Description:
CHE425G is a high cellulose sodium type electrode. The electrodes show
a very good performance in welding as all positions and vertical down, overhead,
and forming on both sides. Keeping the electrode in dry as it is damped easily,
The electrodes do not be retried and in welding, should use small current, and
swaying broad less than 2.5 times of diameter of the electrode.
|
Applications:
Suitable for vertical down welding root passes, hot
passes, filler and cover passes as well as for capping of normal pipe steels and
similar structures.
