Lesson 10 - Reliability of Welding Filler Metals

© COPYRIGHT 2000 THE ESAB GROUP, INC. LESSON X 10.10 CERTIFICATION OF ELECTRODES The certification of electrodes and welding wires has become more critical today, and the number of test certifications requested has increased more than ten-fold in the last several years. Conducting certification tests is a costly process, and all efforts must be made to provide accurate information to the manufacturer, so that the end-user gets the material tested to the necessary degree; no more, no less. 10.10.0.1 Welding filler metals may be certified by one of two methods: typical properties certification or actual properties certification. 10.10.1 Typical Properties Certification - Certifications showing typical chemistry and mechanical properties are provided with customer orders when so requested. These typical properties are based on the results of many tests on similar materials and on a very comprehensive, carefully controlled Quality Assurance System. An ESAB Typical Proper- ties Certificate assures that the products are tested in compliance with AWS and ASME Filler Metal Specifications. A copy of a Typical Properties Certificate for Atom Arc electrodes is shown in Figure 9. Typical certifications are supplied by the manufacturer, on a no-charge basis, by request. 10.10.2 Actual Certifications - Actual certification that each lot of a particular product shipment will meet a desired specification is normally supplied by the manufac- turer for a fee. In this case, pack- ages of each lot number of the product to be shipped will be opened and tested according to the customer’s request. TYPICAL PROPERTIES CERTIFICATE FIGURE 9
