Welding Condition of Thin Plates in Pulsed TIG Process

Abstract

A mathematical solution, derived from heat flow, was proposed for determining pulsed TIG welding conditions for various thin plates. The justification of it was confirmed through experiments of welding with mild steel, stainless steel (18Cr-8Ni), Invar (35-36%Ni) and pure copper.
Welding conditions of various thin plates can be determined by some calculations and a few experiments if the thermal properties are given.
