Provides a standardized procedure for the testing and qualification of solderers. CDA has utilized existing accepted trade practices and standards to create an effective qualification standards and information guide that can be used by local unions training centers or contractors to create their own certification programs. This will help ensure that the highest standards of…

Specifications and record-keeping forms as required by NFPA 99, Standard for Health Care Facilities; Section IX, ASME Boiler & Pressure Vessel Code, Welding & Brazing Qualifications; and ANSI/AWS B2.2 Standard for Brazing Procedure & Performance Qualifications.

While soldering and brazing of copper tube and fittings are relatively simple operations, to achieve good joints, care must be taken to follow appropriate installation practices. This reprinted article from the American Welding Society’s Welding Journal, August 2002 outlines key elements on deciding which joining process to use as well as detailed explanation of how to…

Updates the profession on the materials and methods for making soldered joints. Reviews latest solder and flux products, as well as new pressure ratings and the soldering standards that affect performance. Discusses how to evaluate solder joints, recognize flaws that may jeopardize their integrity, and how to preclude potential problems. Reprint, Reeves Journal, September 2004.

Proper soldering techniques, especially those for heat control, are essential in achieving consistent high-quality soldered joints between copper tube and new no-lead copper alloys for plumbing systems. This publication outlines common problems encountered in soldering these materials and how to covercome those problems to create durable, reliable soldered joints.
