Introduction MIG (Metal Inert Gas Welding) or Inert Gas Welding. In the process the electrodes are melted and mixed with molten parent metal to form a weld pool. Thus‚ the electrode must be supplied constant current throughout the welding process is carried out. For a continuous supply of electrodes‚ the electrodes are made in the form of wire to be extended out from the nozzle welder automatically at a specified speed. Protective gas is supplied through the nozzle weld as is done in TIG welding. This process

produce welded components safely using a selected welding process” What is MIG welding? MIG welding which stands for Metal Inert Gas‚ also known as Gas Metal Arc Welding (GMAW) is a welding process in which an electric arc forms between the wire electrode and the metal work piece. This then heats the metal work piece as well‚ causing them to melt and join together. Along with the wire electrode a protective gas called shielding gas is fed through the welding gun which shields the whole process of the weld

Welding is the only process which is carried out to merge two metals and it is an absolute need that a person who welds should wear a helmet to protect himself from the fire sparks. The headgear protects the welder’s eyes‚ face and neck from flash burn‚ ultraviolet light‚ sparks‚ heat and infrared light. It will prevent from retina burns which lead to loss of vision. In order to avoid this unprotected exposure to the ultraviolet and infrared rays it is necessary to make use of the right helmet which

MIG (Metal Inert Gas) welding is a type of welding that forms an electric arc between the metal and a wire electrode. The electric arc between the metal and the electrode melts the metal and allows it to be joined. An inert gas shield travels through the welding gun‚ which serves as protectant from outside air contaminating the process. This process generally requires a direct current power supply‚ but sometimes alternating current power systems are used. Electrodes are wires that allow an electric

Welding is the joining of metals. Modern welding is that there are four components. The four components are the metals themselves‚ a heat source‚ filler material and some kind of shield from the air. When considering a career in welding‚ a person must carefully look into the responsibilities this will entail‚ the skills one must have to succeed‚ plus another important aspects such as working conditions‚ salary‚ and the future of the job; however‚ just as important is to carefully seek out the Texas

occupation What is welding‚ and how does it work? Not many people know what welding is or how it works. According to Mary Bonk“welding is the process of heating and melting metal parts to join them together” (Bonk‚3). A welding machine uses electricity to melt the electrode‚ fusing one piece of metal to another. The welding machine uses a ground that connects to the surface that allows the welder to create a flowing currant passing through the electrode and the metal that the welder is

covers processes such as welding‚ brazing‚ soldering‚ adhesive bonding‚ and mechanical joining. These processes are an important and necessary aspect of manufacturing operations. This paper deals with one topic in particular ‘Welding’. Welding is a process for joining similar metals. Welding joins metals by melting and fusing the base metals being joined and the filler metal applied. Welding employs pinpointed‚ localized heat input. Most welding involves ferrous-based metals such as steel and stainless
