Question 16

What is welding?

Answer 16

• Welding fuses together metals at a very high temperature
  1) High heat melts the bases material
  2) Metal filler (welding rod) is melted to fill the joint
  3) Once the parts cool down, they are fused together which creates a very strong joint

P.S - Spot welding is a quick version of welding
