1, mold repair, its material is H 13, what specifications and models of argon arc welding machine are commonly used? 2. What type of welding wire is it?
You can buy H 13 welding wire.
FW-3 102 Alloy Wear-resistant covered electrode Instructions for Use: National patented products, products under the national key promotion plan of scientific and technological achievements. Suitable for high temperature abrasive wear and small angle erosion wear of fine particles. Single layer surfacing can meet the performance requirements; Use FW-2 10 1 to surfacing the transition layer. The maximum operating temperature is 1000℃. Hardness of surfacing layer: 20℃ HRC 66-70 600℃ HRC 60-65 800℃ HRC 55-60 Typical application fields, working conditions and components: machinery and equipment worn at high temperature in iron-making, coking, sintering, cement and other industrial fields. The tooth crown, grate plate and rotary distribution chute of blast furnace of sintering single-roll crusher in service at high temperature are used for surfacing welding, and the wear resistance effect is remarkable.
