BQCIS

Engineering Integrity Through Metallurgical Expertise

The strength and safety of industrial assets depend on sound welding practices and material integrity. At BQCIS, we provide metallurgical consulting that integrates advanced analytical techniques, industry codes (ASME, AWS, API), and field experience to deliver practical, high-reliability solutions.

From procedure qualification to weld failure analysis, our services ensure that material and joining processes comply with design intent and service conditions. We assist clients in resolving fabrication challenges, optimizing welding parameters, and enhancing overall asset performance.

Whether for refinery pipelines, structural components, or pressure vessels, BQCIS ensures every weld and material meets international quality and safety benchmarks.

Success Story

Resolving Weld Cracking in a Pressure Vessel Fabrication Project

The Challenge:

A fabrication yard reported recurring weld cracking during assembly of a 40-bar pressure vessel. Initial rework led to cost overruns and schedule delays.

Our Solution:

BQCIS conducted a full metallurgical investigation, reviewed welding procedures, and optimized preheat/interpass temperatures with revised filler selection.

The Result:

The vessel achieved defect-free welds, improved productivity by 22%, and passed third-party inspection without non-conformities.
