scope:

This Standard provides the requirements for the certification of companies engaged in the fusion welding of steel and the qualification of their personnel and welding procedures.

Notes:

(1) Certification may be mandatory or voluntary.

(2) This Standard is not intended for applications governed by codes such as the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code and codes of the American Petroleum Institute (API).

The requirements of this Standard are based on the principle that a certified company has full responsibility for the quality of the welded product it produces, and this responsibility cannot be transferred to its employed or retained personnel, or to the administrator of this Standard.

This Standard governs the certification of companies. Certification pertains to the capability of the company with respect to welding. Certification should not be construed as approving any products or services of the certified company.

This Standard stipulates requirements for

(a) welding engineers;

(b) welding supervisors;

(c) tack welders, welders, and welding operators; and

(d) documentation

as defined or specified in this Standard.

The qualification requirements for tack welders, welders, and welding operators specified in this Standard are intended to demonstrate an individual's basic welding skills and to provide a means of verifying that individual's continuing ability in the fusion welding of steel.

Provisions for recognition of personnel qualified under other jurisdictions are included in this Standard.

For welding of stainless steel, the provisions of AWS Standard D1.6 may be used for the qualification of welding procedures and personnel. However, when the provisions of AWS Standard D1.6 and this Standard conflict, this Standard takes precedence.

This Standard does not address the safety issues associated with welding and welding practices.

Note: CSA Standard W117.2 addresses safety in welding and should be followed, in addition to any applicable workplace health and safety legislation in effect. It is the responsibility of the user of this Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
