1.	In the given figure of thermit welding apparatus, what does the question mark represents which part?(a) Sand plug(b) Crucible(c) Wax pattern(d) Slag basinThis question was posed to me in an online quiz.I want to ask this question from Thermit Welding in section Welding and Related Processes of Casting-Forming-Welding II
Answer» Right OPTION is (b) Crucible To explain: Around the parts which are to be united, SUPERHEATED LIQUID steel is POURED, which then effects in FORMING the weld. This process, hence, is a fusion welding process. The part represented by the question mark is the crucible.
