CWB CERTIFICATION/ CWB CERTIFICATION/ QUALIFICATION QUALIFICATION SERVICES SERVICES CANADIAN WELDING CERTIFICATION AN OVERVIEW Canada, like many countries around the world, has specific rules and regulations governing the construction of buildings and their related structural components. In Canada, companies doing such work are governed by the National or Provincial Building Code(s) and CSA Standard S16 Design of Steel Structures. These codes and standards are mandatory and apply to all Canadian welding, fabricating or erection companies, as well as US or International companies, working with or providing applicable structural welded products for use within Canada. In addition to the above, there are also several additional product and safety codes that include requirements for CWB Certification. For over 60 years, the CWB, as the administrators of the relevant CSA standards in support of the above, has been providing valuable assistance and guidance for companies seeking certification and welder qualification. ABOUT CWB CERTIFICATION/ QUALIFICATION The work CWB does on behalf of our clients can be divided into five main categories: 1 Certification Services for Welding Professionals and Welding Companies, comprising of: 1 CWB Company Certification: Welder, Welding Supervisor, Welding Engineer Qualifications, and CWB Welding Inspector Certification 2 3 5 CWB Qualification of Welding Procedures CWB Certification of Electrodes and Filler Metals Qualification and Certification of Canadian Welding professional and Welding Companies to International requirements (eg. IIW/ ISO 383) CWB Stud base Qualification 1
CWB CERTIFICATION/ QUALIFICATION SERVICES CWB COMPANY CERTIFICATION Any company that is CWB Certified has undergone a review and qualification process to ensure that they meet the requirements for welding companies as specified in CSA Standards W7.1, W7.2, W55.3 or W186. Within CSA W7.1 and W7.2, a company may be Certified in one of three Divisions, based on the type of work to be undertaken, and the customer or end user. Within each Division, the CSA Standards provide clear requirements with respect to the personnel, procedures, as well as workmanship, as verified though auditing, that will be required. Under the Standards/ Divisional requirements, each Certified Company is required to employ an adequate number of Welding Supervisors, and Welding Engineers with welding related experience, to control welding operations. Although not mandated by the above noted Standards, there may be an additional requirement (such as under CSA W59, another very common CSA Standard) for Certified Welding Inspectors to be also employed by a CWB Certified company. 2 CWB WELDER, WELDING SUPERVISOR AND WELDING ENGINEER QUALIFICATION Starting at the welder level, all welders working for a CWB Certified company must be qualified by the CWB once every two years. This is a practical test administered by a CWB certification representative that normally takes place at the welder s place of employment, using a test plate provided and evaluated by the CWB. Further, depending on the company s CSA Division, there may be requirements for welders to be designated by their employer as Welding Supervisors. All Welding Supervisors must successfully complete written CWB examinations on welding symbols, weld faults, quality control and inspection methods and the applicable standard(s) and demonstrate relevant experience before they can be qualified. In addition, depending on the scope of work being done, there may be an additional requirement under CSA Standards for a CWB Qualified Welding Engineer. To become a CWB Welding Engineer it requires suitable experience and knowledge and writing and passing examinations on the standards administered by the CWB. To help individuals acquire the required qualification the CWB Institute runs regular online and classroom courses for Welding Supervisors as well as providing self study material for prospective Welding Engineers.
CWB CERTIFICATION/ QUALIFICATION SERVICES CWB QUALIFICATION OF WELDING PROCEDURES Under CSA Standard W7.1, W7.2, W186 and W55.3, all CWB Certified Companies are required to submit their welding procedures to CWB for evaluation and approval to ensure they meet the requirements of the governing standard. This must be done before the start of any work, as outlined within the applicable Standard(s). CWB WELDING INSPECTOR CERTIFICATION Mandated by some Canadian Codes and Standards a CWB Certified Welding Inspector is always a valuable asset to any company interested in delivering quality products within a quality management system such as ISO 9001 or ISO 383. All Welding Inspectors are trained in the theory and application of visual inspection with respect to welded assemblies and must pass both a CWB practical and theoretical exam to become certified. Training for Welding Inspectors (Inspector Level 1,2 & 3) is available through the CWB Institute. Beyond visual inspection the CWB Group can also provide training for various Non-destructive Testing methods (NDT) that complement and extend the skill set of CWB Certified Inspectors. CWB CERTIFICATION OF ELECTRODES AND FILLER METALS Certification of welding electrodes and filler metal are required in Canada when welding under CSA Certification Standards. It is also required by certain other codes and standards in Canada, as well as when specified by users as part of their quality requirements. 3
CWB CERTIFICATION/ QUALIFICATION SERVICES QUALIFICATION AND CERTIFICATION OF CANADIAN WELDING PROFESSIONAL AND WELDING COMPANIES TO INTERNATIONAL STANDARDS As the Authorized National Body (ANB) for the International Institute of Welding (IIW), the CWB is able to provide several levels of internationally recognized certification and qualification for welding professionals, as well as welding companies. Within the scope of the IIW ANB agreement, the CWB can provide: Training Facility Certification For Canadian trade schools, colleges or other post secondary institution who are looking to grant IIW diplomas, the CWB can grant approval as an Authorized Training Body (ATB). Company Certification For Canadian companies looking to be certified to IS0 383 standards under IIW s internationally recognized Quality Requirements for Welding Standard. Welding Professional Qualification - diplomas in : International Welding Engineer (IWE) International Welding Technologist (IWT) International Welding Specialist (IWS) International Welding Practitioner (IWP) In addition, the CWB can provide inspector code endorsement and qualification relating to: American Bureau of Shipping (ABS) American Society of Mechanical Engineers (ASME) Canadian Standards Association (CSA): Z662 W7.1 W59 American Petroleum Institute (API)
CWB CERTIFICATION/ QUALIFICATION SERVICES CWB STUD BASE QUALIFICATION Fabricators performing stud welding under CSA Standard W59 are required to use only qualified studs through CWB qualification program. Studs that are shop or field applied must be qualified by the manufacturer through CWB to the extent of one of the following codes: CSA W59, AWS D1.1, AWS D1.5 or AWS D1.6. Qualification of studs will ensure that the stud manufacturer has successfully met the tests and the quality system requirements as specified in the applicable standard. 5
