Causes of cracks in steel when it cools
The Causes of Fissure Formation in Cooling of Steel
When steel passes through the molten state, it cools and solidifies and forms a solid steel. As the cooling proceeds, a variety of internal stresses and strains are created due to uneven contraction, which can lead to fissures appearing along th......
heating defect
Introduction
The welding process is an essential technique in contemporary manufacturing. Welders employ various parameters and techniques to create a strong bond between two or more metal components. The resistance between the components provides the heat necessary to weld them together. However......
0Cr17Ni5Mo3N (AM350) chemical composition
AM350, also known as AISI 420 Mod., is a type of martensitic stainless steel, with UNS J91540 and AISI 420 Mod. designation. It is an advanced material intended for components and assemblies that require good hardness, corrosion resistance and wear resistance. AM350 exhibits higher corrosion resis......
Preheat and post weld heat treatment
Preheat and Postweld Heat Treatment
Preheat and post weld heat treatment are common methods used in welding processes to improve the quality and safety of welded joints. Heat treatment involves the application of heat to a specific temperature, usually followed by cooling to control the propertie......
Precipitated Phases of Weld Metal
Introduction
Welding is a common way of joining two pieces of metal, but welding is not always a good process for steel and other metals. The thermal properties and chemical properties of welded metal joints can change dramatically depending on the process and the alloy being welded. In some case......
Spot welding
Introduction
Robotic spot welding is a critical industrial process used by many automotive and large-scale manufacturing vendors to join two or more parts that are of similar thickness. The process is a form of resistance welding, ensuring two or more pieces of metal to bond together. Spot weldi......
Welding consumables for dissimilar steels
Welding of dissimilar metals has become a frequent occurence in industry over the last few decades. As welding techniques continue to evolve, so do the materials that can be welded together. One of the most common uses of welding dissimilar metals is the introduction of a high strength low alloy s......
