Abstract
The present study examines the mathematical analysis of a one-dimensional heat-transfer model for the pulsed Nd YAG laser-welding process. A quasi-steady solution for the temperature rise in the weld region is attempted, the solution being obtained for the surface temperature to reach 90% of its steady-state value. In addition, the laser spot-welding of sheet metals has been carried out with oxygen and argon assisting gases at atmospheric pressures. It is concluded that the use of oxygen reduces the tensile strength whilst the use of argon increases the tensile strength of the resulting welds, when compared with air ambients.
