WELDING TECHNOLOGY FOR ENERGY CONVERSION.

Energy conversions from the principal fuels such as coal, oil, gas, nuclear, and to a lesser extent the renewable sources assert demands upon material and joining to the limits of human ingenuity. This paper deals with the present development and future prospects of the newer welding processes such as electron beam, friction and diffusion bonding, in comparison with the range of arc fusion processes, together with the joint properties that are obtained. It also makes reference to particular problems such as site construction, repair, remote welding and heat treatment.
