Guide to Quality Testing in Steel Fabrication

Introduction to Steel Fabrication

To explain it in simple words, the process of modifying the raw steel into the desired shape required for the construction of architectural projects like buildings, bridges, machinery, vehicles, etc. is called “Steel Fabrication”.

This process involves 5 essential steps:

• Cutting;
• Bending;
• Welding;
• Drilling;
• Finishing.

However, to ensure the efficient fabrication, companies like Horizon Steel – steel supplier in UAE do it with high precision and accuracy to get the final products per client’s expectations.

 Quality Testing

The process through which it is verified that the performed steel fabrication of the desired steel is according to the specifications, and to ensure the product’s reliability and safety is called Quality testing.

Steps of Inspections

Metallurgical Inspection

To analyze the chemical composition, microstructure, and physical properties and determine the grade, quality, and suitability of steel products the Metallurgical Inspection is used.

Mechanical Inspection

It measures the strength, hardness, ductility, toughness, fatigue resistance, and wear resistance, to evaluate how the steel products are going to perform when put under diverse stress and conditions.

Non-destructive Inspection

To find out any sort of structure or performance-related flaws in steel products without causing any modification in the product is named Non-Destructive Inspection. There are numerous methods steel products can be inspected non-destructively:

• Visual inspection.
• Magnetic particle testing.
• Liquid penetrant testing.
• Ultrasonic testing.
• Radiographic testing.
• Eddy current testing.

Dimensional Inspection

As it is apparent from its name, this type of inspection involves the verification of the dimensions, shapes, tolerances, and alignments of steel products with the help of mechanical and technical tools like old-school calipers, gauges, rulers, lasers, scanners, etc.

After the types of inspection come the turn of various criteria and guidelines that determine the standard methods for quality testing.

ASTM

A global organization, ASTM, has to-date covered thousands of aspects via which quality testing in steel fabrication is performed hence, ensures the development and issue regarding voluntary consensus standards for materials, products, systems, and services.

AISC

It is a United States-based professional association that not only presents structural steel fabrication industry but also provides certification ensure the adherence to the official standards.

AWS

AWS is a professional society that publishes codes and specifications related to advanced science and technical welding quality control and inspection.

CSA

This Canadian organization develops and maintains standards for welding quality assurance and certification, same as AISC.

Conclusion

Quality testing in steel fabrication verifies the quality and performance of steel products according to the specifications and requirements, and this procedure involves adhering to numerous standards and guidelines.
