The OSHAA 30-Hours Professional Diploma in Quality Assurance / Quality Control (QA/QC) and Piping Engineering is a specialized training program designed for professionals seeking to excel in quality inspection, welding, and piping systems within industrial and construction environments. This diploma equips learners with both theoretical knowledge and practical skills that are vital in industries such as oil and gas, petrochemicals, power generation, and large-scale infrastructure projects.
Throughout the course, participants are introduced to the fundamentals of QA/QC, including piping materials, fabrication practices, welding technologies, and international standards such as ASME, API, and ISO. A strong focus is placed on non-destructive testing (NDT) methods, visual inspection of welds, and interpretation of piping isometrics and engineering drawings, ensuring participants can identify defects and ensure compliance with quality requirements. Learners also develop competencies in preparing and reviewing inspection and test plans (ITPs), quality documentation such as WPS, PQR, and NDT reports, as well as applying practical field-based inspection techniques.
Beyond technical expertise, the diploma emphasizes the importance of global codes, site quality procedures, and regulatory compliance, preparing professionals to meet industry standards at an international level. By mastering inspection workflows, defect recognition, and documentation processes, graduates are positioned to play a key role in maintaining the structural integrity and safety of piping systems and welded joints.
The course benefits include gaining industry-recognized QA/QC knowledge, strengthening inspection and documentation skills, and improving career prospects in the highly competitive sectors of construction, oil and gas, and power plants. Graduates are prepared for roles such as QA/QC Piping Inspector, Welding Inspector, NDT Technician, or Site Quality Engineer, contributing to both project success and workplace safety.
Looking forward, the diploma provides a solid foundation for future progression into advanced certifications like CSWIP, AWS-CWI, or API, as well as higher-level diplomas in piping engineering and quality management. Learners can also pursue specialized training in advanced NDT techniques or broaden their expertise with safety certifications such as NEBOSH or IOSH, opening opportunities for supervisory and managerial roles in QA/QC and engineering projects.
