CSA-B613 – Private Residence Lifts for Persons With Physical Disabilities Welding Requirements

Welded Fabrication CSA Standard B613 provides the following requirements: 4.11 Welding: All structural welding shall be performed in accordance with the following: (a) steel — CSA W59; and (b) aluminum — CSA W59.2. CSA Standards W59 and W59.2 provide guidance on weld design, fabrication techniques, inspection and other key considerations around welding for steel and aluminum respectively. CSA Standard W59 requires that contractors performing work under this standard be certified under the requirements of CSA Standard W47.1 unless the Engineer of record approves the contractor for the work to be undertaken. CSA Standard W47.1 provides requirements for the qualification of welders and welding operators, welding procedures and welding supervisory and engineering personnel. CSA Standard W59.2 requires contractors performing work to be certified under the requirements of CSA Standard W47.2. CSA Standard W47.2 provides requirements for the qualification of welders and welding operators, welding procedures and welding supervisory and engineering personnel. An organization meeting the requirements of CSA Standard W47.1 and / or CSA Standard W47.2 will have qualified welders, accepted welding procedures and accepted supervisory/engineering personnel. All elements of the welding operation will be independently verified by the Canadian Welding Bureau on an on-going basis. Please note that there are no domestic or international equivalents to CSA Standard W47.1 or CSA Standard W47.2. Other national systems, such as that of the American Welding Society (AWS) do not include key concepts such as independent and ongoing verification and welding supervisors/engineers. The CWB strongly cautions the reader around accepting substitutions; doing so may contravene the intent of CSA Standard B613 and place public safety at risk. Welding Inspection CSA Standard W59 requires that visual weld inspection be completed by certified welding inspectors or a welding inspection organization following the requirements of CSA Standard W178.2, respective CSA Standard W178.1. It also requires that CSA Standard W59 be followed for the acceptance criteria for all welds. It should be noted that CSA Standard W178.2 has individual “product categories” that inspectors may qualify to, including one for CSA Standard W59.
