ON-SITE WELDING OF PIPELINES USING CELLULOSE AND BASIC COATED STICK ELECTRODES IN THE VERTICAL-DOWN POSITION

Following a brief review of the development of pipe steels, cellulose and basic coated electrodes for vertical-down welding are compared with regard to their suitability for use in pipeline construction. In addition to economic considerations <deposition rates>, particular attention is given to the hydrogen content and notch impact strength of the weld metal. It is found that, in comparison with cellulose-coated, vertical-down electrodes, basic electrodes deposit a weld metal which is tougher and has a lower diffusible hydrogen content. On the other hand, cellulose-coated stick electrodes can be expected to give higher pipe-laying rates.
