Evaluation of Melting Efficiency in Cold Wire Gas Metal Arc Welding Using 1020 Steel as Substrate

open access: yesMetals
A key welding parameter to quantify in the welding process is the ratio of the heat required to melt the weld metal versus the total energy delivered to the weld, and this is referred to as the melting efficiency.

AISI 1030 çelik çiftinin manuel (GMAW) ve sinerjik kontrollü (GMAW-P) kaynağında tane morfolojisinin karşılaştırılması

open access: yes, 2010
In this study, AISI 1030 medium carbon steel couples of 10 mm thick were welded by the synergic controlled pulsed (GMAW-P) and manual gas metal arc (GMAW) welding techniques. For this aim, AISI 1030 medium carbon steel couples were joined through automated robotic gas metal arc welding process using an austenitic filler metal. The interface appearances
