1. EQUIVALENT STANDARD AND CONFORMITY
- Japanese standard: JIS DF2B-600-B
2. CHARACTERISTICS AND APPLICATION
- The GH-600 high-hardness surface resurfacing electrode is made for welding on metal surfaces that have worn out through use. The surface of the part after the restoration welding has a stable texture, high hardness, and good wear resistance.
- The GH-600 welding rod has a base coating with flour as the main ingredient, so it has a low hydrogen content and small impurities. A martensitic background is added along with rare and precious alloying elements such as chromium and molybdenum to create a high-quality hard weld that is very resistant to abrasion and impact.
- GH-600 welding rod can be welded in any position with a stable arc, strong pressure, and a well-balanced weld, and it is simple to peel and clean, making it ideal for surfaces that require high aesthetic flatness.
- After welding, the weld metal surface has a hardness of more than 55 HRC; if heat treatment steps are used, the hardness can reach 65 HRC.

7. INSTRUCTIONS FOR USE
- Fully preparing the elements of labor safety before welding. Welding power source is stable.
- When the welding rod is moist, welding is vulnerable to smoke, splashed and unstable, weld is clarified, need to dry at 200oC in 40 – 60 minutes before use.
- Removing all traces of oil, dust, dirt on the surface of the weld.
- Making sure the weld gap, bevelled edge of welding materials as prescribed to achieve strong weld.
- Selecting the welding line according to the instructions to obtain the deep weld, high working ability.
