Evaluation of the Requirements for the Approval of Weld through Primers

Abstract

In order to consider a specification for weld through primers, certain parameters were investigated. The effects of different surface treatments and different types of primers on the surface resistance were determined. Welding consistency tests, as evaluated by shear strength, X-ray and metallographic examinations, were carried out. A corrosion test was developed and used to evaluate the effect of weld through primers in minimising corrosion. The overall assessment was that when using some weld through primers, satisfactory weld quality could be maintained. However, these primers, although reducing the tendency for corrosion, were not completely effective as corrosion inhibitors.
