MOISTURE ABSORPTION CHARACTERISTICS OF ELECTRODES FOR WELDING HIGH YIELD STRENGTH STEELS

The present investigation was conducted to evaluate the moisture-absorption characteristics of low-hydrogen-type electrodes recently manufactured by a number of different suppliers. The object of the investigation was to determine the moisture content of these electrodes as-removed from their shipping containers and to determine the length of time after baking that these electrodes can be exposed to atmospheres with high relative humidities and still maintain a satisfactorily low coating moisture content. The results showed that the manufacturers of the electrodes studies were in compliance with the American Welding Society (AWS) specifications on the total moisture contents permitted in the coatings of electrodes supplied in hermetically sealed containers. The results also showed that a wide variation exists in the moisture-absorption rates of the various brand-name electrodes representing a given AWS type. Although some electrodes absorbed little moisture for extended exposure times, other electrodes absorbed moisture very rapidly. Thus, on the basis of the present study, the current U. S. Steel suggestions for drying, storing, and handling low-hydrogen-type electrodes should be followed.
