Algorithm for CO₂ Arc Welding Parameters of Flat Position Fillet Joint

Abstract

An algorithm and program for determination of CO₂ arc welding parameters of flat position fillet joint has been studied under given fillet sizes and welding speeds. Two torch angles examined were at 45° and 25°. The proposed program is applicable to the globular transfer condition using wier of 1.6 mm in diameter. Calculated parameters were confirmed experimentally to give good bead appearance for fillet sizes from 5.5 to 12 mm. Effect of welding parameters on the relation between effective throat thickness Te and theoretical throat thickness T was also calculated.
