Welding Quality in Kenya: Application of Radiography

Abstract

In Kenya, welding services are extensively employed in both the formal and informal sectors. The needs continue to increase with increasing population, infrastructure and vehicle fleet, and economic development. Welding need is even currently very important in support of Kenya Vision 2030. This study reports some examples on the role of radiography in assessing quality of welds in Kenya in accordance with Article 2 and 22 of ASME V. Samples were acquired from both informal and formal sectors and tested for volumetric flaws using radiography method. During the sample acquisition visual inspection were carried out before and after welding, and professional Non Destructive Testing investigators witnessed the welding process on site. The study observed a wide variation in welding competency, especially in the informal sector and this has provoked efforts to widen the study with an aim of developing a comprehensive advisory report for Kenyan policy makers.
