The PWHT procedure is a controlled thermal approach used after welding to reduce residual stresses and improve metal strength. It helps prevent cracking, distortion, and early failure in industrial components, and follows precise steps of heating, soaking, and controlled cooling under strict conditions. In this blog, we explain the complete PWHT procedure step-by-step and why […]
Heat treatment of metals is one of the most important processes used to improve strength, durability, and performance in industrial materials. If you are working with metal parts that fail, crack, or wear out too quickly, the problem is often not the material but how it is treated. This guide explains everything in simple terms […]
Understanding how induction heating works starts with one insight: the heat isn't applied to the metal—it's generated inside it. This single distinction makes induction one of the most precise, efficient, and versatile thermal processes in modern industry. Whether you're a plant manager looking to increase efficiency or simply curious about industrial heating processes, this guide […]
Hydrogen bake out procedure is a critical process used to remove hydrogen from steel and prevent cracking after welding or exposure. When hydrogen enters metal, it can weaken the structure and cause sudden failure. This is why industries like oil and gas rely on this process. In this guide, you will learn the hydrogen bake […]
Field heat treatment is what separates a weld that lasts from one that fails quietly a few weeks later. On-site welding traps stress inside the metal, creating hidden risks of cracks, warping, or sudden failure. Applying controlled heating and cooling right where the equipment sits not only stabilizes the metal but also protects pipelines, pressure […]

Induction heating vs resistance heating is one of those decisions that can make or break your line. One blasts heat fast and precise, the other spreads it slow and steady. Pick wrong, and you waste energy, slow down work, and stress your equipment. In this guide, we cut through the jargon, break down how each […]
Proper Planning When planning PWHT of any pressure vessel the unequivocal number one concern should be vessel integrity during the heat cycle as this is where any damage is going to happen. The cost of having a bad PWHT and causing damage to the material, internals, externals, or the vessel integrity itself could have irreversible […]
Heat Treatment Applications These are the common applications for Heat Treatment Post Weld Heat Treatment (PWHT) Post Weld Heat Treatment (PWHT), also referred to as stress relieving, is an application of controlled heat applied after the welding is complete. PWHT is the relaxation of residual stress caused during the welding or in other processes such […]
Background Axiom Heat Treatment sought to develop new technology in an industry that has seen very little change over the years. Axiom developed a new and innovative technology to reduce power consumption and treating time cycles for field heat treating services. Axiom began a process of developing and testing a new methodology which included design, […]
