During the construction of Standard Gauge Railway, it emerged that the Chinese contractor needed to import labour for welding because such skills were not available locally. This same scenario also played out when Tullow Oil pitched camp in Kenya.
So, my curiosity led to try and understand how different this kind of welding is from the JuaKali artisan and my teacher of the day was Monica, a tutor at Oil and Gas Technical Institute located in Nairobi's Industrial Area.
