What are the skills of hardfacing process for wear-resistant alloy powder blocks?
The hardfacing of wear-resistant alloy powder block is mostly made by carbon arc surfacing. General selection of graphite or carbon arc surfacing carbon rod and plate electrodes, which has good conductivity, high melting point;
Because the carbon containing ash, a graphite resistor 2-3 times, so the use of graphite electrode is better.
The power supply adopts the DC arc welding machine with steep drop characteristic, adopts the positive connection method, the electrode is negative, and the electrode is a high strength spectrum pure graphite rod,
