All welding processes that take place without melting of the work pieces. a) - True b) - False

Answer: False

Explanation: Welding process is the joining process of two metals in which they are melted using the heat and then cooling it down and fuse them. Base metal is the melted and then some filler substance is added in the metal and then kept for the fusion process so that joining can be done. Therefore like fusion welding includes the process of melting work piece, so the statement in the question is false.
