Stainless steels are widely used in thermal power plant; pressure vessels and automobile components due to their superior fracture toughness, good inter granular corrosion resistance and non-requirement of post process annealing.Heat affected zone decreases the strength of the weld hence Pulsed TIG welding process is carried out to reduce the heat affected zone. This inherent property of the material reduces crack growth at high pressure which leads to the increase in efficiency of the pressure vessels and automobile components, when operated at high pressure.This Book describes the process…mehr

Produktbeschreibung
Stainless steels are widely used in thermal power plant; pressure vessels and automobile components due to their superior fracture toughness, good inter granular corrosion resistance and non-requirement of post process annealing.Heat affected zone decreases the strength of the weld hence Pulsed TIG welding process is carried out to reduce the heat affected zone. This inherent property of the material reduces crack growth at high pressure which leads to the increase in efficiency of the pressure vessels and automobile components, when operated at high pressure.This Book describes the process parameters like current, voltage, stand-off distance, pulse on time and weld speed, gas flow to improve weld quality. Weld speed and input current are found to be the most significant parameters. Finally, the strength of the weld is validated by tensile, hardness, bending test and Scanning Electron Microscope.
