A Welding Procedure Specification, or WPS, is essential to creating consistent, high-quality products with a confidence that they will withstand the expected service conditions. A WPS purpose is to detail proven welding parameters procedures to guide welders as...
Surface contaminants, defects, and contamination arising through fabrication are all potentially detrimental to the oxide film that protects stainless steel. Corrosion can be initiated from the moment stainless steel has been damaged. Therefore, it is imperative that...
What is a welding supervisor? A certified welding supervisor is responsible for ensuring compliance of all welding activities. Some of these activities include: applicable safety requirements drawings plans weld procedures standards relevant documents. A...
Preheating involves the application of heat on a fabrication or component before commencing the welding process. In this blog, we will discuss the basics around welding preheat. Why do we need to preheat? Preheating is used for a number of reasons, including: Avoiding...
The Most Common Welding Defects: Causes and Remedies A weld flaw is any indication on a weld that can compromise the quality of the weld. A weld flaw can be accepted or rejected depending on three factors: type, size and location of the flaw/discontinuity. All welds...
There are five basic NDT (non-destructive testing) methods used to detect weld defects; Visual Inspection (VT) Magnetic Particle Testing (MPT) Dye Penetrant Liquid Testing (DPI) Radiographic Testing (RT) Ultrasonic Testing (UT). UT and RT can detect both external and...
