Abstract

Gas Metal Arc Welding (GMAW), also known as Metal Inert Gas (MIG) Welding, has evolved over the years and a significant volume of welding is carried out by this process. The AC/DC transformer-rectifier with different control systems have been the most sought-after power sources and has served majority of the manufacturing requirements in recent times. The latest inverter based GMAW power sources with enhanced features have led to more advancements in welding technology, be it functional efficiency or welding of relatively difficult materials, joint configurations, and weld positions. This article intends to give a clarity about some of the modern power sources, their design and characteristics, and some special features that are aligned to industry needs. Part I of the article would essentially cover welding machine systems, while the subsequent parts would delve with the benefits that modern welding machines provide in to address material and manufacturing issues.
