In 1992, a Welder Qualification Sub-Committee in SWS was set up under the Chairmanship of Mr Seiichi Inoue, Managing Director of Chiyoda Singapore Pte Ltd. The objective of this sub-committee was to set up a common welder qualification scheme that would be recognised and accepted by the industry, particularly the oil, gas and petrochemical companies, and their sub-contractors. It was agreed by all parties in the process industry, that welder qualified through this scheme, need not have to undergo repeated welder tests whenever the welders moved from one refinery/plant to another for different jobs and contracts. Hence, this set the stage for the formation of Common Welder Qualification Scheme (CWQS) in 1993.
