Low carbon steel is the most common type of steel found in the industry. Welding low carbon steel does not pose any great difficulties to an experienced welder. It is considered an easy task, low carbon steel is the most weldable of all. However, there are a few basics that must always be borne in … Read more
This article discusses about welding of medium carbon steel. It offers a few pieces of advice for obtaining a quality weld. Introduction The carbon content in medium carbon steel ranges from 0.30 to 0.55 percent. After welding, these steels are heat treated to relieve the residual stresses. Medium carbon steel is fabricated in the bar … Read more
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
