Basic welding positions are of 4 types which are Flat position, Horizontal position, Vertical position and overhead position. ... For fillet weld it is named as 1F (1 means the flat position and F means the fillet weld) and for Groove weld it is named as 1G ( 1 means the Flat welding and G means the groove weld).

These are good quality, 115v MIG welders. It has 100% duty cycle. ... I doubt that the machine is going to have 100% duty cycle on anything thicker than thin sheet metal, which makes the rating misleading. A duty cycle is supposed to be a rating of the machines ability at a heavy work load somewhere near its max capacity.

Horizontal Position (2F or 2G) For a fillet weld – welding is performed on the upper side of an approximately horizontal surface and against an approximately vertical surface. For a groove weld – the face of the weld lies in an approximately vertical plane.

Groove welds are stronger than fillet welds. In general, basic welding positions consist of 4 types namely flat position, horizontal position, vertical position, and overhead position. ... – 3G (Vertical Welding Position). – 4G (Welding Position Overhead or Overhead).

Base metal (T): the metal or alloy that is welded, brazed or cut. Weld metal (t): metal in fusion weld consisting of that portion of the base metal and filler metal melted during welding. You may also read more the definitions in AWS A3.

Gas metal arc welding(GMAW)( metal active gas welding - MAG) uses an active gas suc(such) as carbon dioxide and mixture of both carbon dioxide and argon called as ACM to form a shielding layer around the welding.

J-B Weld is water-resistant, petroleum/chemical-resistant (when hardened), and acid-resistant. It also resists shock, vibration, and extreme temperature fluctuations. J-B Weld can withstand a constant temperature of 500 °F (260 °C), and the maximum temperature threshold is approximately 600 °F (316 °C) for 10 minutes.

As the name suggests, the gas MIG welder needs extra shielding gas to operate while the gasless MIG welder does not. A gasless MIG welder uses a flux cored wire that is supported on a tubular wire feed. It uses vapour-forming compounds that provide a gas shield which in turn protects against oxidation.

Direct current TIG (DC) welding is when the current flows in one direction only. Compared with AC (Alternating Current) TIG welding the current once flowing will not go to zero until welding has ended.

5G welding position is used for pipe welding and the axis of the pipe is stable in horizontal position, it will not turn or rotate. 5G stands for 'groove weld'. The 6G welding test, also known as the Arkansas bellhole test, is a means to identify the skills or lack of them in a welder.

Generally, 1 gauge equipment works out to approximately 1:32 scale (roughly 10 mm = 1 foot). G scale at 1:22.5 means the 1 gauge track represents 1,000 mm (3 ft 3 3⁄8 in) metre gauge track.

Short Circuit Transfer. Short circuit, commonly called “short arc” and formally called GMAW-S, is a mode of metal transfer with low heat input where the transfer of metal from the electrode to weld puddle occurs by a series of electrical shorts.

Welding austenitic stainless steels to carbon and low alloy steels are established methods in the process and construction industries. Dissimilar metal welds involving stainless steels can be done using most full fusion weld methods, including TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas).

Spot welding is used mainly on foils or thin materials that have a thickness of a ¼ in. or less. The simplest way to remember the difference between tack and spot welds is tack welds are a preliminary step for positioning and securing pieces for welding, whereas spot welding is the final and permanent join.

Gas Tungsten Arc Welding (GTAW), also known as tungsten inert gas (TIG) welding is a process that produces an electric arc maintained between a nonconsumable tungsten electrode and the part to be welded.
