In gas welding, the joint can be made even much stronger than the original.(a) True(b) FalseThis question was posed to me during a job interview.The origin of the question is Gas Welding in portion Welding and Related Processes of Casting-Forming-Welding II

Answer»

Correct option is (a) True

For explanation I would SAY: In gas welding, various metals like cast IRON, steel, aluminium, copper etc. can be used for joining operation. First they brought into a molten state and then a fusion is taking place between two pieces of metal in such a way that the point of fusion CLOSELY approaches the strength of the metal fused. In this process, the union or joint can be MADE even much STRONGER than the original.
