CHE5050GX
Cellulose Electrode for High Press Pipeline

CHE5050GX is a high cellulose sodium type electrode.The electrode shows a very good performance in welding of all positons and vertical-down,overhead.It forms on double sides by one side welding.It is suitable for welding root passes,filler and cover passes as well as for caping 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.
