MCE 329 NOTE METALLURGY OF WELDING Metallurgical Phenomena Welding is a complex process that involves: - Gas-metal & slag-metal reactions - Solidification - Metallurgical reactions in the solid state • annealing & recovery • grain growth • precipitation • phase transformation These metallurgical phenomena control weld strength and ductility Gas-Metal Reactions • Reactive gases (especially N , 0 , H ) may be present in ...
Welding Metallurgy elding usually involves the melting of a filler metal and its deposition in a groove between two pieces of solid metal in order to join them. This and similar processes involve some important physical and chemical processes such as the rapid heating, W melting and superheating of the filler metal and possible reactions that may take place between the molten or re-solidified metal ...
