Characteristics | CH-70 is a low hydrogen type electrode for hard-surfacing machine parts which are subjected to metal to metal abrasion or earth and sand abrasion. It is difficult to do machining. |
Notes on usage | (1) Preheat at 150℃ and over in general. (2) In case of multi-layer build-up welding or welding mother plates with hardening property, under-lay with low hydrogen type electrodes for mild steel. (3) Dry the electrodes at 300~350℃ for 30~60 minutes before use. |
