A Newtonian fluid is one where there is a linear relationship between stress and strain-rate. The ratio of stress to strain-rate is the Viscosity of the fluid. A fluid where there is no linear relationship between stress and strain-rate is called a Non-Newtonian fluid.
7) The stress strain relationship of a Newtonian fluid is

Answer is:
Electron Beam
Explanation:
Electron Beam welding techniques require a vacuum environment.
Electron Beam Welding is a welding process utilizing a heat generated by a beam of high energy electrons. The electrons strike the work piece and their kinetic energy converts into thermal energy heating the metal so that the edges of work piece are fused and joined together forming a weld after Solidification. Electron Beam Welding is performed under vacuum conditions to prevent dissipation of the electron beam.
