Materials:
Manufacturing and repairing of cutting tools, e.g. for turning, planning, milling, reaming, drills, etc.
Caution :
In order obtain optimum results, deposit three layers one on top of the other. Before welding, preheat the work piece up to 600°C-700°C and maintain this temperature during welding. Weld at the lowest possible.
Do not weld the AMA 1105V electrode if the coating is damaged.
