MIG Welding Equipment | Gas Metal Arc Welding (GMAW)

MIG Welding Equipment, Gas Metal Arc Welding (GMAW). GMAW is most commonly referred to as “MIG” welding, and the following text will use “MIG” or “MIG welding” when referring to GMAW. MIG welding is a process in which a consumable, bare wire electrode is fed into a weld at a controlled rate of speed, while a blanket … Read more

MIG Welding Procedures

MIG welding procedures are similar to those for other arc welding processes. Adequate fixturing and clamping of the work are required with adequate accessibility for the welding gun. Fixturing must hold the work rigid to minimize distortion from welding. It should be designed for easy loading and unloading. A good connection of the work lead (ground) … Read more

Operating MIG Welding Equipment

Operating MIG Welding Equipment : Starting to Weld Press the inch button and allow enough wire electrode to emerge from the nozzle until 1/2 in. (13 mm) protrudes beyond the end of the nozzle. With the mainline switch “ON” and the argon gas and power sources adjusted properly, the operator may begin to weld. When … Read more

MIG Welding Machines

MIG welding machines are easy to use. Almost anyone can buy a MIG welding machine and be welding just minutes after plugging in the machine. Because of this, MIG welding machines have become very popular in recent years. MIG welding machines have come a long way since the 1980s, due to technological advancements and inventions designed … Read more

MIG Welding (GMAW)

What is MIG Welding? 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 … Read more

MIG Welding (GMAW)

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

MIG Welding Equipment

Gas metal arc or MIG welding equipment consists of a welding gun, a power supply, a shielding gas supply, and a wire-drive system that pulls the wire electrode from a spool and pushes it through a welding gun. A source of cooling water may be required for the welding gun. In passing through the gun, the wire … Read more

MIG Welding Aluminium

MIG Welding Aluminum is a fast, adaptable process that is used with direct current reverse polarity and an inert gas to weld heavier thicknesses of aluminum alloys, in any position, from 1/16 in. (1.6 mm) to several inches thick. Shielding gas for MIG Welding Aluminum. Precautions should be taken to ensure the gas shield is extremely efficient. … Read more

MIG Welding Process Principles

Arc power and polarity. The vast majority of MIG welding applications require the use of direct current reverse polarity (electrode positive). This type of electrical connection yields a stable arc, smooth metal transfer, relatively low spatter loss, and good weld bead characteristics for the entire range of welding currents used. Direct current straight polarity (electrode … Read more
