ASTM E23 Charpy Testing
ASTM E23 is a standard developed by the American Society for Testing and Materials (ASTM) International. It outlines the procedures for performing standardized tests on materials and components to determine their mechanical properties. The standard explicitly covers...
Basic Understanding of Corrosion and Pipeline Inspection
Basic Diagram of Corrosion Process on Steel Corrosion of steel is a process by which the metal deteriorates and deteriorates over time due to exposure to various environmental factors such as moisture, chemicals, and oxygen. It is a common problem for many steel...
History Of Welding Aluminum
The GTAW process is quite often a viable option for welding aluminum. It was developed in 1944 and is still used to weld aluminum alloys today. Some of the highest quality welds used in critical applications, such as full penetration pipe welds on cryogenic pressure...
Effects of Heat Input on Mechanical Properties of a Weld
Welding variables have minimal effect on the final welded joint for many applications. Many applications involve thin plain carbon steel such as A36 or similar grades. Variables become critical when welding higher-strength or alloyed base materials. To produce...
Causes Of Defects In Concrete Structures
Concrete is known to be a very versatile and reliable material. Construction errors and negligence can lead to defects in a concrete structure. These defects in concrete structures can be due to: Poor construction practicesPoor quality controlPoor structural design...
Post Weld Heat Treatment
Things Welding Inspectors Should Know When welding base materials, preheating and/or post-weld heat treatment may be necessary. These thermal treatments are generally required to ensure suitable weld integrity. They will typically prevent or remove undesirable...
An Introduction to Mechanical Testing for Welding Procedure Specifications
General: The purpose of WPS/PQR Qualification is to ensure that the fabricator's welding procedures are qualified before the job application, per the Customer's requirements. This post covers the welding jobs performed in the production of platforms (including the...
Upfront Welding Inspection Considerations
Welding inspection involves much more than checking the accuracy of welds. Inspectors must know codes, standards, materials, and other fabrication processes. Welding inspection is not something to take lightly. Lives can depend on the accuracy of the inspection....
A Welding Inspector’s Tools of the Trade
Weld inspectors, especially those new to the trade, put a lot of emphasis on the equipment needed to do the job. Flashlight Mirror High-low gauge Pit gauge Bridge camera Borescope However, this isn’t the entire toolkit. A welding inspector must also know the...
