These articles contain information about the basics of MIG welding or GMAW welding, with a special focus on some popularly used MIG welders in the industry.
Gas metal arc welding is a versatile process that is used widely to weld aluminum. Direct current electrode positive polarity is used, and an inert gas is used to provide shielding. The process can be adapted for out of position welding as well. Shielding Gas Aluminum is a reactive metal. Hence an efficient shielding is … Read more
Mas Metal Arc Welding (GMAW), or MIG welding, offers several advantages over other conventional processes such as shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), etc. Some of these advantages are as follows: The main advantage of metal inert gas welding or MIG welding is the high rate of weld metal deposition as compared to SMAW … Read more
Electrodes used for gas metal arc welding process (or MIG Welding) are smaller than those used for other welding processes. This is because of the high current and speed at which the welding filler material is introduced into the weld puddle. The MIG welding wire comes in various sizes, and are available for most of … Read more
This article discusses the various components used in the MIG welding equipment. GMAW Equipment The equipment used for gas metal arc welding consists of a power source, a welding gun, a shielding gas supply, a wire-feed mechanism that draws filler wire from the spool and feeds it to the welding-gun, cables to conduct current, and … Read more
MIG welding, also called Gas Metal Arc Welding (GMAW) is an arc welding process in which joining of metals is obtained by heating the metal with an arc struck between the work-piece, and an electrode that is continuously fed through the welding torch. The shielding is provided through an externally supplied gas, often argon, which … Read more
MIG welding, Gas metal arc welding (GMAW ) is an electric arc welding process that joins metals by heating them with an arc established between a continuous filler metal (consumable) electrode and the work. Shielding of the arc and molten weld pool is obtained entirely from an externally supplied gas or gas mixture, as shown … Read more
