Ga Metal Arc Welding Gun Diagram

Terminology of gas metal arc welding.

Ga metal arc welding gun diagram. As described in the next section self. Mig metal inert gas or gas metal arc welding gmaw is a welding process in which a consumable metal electrode is used to produce the electric arc to join the metal pieces together in the environment of a shielding gas. Gas metal arc welding gmaw by definition is an arc welding process which produces the coalescence of metals by heating them with an arc between a con tinuously fed filler metal electrode and the work. Stick welding is one of the most widely used welding processes.

Conditions that affect weld. The eastwood weld prep tool is an exclusive design that provides a perfectly beveled 450 weld prepped edge in 20 or 18 gauge sheet metal to achieve solid full penetration mig or tig butt welds. Typical gmaw semiautomatic setup with voltage sensing feeder 7. Constant voltage direct current power source is used to produce the arc.

An electric current in the form of either alternating current or direct current from a welding power supply is used to form an electric arc. Typical gmaw process control settings 8. It is a manual welding process that employs electric arc that formed when the electrode maintains a contact with base metal as its source of heat to melt the consumable electrode and its protective flux shielding along with the base metal. The typical gmaw welding gun has a number of key partsa control switch a contact tip a power cable a gas nozzle an electrode conduit and liner and a gas hose.

Typical gmaw semiautomatic setup with constant speed feeder 6. Gas metal arc welding gmaw sometimes referred to by its subtypes metal inert gas mig welding or metal active gas mag welding is a welding process in which an electric arc forms between a consumable mig wire electrode and the workpiece metals which heats the workpiece metals causing them to melt and join. Simple diagram of the gas metal arc welding process. Terms in this set 8 gmaw gun.

Gmaw gun assembly part id. The application of gmaw generally requires dc reverse polarity to the electrode. Besides the welding gun the actual equipment required for the gmaw process includes an electric power supply the electrode wire feed unit and a source of shielding gas. Along with the wire electrode a shielding gas feeds through the welding gun.

Shielded metal arc welding smaw also known as manual metal arc welding mma or mmaw flux shielded arc welding or informally as stick welding is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld. Gas metal arc welding gmaw is a high speed economical process that is sometimes referred to as metal inert gas mig welding figure 1in this process an arc is struck between the base metal and a continuously supplied consumable electrode which provides filler metal for the weld 2the electrode is bare containing no coating or core. The gas nozzle directs the shielding gas evenly into. The process uses shielding from an externally supplied gas to protect the molten weld pool.

The gun guides the electrode wire current wire and shielding gas tube. Holding and positioning welding gun 9.
