Welding Insights

Welding Procedure Specification (WPS) and Procedure Qualification Record (PQR) are essential documents in the world of welding, fabrication, and pressure equipment manufacturing. These documents ensure the welds produced meet code requirements, are repeatable, and result in safe, quality weldments. In most regulated industries such as oil & gas, power, and structural steel, the preparation and […]

Understanding Welding Consumable Nomenclature is key to choosing the right filler metal, electrode, or wire for a specific welding process, base material, and service condition. Standards such as AWS‑A5, ISO 2560, and EN 499 define naming systems used in processes like SMAW, GMAW, GTAW, FCAW, and SAW. Through careful interpretation, welders and engineers gain insight into tensile

Written by : Neeraj Dubey In oil, gas, and petrochemical industries, few terms carry more weight in fabrication and design than “sour service.” It’s not just technical jargon—it’s a critical safety and engineering consideration. If equipment isn’t properly designed or fabricated for sour service, it could suffer from serious damage like cracking, leaks, or even

The updated ASME B31.3-2024 edition brings renewed attention to a critical design parameter in high-temperature piping systems – the Weld Joint Strength Reduction Factor (W). This factor plays a pivotal role in ensuring the integrity, safety, and reliability of piping systems exposed to elevated temperatures. In this article, we’ll explore what Factor W is, when

Fractography is the study of fracture surfaces of materials, especially metals, to determine the causes and mechanisms of failure. This technique plays a pivotal role in metallurgy, materials science, and engineering failure investigations. By examining the surface of broken components using tools like Scanning Electron Microscopy (SEM) or low-magnification stereo-microscopy, engineers can uncover deep insights

Welding plays a critical role in the fabrication and assembly of metal structures, and one of the most commonly used types of welds in engineering and construction is the fillet weld. Whether used in T-joints, lap joints, or corner joints, fillet welds are known for their ease of application and strength. However, to ensure the
