CHE555GX

Cellulose Electrode for High Press Pipeline

CHE555GX is a high tensile strength cellulose type electrode. Very good performance can be obtained by all position welding, overhead and vertical down welding. Especially suitable for fabricating huge diameter high press pipelines fabricated by X70 or X80 grade steels. Backing weld, filling welding and lap welding could be operated and forming on double sides by one sides welding. Keeping the electrode in dry condition. The electrodes do not be redried before welding. Small current is recommended in welding and swaying broad less than 2.5 times of diameter of the electrode.
