INTERVENTION REPORT

Welding procedure qualification comparative between AWS D1.1 and D14.1 Both standards has requierements for prequalified welding procedure specifications and essencial variables. When all of the requierements for the prequalifications of WPS is respected, there no qualifications test to perform. When there a requierement not respected, qualification test must be done and the WPS is produced to weld with all essencial variable as per qualification records.

There many small difference in prequalification requierements and essencial variables between the standards AWS D1.1 and D14.1. In this report, only the relevant differences and applicable part of the standards are specified.

First: In AWS D14.1 part 9.1.4, it is indicate that the welding procedure qualified under specification AWS D1.1 or ASME for equivalent welding shall be acceptable.

With this point, we consider that the WPS # PQR-GMAW-3-CS/FCAW-G is acceptable as per ASW D14.1 standard. This WPS is conforming to the AWS D1.1 standard.

Difference of material to weld In the case of lifting device, the material to weld on drawing of welding map 14875 is material A572 gr.50 with thichness of 4 and 5 inches. The qualification tests in WPS # PQR-GMAW-3-CS/FCAW-G were performed with material A36 with thickness of 1 inch.

In the AWS D1.1 table 3.1, The material of qualification test (A36) and material to weld (A572 gr.50) are in same class. The essencial variable is respected.

In the AWS D14.1, the material to weld (A572 gr.50 higher that 2 inch) is not in table 1 for weldability classification. In this case, the essencial variable and requierement for prequalification are not respected. The standard AWS D14.1 require qualification test with the material to weld.

In the AWS D14.1, the material to weld (A572 Gr.50 greater than 2 inch) is not in Table 1 for weldability classification. In this case, the essential variable and requirement for prequalification are not respected. The standard AWS D14.1 require qualification test with the material to weld.

When all of the requierements for the prequalifications of WPS is respected, there no qualifications test to perform. When there a requierement not respected, qualification test must be done and the WPS is produced to weld with all essencial variable as per qualification records.

There many small differences in prequalification requierements and essencial variables between the standards CSA W59 and D14.1. In this report, only the relevant differences and applicable part of the standards are specified.

In this case, the welding procedure specifications (WPS) submitted are prequalified as per CSA W59 section 10.

In section 9.1.1 of AWS D14.1, Joint welding procedures that conform in all respects to the provisions of Section 4, Base Metals; Section 6, Weld Joint Design; Section 7, Workmanship; and Section 8, Processes and Filler Metals, shall be deemed prequalified and are exempt from tests or qualifications.

The drawing and submitted WPS verified for conformance to these sections of AWS D14.1 standard.

Section 4: Base material; Material to weld in drawing and in WPS submitted are in accordance with this section of standard.

Section 6: Weld joint design: Joint design for weld in drawing and in WPS submitted are in accordance with this section of standard.

Section 7: Workmanship: Applicable parameters includes in drawing and WPS submitted are in accordance with this section of standard.

Section 8: Processes and filler metal: Applicable parameters includes in drawing and WPS submitted are in accordance with this section of standard.

Note: In sections 7 and 8, there clauses for fabrication not includes in drawing or WPS, these clauses are however similar to the clauses includes in CSA W59 standard sections 4 and 5 that was use for fabrication of wicket gate handling devices.

Welding procedure FC-P-06 This procedure is in accordance with CSA W59 standard. This procedure is appropriate to weld fillet joints at drawings.

Welding procedure FC-P-02 This procedure is in accordance with CSA W59 standard. This procedure is appropriate to weld groove weld of counterweight in drawing H1039500 MEI 82-313 FTB rev.B.

Welder Qualifications Welder qualifications of Jean-Michel Desfosses, François Desfosses, Clement Roberge, Dany Côté and Michel Beaucage found conforming to CSA W47.1 and are appropriate to weld joints at drawing with welding procedures submitted.

The welder qualification process is very similar between the CSA W47.1 and AWS D14.1. There some small differences such as:

- Minimum leng of test plate is 175 mm in AWS D14.1 and 150 mm in W47.1;

- Range of thickness qualified vs thickness of test plate have small difference;

- Period of qualification: 2 years for CSA W47 and indefinitly in AWS D14.1 if welder use regulary the welding process.

Welding inspection (Visual and magnetic particles) The welding inspection was performed on handling devices as per AWS D1.1.

Welding inspection procedures PE 400 (visual inspection) and PE 200 (magnetic particles inspection) found conforming to the ASME standard (section V).

Welding inspector qualifications (CWI) of Ian Trudel and Stephane Trudel found conform to SNT-TC-1A standard in appropriate methods.
