This category of articles contains some of the commonly welded metals in the industry, their properties, methods of testings to determine their properties, and welding consumables used to weld these base metals with various welding processes.
High carbon steels are those with a carbon content exceeding 0.55 percent. These are very difficult to weld because they are prone to cracking which is the most usual problem in carbon steels. Special measures are required to be incorporated in the welding procedure in order to avoid a hard microstructure that is brittle, and does … Read more
Aluminum is a very sought after material due to its many desirable properties. Some of these properties are: lightweight, excellent strength to weight ratio, easy machinability, formability, and weldability. Although pure aluminium has limited usability, it has vast usage when it is alloyed with few alloys. Fabrication using aluminium involves welding. And welding aluminum requires … Read more
Non-consumable tungsten electrodes for GTAW (Gas Tungsten Arc Welding) or TIG (Tungsten Inert Gas) welding, generally are of several types. Types Of Tungsten Electrodes Tungsten electrodes types and their typical application can be identified by color-coded end marks as follows. Pure Tungsten Electrodes Pure tungsten electrodes are generally used on less critical welding operations than the tungsten electrodes … Read more
