Welding till the End!
A stress-strain curve is a visual representation illustrating how a material behaves under increasing loads. Stress, which is the ratio of force to cross-sectional area, and strain, the ratio of a change in dimension length to the original length, are the defining factors in this graph. These curves can be constructed to examine how materials […]
The ASME B31.1 – 2022 Power Piping Code plays a pivotal role in ensuring the integrity and safety of power piping systems. One crucial aspect of this code is the meticulous examination and testing of welds to ascertain their quality and structural soundness. In this article we will discuss about visual examination as per Chapter
Welding is a crucial skill in various industries, and these books can be valuable resources for professionals looking to enhance their expertise. Here’s a list of the top 10 welding books by Indian authors along with brief explanations for each: See Best 10 books for welding by any authors Buy Welding Technology Books 1. “Welding
Welding, often referred to as the “welding arts,” is a highly specialized craft that demands a relentless pursuit of knowledge and expertise. Whether you’re an experienced welding professional seeking to elevate your skills or a budding expert aiming to refine your craft, the right books can be invaluable allies on your journey. In this article,
In the world of metallurgy and welding, certain alloy steels are revered for their exceptional high-temperature properties, among them being P91 and P92. These alloys find extensive use in power plants, industrial boilers, and other high-temperature applications. However, there’s an interesting restriction imposed on these materials: the combined content of Nickel (Ni) and Manganese (Mn)
Welding P91 material, a high-strength, heat-resistant alloy often used in high-temperature applications such as power plants, requires careful consideration of the welding process and the choice of welding electrodes. Both E9015-B91 and E9018-B91 electrodes can be used for this purpose, but E9015-B91 is preferred.
The selection of a specific welding electrode for welding stainless steel, such as SS321, depends on various factors including the application, welding process, and the desired properties of the weld joint. E347 and E321 are both stainless steel welding electrodes, but they have different chemical compositions and are designed for different purposes: Chemical composition of
Porosity is defined as “Cavity-type discontinuities formed by gas entrapment during solidification or in a
thermal spray deposit.” The porosity may be surface or subsurface, a single cavity, aligned, or clustered, and is represented by the following figures.
In the field of pressure vessels, piping, and welding fabrication, few terms carry as much gravity as “lethal service.” This designation is not just a matter of regulatory compliance; it involves the very safety of human life. Any failure in such applications can result in catastrophic consequences—loss of containment, exposure to highly toxic substances, and
Regardless of the welding process you use, there are always several factors to consider in order to achieve the best weld quality. From selecting the correct power source to choosing an appropriate filler metal and the most durable gun or torch, each item contributes significantly to the overall success of the application.But what about other
