Stick Electrodes |Heat Resistance Steel | Chosun Welding CM-76

Applications

• Welding of 0.5%Mo steel used for high temperature and high pressure boilers, chemical and oil refining industries.

Characteristics

• CM-76 is a low hydrogen type electrode for all-position welding. which provides the weld metal containing 0.5%Mo.

Notes on usage

• (1) Dry the electrodes at 325~375℃ for about one hour before use.
• (2) Preheat at 100~200℃ and postheat at 620~680℃.
• (3) Adopt back step method or strike the arc on a small steel plate prepared for this particular purpose to prevent blowholes at the arc starting
• (4) Keep the arc as short as possible
