1.	On which of the following factor, does weldability not depend?(a) Boiling point(b) Melting point(c) Thermal expansion(d) Thermal conductivityI had been asked this question in an online quiz.This intriguing question originated from Weldability in section Welding and Related Processes of Casting-Forming-Welding II
Answer» Right answer is (a) Boiling point For explanation I WOULD say: Weldability is dependent on five factors of the metal or alloying element. The factors being, melting point, thermal EXPANSION, thermal conductivity, surface CONDITION and CHANGE in the MICROSTRUCTURE.
