1.	Which of the following property is considered for controlling the porosity of the metal?(a) Solid solubility(b) Liquid solubility(c) Gas solubility(d) Flame solubilityI had been asked this question in class test.I want to ask this question from Metallurgy of Weld in division Welding and Related Processes of Casting-Forming-Welding II
Answer» Correct CHOICE is (c) Gas SOLUBILITY The explanation: The AMOUNT of solubility of gas in liquid or solid WELDED metals is considered to be an essential criteria for the control of porosity of the weld. The gas reactions which occur, then regulate porosity.
