Electromagnetic Force in Laser Welding by romanosky11 is a document available to read on EtoBox.
This document summarizes a study on using electromagnetic force to prevent porosity formation in pulsed laser keyhole welding. The study found that porosity forms when the solidification rate of molten metal exceeds the backfilling speed during keyhole collapse. Electromagnetic force was proposed to control the backfilling speed and a mathematical model was developed to investigate its effects. The results demonstrated that electromagnetic force can prevent porosity by achieving quality welds when applied a
