1.what is welding?
Welding is the most common way of permanently joining metal parts. In this process, heat is applied to metal pieces, melting and
fusing them to form a permanent bond. Because of its strength, welding is used in shipbuilding, automobile manufacturing and
repair, aerospace applications, and thousands of other manufacturing activities. Welding also is used to join beams when constructing
buildings, bridges, and other structures, and to join pipes in pipelines, power plants, and refineries...>>more
2. What is GMAW?
Gas metal arc welding (GMAW) is an automatic or semi-automatic welding process. Also called MIG (Metal Inert Gas) welding
.Shielding gas and a continuous, consumable wire electrode are fed through a welding gun. GMAW uses a constant power source
such as voltage or a direct current to weld together materials such as steel and aluminum. GMAW is popular in industries such as car
manufacturing due to its speed and versatility...>>more
3. What is TIG?
Tungsten inert gas (TIG) welding is the process of blending together reactive metals such as magnesium and aluminum. The TIG
welding method became popular and useful in the early 1940s and, as a result, has greatly propelled the use of aluminum for welding
and structural processes. TIG welding is commonly used for both high quality and manual welding.
During the process of TIG welding, an arc is formed between a pointed tungsten electrode and the area to be welded. As a result
of the gas shield, a clean weld is formed. This prevents oxidization from occurring...>>more
