Changes in the Geometrical Shape of a Liquid Metal Pool in Relation to a Heat Input during a Welding Process
Journal Title: Biuletyn Instytutu Spawalnictwa - Year 2017, Vol 61, Issue 3
Abstract
The article aims to present a number of factors affecting the geometrical shape of a liquid metal pool when making welded joints, i.e. factors increasing or decreasing a heat input including the density and efficiency of welding power sources, stirring efficiency, tungsten electrode tip point, heat flow in a material being welded, cooling rate and linear energy supplied to a joint.
