Welding Metallurgy

Ever increasing scientific and technological developments are opening new horizons into the exploration of space and ocean depths, nuclear power, advancements in construction, communication and transportation. The availability of newer and improved materials is responsible for the significant advances in the above mentioned areas. But without proper and reliable joining techniques, many of the advanced materials would remain laboratory curiosities. There are many methods for joining but welding is acknowledged to be the most satisfactory for most metal joining operations, the most efficient and sometimes the only possible method and will probably continue to be the main method of joining structural materials. This has given an additional incentive to develop readily weldable alloys such as low carbon low alloy steels, niobium and titanium stabilised stainless steels etc.
