapping pieces can be done.
• Spot weld nuggets are measured by pulling the test coupon or part apart after welding.
• The diameter of nugget should be at least 5mm when spot welding of two pieces is 1 mm.
• The minimum nugget size should be 5 times greater than the original metal piece.
• In spot welding, for lap joint, the diameter of welded joint ( weld nugget ) should be 2t+2.5 mm.

t = thickness of metal sheet
