Abstract:

Cellulosic-coated electrodes (primarily AWS EXX10-type) are traditionally used for "stovepipe" welding of pipelines because they are well suited for deposition of pipeline girth welds and are capable of high deposition rates when welding downhill. Extensive work was undertaken in the 1970s and 1980s to study heat affected zone (HAZ) hydrogen-assisted cracking, and guidelines were developed to avoid HAZ hydrogen cracking by controlling heat input and preheat. Improvements in steel making practice and the trend towards leaner chemistries have also helped to alleviate HAZ hydrogen cracking. In recent years, weld metal hydrogen cracking has become more of an issue with the trend towards higher-strength steels and welding with minimal or no preheat.
