The formation of a Welding Coordination Team (WCT) and the nomination of a Responsible Welding Coordinator (RWC) in a company is no longer a new concept. The RWC is called for by AS/NZS ISO 3834:2008 Quality Requirements for Fusion Welding of Metallic Materials and ISO 14731:2006 Welding coordination – Tasks and responsibilities and links to the roles of Designer, Contracts Person, Welding Supervisor, Welding Inspector, Fabrication Inspector and NDT Personnel commonly found in Australian companies. Companies, particularly owners/users, around Australia are calling for their supply and service companies to have implemented the International Institute of Welding (IIW) Manufacturers Certification Scheme (MCS) According to ISO 3834 (IIW MCS ISO 3834). Thus many such companies in Australia, especially SMEs, are now working towards certification, not only to satisfy their customers’ requirements and national and international product standards but also to enhance their welding productivity, quality and business competitiveness.
In many companies and workshops, the welding coordination roles and tasks are, in fact, typically shared amongst a number of people, as shown in Figure 1 and Table 1. Collectively these people form the WCT responsible for welding quality, under the leadership of the nominated Responsible Welding Coordinator (RWC).
As a team, they are responsible for not only welding quality and management, but also productivity, occupational health, safety and rehabilitation (OHS&R) and management of environmental issues. Each contributes their own knowledge, expertise, qualifications and certification to the team to support not only the company’s compliance to ISO 3834 and other Standards but also its overall efficiency and competitiveness in the market place. The certification requirements for each person are shown below.

All Welding Coordination Personnel
For all tasks assigned, welding coordination personnel shall be able to demonstrate adequate technical knowledge to enable such tasks to be performed satisfactorily.
The following factors should be considered:
The extent of required manufacturing experience, education and technical knowledge should be decided by the organisation and will depend on the assigned tasks and responsibilities.
Responsible Welding Coordination (RWC) Personnel
A RWC must be nominated by the organisation. The responsibilities of the RWC to carry out, supervise and/or oversee welding engineering tasks will be clearly defined by the organisation. He/She must be authorised to sign on behalf of the organisation in contractual welding quality related matters, e.g. accepting technical welding requirements, or verifying that the organisation has complied with all relevant quality considerations in the production of the product.
Three different levels of RWC described in ISO 14731. The selection of RWC depends mainly on the variability and technical complexity of the welding coordination and responsibilities required.
Welding coordination personnel with full technical knowledge for planning, executing, supervising and testing of all tasks and responsibilities in welding fabrication, construction, repair, maintenance etc.
For example, where a broad range of materials, processes, thicknesses, procedures & NDT requirements is involved, and a wide variety of products are to be manufactured to differing codes, major fabrication projects etc.
Welding coordination personnel with technical knowledge sufficient for planning, executing, supervising and testing of the tasks and responsibilities in welding fabrication within a selective or limited technical field.
For example, where welding processes, procedures, materials and products do not change significantly etc.
Welding coordination personnel with technical knowledge sufficient for planning, executing, supervising and testing of the tasks and responsibilities in welding fabrication within a limited technical field involving simple welded constructions
