Weld Stress and Distortion
Welding Stress and Deformation
Welding is a common type of joining used for both structural and non-structural elements. Welded components are found in products ranging from automobiles and ships to bridges and skyscrapers. Despite the wide variety of applications, welding is associated with a nu......
Weldability test lap joint (CTS) welding crack test method GB 4675.2-84
In the CTS welding crack test, the most important is to prepare the test specimen. Before the weldment is tested, it needs to meet certain requirements, otherwise the results obtained will not be meaningful. For example, the welding itself should be performed skillfully, and the components of the w......
Weldability Test Method for Maximum Hardness of Welding Heat-Affected Zone GB 4675.5-84
Abstract
Weldability testing is an essential part of welding process in the manufacture of structural components to ensure the reliability and durability of the weldments. The highest hardness test method (GB 4675.5-84) is one of the welding performance tests, by which the maximum hardness of the......
1Cr12Mo use
1Cr12Mo Introduction
1Cr12Mo is a Fe-Cr-Mo alloy designed for welding and post-weld heat treatment. The high carbon content and low sulfur content of 1Cr12Mo increase its hardness and wear resistance, making it suitable for corrosive and abrasive environments. The addition of high molybdenum cont......
12Ni14 use
12Ni14
Introduction
12Ni14 is a quality carbon steel that belongs to the 12NiCrMoV stainless steel family. This material is widely used because of its strength and durability, particularly in areas where high temperatures and corrosion, or abrasion are found. 12Ni14 is widely used in power plant......
40CrMoV4-6 uses
40CrMoV4-6 is a grade of high-temperature and creep resistant steel that is used in applications such as power generation, transportation, construction, and chemical processing. The high strength and enhanced creep resistance of 40CrMoV4-6 make it an ideal choice for components that are exposed to......
