The Canadian Welding Bureau, through CSA Standards W47.1, [3] W47.2 [4] and W186, [5] specifies both a WPS and a Welding Procedure Data Sheet (WPDS) to provide direction to the welding supervisor, welders and welding operators. The WPS provides general information on the welding process and material grouping being welded, while the WPDS ...

The Canadian Welding Bureau is a certification and registration organization for companies involved in the welding of steel structures. Welders in Canada are required to be retested every two years by the Canadian Welding Bureau. The CWB Group was formed in 1947 to administer the then, new W47.1 welding standard for structural steel.
This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]
In addition to welders and welding machine operators, there are also schemes to independently certify welding inspectors and related specialities. The duties of the welding inspector are described in ISO 14731; [12] however the requirement for inspector certification are not standardized, so there are differences in requirement between the various schemes.
Data blocks of 4,000 points of electrical data are collected four times a second and converted to signature images. After image processing operations, statistical analyses of the signatures provide a quantitative assessment of the welding process, revealing its stability and reproducibility and providing fault detection and process diagnostics ...
Examples of high-risk jobs where a written permit-to-work procedure may need to be used include hot work (such as welding), confined space entry, cutting into pipes carrying hazardous substances (breaking containment), diving in the vicinity of intake openings, and work that requires electrical or mechanical isolation.
CCOHS was created in 1978 by an Act of Parliament – Canadian Centre for Occupational Health and Safety Act S.C., 1977–78, c. 29. The act was based on the belief that all Canadians had "...a fundamental right to a healthy and safe working environment".
