4 for the Welding Industry What are they? An Expert Technology Tool (ETT) is a medium for diffusion and take-up of technological information based on global research and development (R&D) and experience to improve industry performance. It can be formatted as a hard copy, software (fixed, interactive or modifiable), audiovisual (videos and sound tapes) or physical samples. It can be complemented by face-to-face interaction, on-site and remote assistance, training modules and auditing programs. The diagram overleaf and the information below show how the WTIA has introduced a group of ETTs to help companies improve their performance. ETTs and the SME how can they help my Total Welding Management System? A Total Welding Management System (TWMS) is a major ETT with supporting ETTs created specifically to assist Australian industry, particularly those Small to Medium Enterprises (SMEs) that do not have the time or finance to develop an in-house system. These companies, however, are still bound by legal requirements for compliance in many areas such as OH&S, either due to government regulation or to contract requirements. The TWMS developed by the WTIA can be tailor-made by SMEs to suit any size and scope of operation, and implemented in full or in part as required. What is Total Welding Management Total Welding Management comprises all of the elements shown in the left-hand column of the table shown overleaf. Each of these elements needs to be addressed within any company, large or small, undertaking welding, which wishes to operate efficiently and be competitive in the Australian and overseas markets. The Total Welding Management System Manual (itself an Expert Technology Tool) created by the WTIA with the assistance of industry and organisations represented within a Technology Expert Group, overviews each of these elements in the left-hand column. It details how each element relates to effective welding management, refers to supporting welding-related ETTs, or, where the subject matter is out of the range of expertise of the authors, refers the user to external sources such as accounting or legal expertise. Knowledge Resource Bank The other columns on the diagram overleaf list the Knowledge Resource Bank and show examples of supporting ETTs which may, or may not, be produced directly by the WTIA. The aim, however, is to assist companies to access this knowledge and to recognise the role that knowledge plays in a Total Welding Management System. These supporting ETTs may take any form, such as a Management System e.g. Occupational Health and Safety Management System (OHSMS), a publication e.g. WTIA Technical Note (TN) or Guidance Note (GN or TGN), a video or a Standard through to software, a one-page guidance note or welding procedure. Clearly, ETTs such as WTIA Technical Notes, various Standards, software, videos etc are readily available to industry. The group of ETTs shown overleaf have been tailor-made to suit the water industry sector. A company-specific Knowledge Resource Bank can be made by the company omitting or replacing any other ETT or Standard. Total Welding Management for Industry Sectors Total Welding Management Systems and the associated Knowledge Resource Bank have been developed for the mining industry, tailored to address the particular issues of that industry and to facilitate access to relevant resources. A company-specific Total Welding Management System can also be made by the company adding, omitting or replacing any element shown in the left hand column or ETT or Standard shown in the other columns. This approach links in with industry needs already identified by existing WTIA SMART Industry Groups including the SMART Mining Industry Group. Members of these groups have already highlighted the common problem of industry knowledge loss through downsizing, outsourcing and privatisation and are looking for ways to address this problem. The concept of industry specific Total Welding Management Systems and Knowledge Resource Banks is being extended based on the results of industry needs analyses. The resources within the Bank will be expanded with the help of Technology Expert Groups including WTIA Technical Panels. Information needs will be identified for the specific industry sectors, existing resources located either within Australia or overseas if otherwise unavailable, and if necessary, new resources will be created to satisfy these needs. How to Access ETTs Management System ETTs, whether they are the Total Welding Management Manual (which includes the Quality Manual), OHSMS Managers Handbook, Procedures, Work Instructions, Forms and Records or Environmental Improvement System, can be accessed and implemented in a variety of ways. They can be: Purchased as a publication for use by industry. They may augment existing manuals, targeting the welding operation of the company, or they may be implemented from scratch by competent personnel employed by the company; Accessed as course notes when attending a public workshop explaining the ETT; Accessed as course notes when attending an inhouse workshop explaining the ETT; Purchased within a package which includes training and on-site implementation assistance from qualified WTIA personnel; Accessed during face-to-face consultation. Downloaded from the WTIA website ETTs created by the WTIA are listed in the back of WTIA Technical Notes. Call the WTIA Welding Hotline on for further information.
