Prediction of the penetration depth in laser beam welding
KSME Journal, 1990Three dimensional solution for the heat flow in laser beam welding with a constant moving Gaussian heat source has been analyzed. The temperature rise and cooling rate are related to the beam spot size, travel speed and laser power. As an application of this model, the theoretical predictions were compared to the experimental data in which laser ...

Journal of Laser Applications, 1990
Experimental data have been generated for the bead-on-plate keyhole welding of mild steel using the TEM00 beam from a 1.5 kW CO2 laser and a range of material thickness from 0.64 to 2.6 mm. For each thickness, the maximum welding speed was measured for laser powers from 600 to 1500 W, using the criterion of full penetration along a 5 cm length ...

Welding Parameter Response to Depth Penetration—An Experimental Study
2021To join ferrous and non-ferrous metals, metal inert gas welding (MIG) is an essential welding operation. The welding quality is affected by the MIG input welding parameters, and the weld bend geometry affects the weld quality. This paper describes the factors that affect the welding parameters (voltage, current, speed, and AISI 1020 steel penetration ...

On-line monitoring of penetration depth in laser beam welding
ICALEO '97: Proceedings of the Laser Materials Processing Conference, 1997The penetration depth is one of the fundamental process parameters in laser beam welding. On-line monitoring and control of the penetration depth is a significant contribution to meet todays quality requirements and enhance the integration of laser technology into manufacturing.

Comparison of Residual Stress Depth Profiles in Welded Joints
Materials Science Forum, 2002A general problem for the evaluation of measurement results of residual stresses due to welding is the limited knowledge about the residual stresses e.g. only the residual stresses at the surface can be determined. Residual stress measurements in TIG-welded joints of a steel S960Q1 have been carried out by means of X-rays, by neutron scattering and by ...
