Description:
CHE505G
is a high
cellulose sodium type electrode. The electrode shows a very good performance
in welding of all positions and vertical-down, overhead. It forms on double
sides by one side welding. It is suitable for welding root passes, hot
passes, filler and cover passes as well as for capping of huge diameter high
press pipelines fabricated by X60, X65 and X70 grade steel and similar
structures. Keeping the electrode in dry condition. The electrodes do not be
redried before welding. In welding small current is recommended and swaying
broad should be less than 2.5 times of diameter of the electrode.
