What is MIG Welding? Metal Inert Gas (MIG) welding‚ also sometimes called Gas Metal Arc Welding (GMAW) is a process that was developed in the 1940s for welding aluminum and other non-ferrous metals. MIG welding is an automatic or semi-automatic process in which a wire connected to a source of direct current acts as an electrode to join two pieces of metal as it is continuously passed through a welding gun. A flow of an inert gas‚ originally argon‚ is also passed through the welding gun at the same

Arc Welding or SMAW Generally known as stick or arc welding. Arc welding is the most basic of all welding types‚ is easy to master in a home welding situation. Stick welding can be used for manufacturing‚ construction and repairs‚ very much well suited for heavy metal size 4 millimetres upwards. Thinner sheet metals and alloys are usually more suited to the mig welding types. STEPS: 1. Gather your materials. You should have a welding machine‚ electrode holder with lead‚ ground clamp with lead‚

Basically welding is just the cutting and joining of metal by applying heat to pieces of metal and fusing them together to form a permanent bond. Welding is used in a lot of processes such as; shipbuilding‚ automobile manufacturing and repairing‚ aerospace applications and many others. In addition to that welding is also used in construction to join steel beams of buildings and bridges and pipes in pipelines. Welders work in a wide variety of industries‚ from car racing to manufacturing. The work

[2] reported that the use of pulsed arc welding in place of conventional GTAW increases the output by 200–400%‚ reduces consumption of argon by three to ten times‚ and also reduces the cost of 1 m weld deposition by three to five times. The aim of pulsing is mainly to achieve maximum penetration

resistance spot welding process parameters on the shear-tensile strength of the welded joints of Inconel alloy 625 was investigated. Experimental study using full factorial design of the welding current‚ welding time‚ and electrode force parameters was conducted. In order to identify the influence of each parameter and their interaction a general linear model and a second order model using response surface method was developed. Nonlinear correlation was observed between the welding process parameters

NO THANKSGET THE APP how heat affects metal when it is being welded (peasecha) Charles Pease 3-29-16 English 10 How heat produced from welding affects metal The heat produced from the welding process can cause deformation and can also cause changes in the metal at a molecular level. This can make the metal brittle and even deform it. When the arc is struck and the metal starts to become molten it reaches temperatures in an excess of 8‚000 degrees fahrenheit and such a large input of heat
