When spot ultrasonic examination representative of a given unit length of weld shows defects, the defects shall be traced for repair and two additional spots shall be examined within the same unit length of weld to properly sample the remainder of the original unit length of weld. Chapter 2, A review of fatigue strength improvement techniques.
When welding stainless steel, other standards such as AWS D1. Appendix H, which is a mandatory appendix dealing with the qualification of studs, has seen significant changes. Methods to enhance the fatigue resistance of welds are recognized.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the ww59 explanatory or informative material.

CSA W59 Welded Steel Construction
Clause 1 acknowledges that provisions for metal-cored arc welding are now included in the Standard. It now consists of the following pages: Fatigue strength of welded structures. The evaluation shall compare the physical size of the discontinuity with the acceptance standard defined for visual inspection. The appendices of the previous edition of W59 have generally been reviewed for clarity. Welded Steel Construction Metal Arc Welding — originally published August The following revisions have been formally approved vsa are marked by the symbol delta csw the margin on the attached replacement pages: Canadian Standards Association — All rights reserved.
Design wise I think there are a few differences between the two codes. The previous Appendix N on w95 capacities, loaded in shear has been deleted and replaced with an appendix providing a better understanding of the modes of metal transfer in gas metal arc welding, especially in light of the prequalification of joints using the spray transfer mode.
The strength of fillet welds can now be increased, depending upon the direction of loading. Additional fatigue detail categories have been added. Allowances for the use of an alternative ultrasonic technique and radiographic cda systems have been added.
Is your application for offshore structures or onshore structures? In Clause 10, all the figures have been reviewed for consistency.
October Replaces p. Several steels have been added to the prequalified list. Peening Improves Fatigue Life. Nevada – Section The index point location procedure is described in Clause 8. International efforts on fatigue of welded construction. This Standard does not cover welding of stainless steel. Fatigue is recognized as being load-induced or distortion-induced. I have recieved an inquiry to qualify welders and procedures, fabricate and inspect using Canadian Welding Bureau Standards.
In the case of any conflict between AWS D1.

The concept of a flare bevel fillet weld is introduced. Not logged in American Welding Society Forum. The provisions of this Standard are not intended for use with steels having a css minimum yield strength over MPa psi. The tip of the electrode must be kept sharp and clean.
Changes to the Scope reflect the renaming of Clause 12 from Dynamically Loaded Structures to Cyclically Loaded Structures, to better reflect the emphasis of Clause 12 on the repetitive nature of structural loadings fatigue rather than the rate at which the loading is applied.
