Welding is prone to the top ten welding errors (1)

Welding is a complex subject, and this article is far from being comprehensive on any aspect of it. However, one thing that it attempts to cover is a few absolutely necessary requirements and a number of basic beginner mistakes that one can easily avoid--Sale Of Welding Positioner.

As a quick introduction, the most frequently used and easiest-accessible welding processes are arc welding/gas welding (including tig welding and mig welding)--Sale Of Welding Positioner.

Arc welding describes welding processes that use a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point. They can use either direct (DC) or alternating (AC) current, and consumable or non-consumable electrodes. The welding region is sometimes protected by a kind of inert or semi-inert gas, known as a shielding gas, and/or filler material. Arc welding is widely used because of its low capital and running costs.

MIG (Metal Inert Gas) and TIG (gas tungsten arc) welding are kinds of gas metal arc welding. During MIG and TIG welding, continuous and consumable wire electrodes and a shielding gas are fed through a welding gun. Constant voltage, direct current power source are usually used with MIG and TIG welding, but alternating current sources can also be used. Originally used for welding aluminiums, gas metal arc welding was also soon applied to steels because it allowed to reduce welding time substantially--Sale Of Welding Positioner.

Some advantages of MIG welding are that it is easier to learn, longer welds can be made without the need to stop and restart, and little post weld cleaning is necessary. The downsides are an oxidized weld deposit, unstable arc, and weld porosity. Advantages of TIG welding are that it allows welds of higher quality, with or without filling metal, good control of heat, and low distortion. Some of the issues with TIG welding are a somewhat erratic (wandering) arc, a high electrode consumption, and a certain porosity of the weld.
