Metal Welding - Types and Processes Welding. So you think it’s as simple as grabbing the gun and pulling the trigger‚ eh? Tell me this then - what types of welding are there? Not completely sure? Read on... Arc Welding Arc welding is a process utilizing the concentrated heat of an electric arc to join metal by fusion of the parent metal and the addition of metal to joint usually provided by a consumable electrode. Either direct or alternating current may be used for the arc‚ depending upon

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‚

“American Welding Society” and you absolutely need this certification before any company will even let you pick up a stinger. This certification is easy to obtain if you are an experienced welder and needs to be renewed every six months or every time you switch companies. Secondary certifications consist of going to college to master the positions‚ machine temperatures‚ and overall welding experience. No matter what‚ even if you have

Underwater welding‚ Underwater welding was invented in Russia in 1932 by Konstantin Konstanovich Khrenov and used it throughout the soviet navy. During WWII‚ the American Cyril D. Jensen‚ professor of engineering at Lehigh university‚ developed the USA’s own underwater welding programs and created 2 U.S. patents in the field. (Agnew‚ 1999-2013) Under water is a technique that is employed in various engineering projects‚ where in welding is carried out under the surface of the water. Underwater

Aluminium Alloy 7039 Anoop C A‚ Pawan Kumar Department of Mechanical Engineering‚ NIT Calicut (Kerala)‚ India VRDE‚ Defence Research and Development Organization‚ Ahmednagar (MS)‚ India Vainarman et al. [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
