hot cracking welding

What Is Hot Cracking (Solidification Cracking)?

Hot cracking is a metallurgical phenomenon that often occurs during welding and casting processes, leading to structural defects and compromised material integrity. Understanding hot cracking and its causes is crucial for engineers, welders, and anyone involved in the fabrication of metal components. In this blog, we will delve into the world of hot cracking weld

Sensitization in stainless steel?

Sensitization is a phenomenon that can occur in stainless steel. It is a critical concept that needs to be understood as it can adversely affect the performance of stainless steel. This causes the steel or alloy to become susceptible to intergranular corrosion or intergranular stress corrosion cracking (SCC). What are stainless steels? Stainless steels are

What are austenite and ferrite stabilizing elements?

Austenite and ferrite stabilizing elements are terms used in the context of alloying elements in steel and other materials to describe their influence on the microstructure and phase composition of the material. These elements promote the formation of either the austenite phase or the ferrite phase, which are two different crystal structures in metallic materials.

What is TIG Welding (GTAW) & How it Works

Gas Tungsten Arc Welding (GTAW), also known as TIG welding, is a captivating combination of science and craftsmanship. It is considered one of the most precise and versatile methods in the welding industry, capable of producing flawless and superior welds in different materials. In this blog, we will explore the fundamental principles, necessary equipment, essential

What Is Stress Strain Curve?

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

Acceptance criteria for visual examination as per B31.1

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
