ANALYSIS OF CONDITIONS FOR OBTAINING A KEYHOLE REGIME FOR LASER WELDING
Journal Title: TEHNOMUS - Year 2011, Vol 18, Issue 1
Abstract
For laser welding using high intensity of laser beam produce the keyhole phenomenon in welding pool. For keyhole welding regime there is a particular of the weld cross-section shape aspect given by the heat affected zone area. It analyzes the laser welds made with Nd: YAG laser on low alloy steel plates using irradiation in continuously regime. The power, welding speed and defocusing are varied. Experiments were conducted after the full factorial experimental design 22. This showed the effect of laser power for setting keyhole welding regime.
