Experimental and Theoretical Studies on Transport Processes in Laser Welding

摘要

Progress has been made in areas related to fluid flow, heat transfer and alloying element loss during laser welding of stainless steels. The progress is reported under the following headings: weld pool temperature, alloying element vaporization rate, and solute loss; absorption of CO sub 2 laser by stainless steels; numerical calculation of fluid flow in laser melted pools; and microstructure of the welded material.
