CSA W186 Welding of Reinforcing Bars
This standard sets the criteria for companies seeking certification for Welding of Reinforcement Bars in Reinforced Concrete Construction for steel. Companies who wish to be certified under this standard are required to qualify their Welding Supervisors and their Welding Engineers, submit for review and approval their Company’s Welding Procedures and qualify their Welding personnel (welders or operators).
ÒõAPPµ¼º½ Process
ÒõAPPµ¼º½ to CSA Standard W186 is obtained upon completion of the following elements.
ÒõAPPµ¼º½ Steps
To begin, you must complete and submit Form 150 - Application for ÒõAPPµ¼º½.
Once you've received your quotation letter, and paid your initial application fee, you can proceed with the steps below.
Several forms must be completed and returned to the CWB. This will help us identify your personnel and list the experience of your welding supervisors and engineers.
- Form 151 – List of Personnel (required with or prior to Forms 155 / 159 being submitted)
- Form 155 – Welding Supervisor Resume
- Form 159 – Welding Engineer Declaration (required for Division 1 or 2 companies, if applicable)
All forms are to be forwarded to forms@cwbgroup.org for processing. You will receive an acknowledgment email once processing is completed.
Each company must employ an adequate number of Welding Supervisors to control its welding operations. Each Welding Supervisor must have welding related experience and complete written examinations on welding symbols, weld faults, quality control and inspection methods and the following standard(s):
- CSA Standard W186, Welding of Reinforcing Bars in Reinforced Concrete Construction
In addition each Welding Supervisor is given a brief verbal examination on the following subjects:
- welding equipment
- drawings
- welding procedures
The qualification examinations on welding symbols, weld faults and quality control and inspection methods may be waived if the Welding Supervisor holds a diploma from a recognized course in welding fundamentals or weld quality control and inspection. Examinations are normally held in each of ÒõAPPµ¼º½'s regional offices. Seminars are provided occasionally on each of the subjects required for qualification. To help Welding Supervisors prepare for the exams, a copy of the applicable CSA Standards plus a number of study guides are provided to each applicant company.
Each company applying for certification must designate and qualify a Welding Engineer who is responsible for welding related activities as specified by the company. The engineer(s) must meet the minimum educational and experience requirements of the applicable standard and complete the written examinations on the following standards:
- CSA Standard W186, Welding of Reinforcing Bars in Reinforced Concrete Construction
If the educational requirements of the applicable standard have not been met, additional courses may be required. Each designated engineer's educational and experience qualification information must be submitted to the ÒõAPPµ¼º½ for review. An interview will be conducted to review the material submitted and discuss the engineer's experience and educational background.
Each company must prepare and submit to the ÒõAPPµ¼º½ for acceptance, a detailed set of welding procedures consisting of:
- Welding Procedure Specifications (WPS) for each welding process used.
- Welding Procedure Data Sheets (WPDS) for each welding process used, joint configuration, electrode type, etc.
In certain circumstances, based on the welding procedure submission, procedure qualification tests may be required to verify the acceptance of the welding procedure data sheets.
All welders, welding operators and tack welders employed by the company must be tested for the processes and positions of welding which they use in production.
From time to time, a ÒõAPPµ¼º½ Representative will visit each company to complete an audit report and provide assistance. Once all of the above are completed and all other items such as electrode storage facilities (shop and field), general appearance of welding, etc. are acceptable, then the company is recommended for certification.
Upon satisfactory completion of the final review procedure, the company is issued a Letter of ÒõAPPµ¼º½, Letter of Validation and a Document of ÒõAPPµ¼º½. Permission is also granted to use the ÒõAPPµ¼º½ registered trademark on the company's letterhead and promotional material.
