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?

H 13 is hot-working die steel, and the standard GB/T 1299-2000 is implemented. Uniform digital code A20502；; Grade 4cr5mosiv1; Alloy tool steel, referred to as alloy steel for short, is a kind of steel formed by adding alloying elements on the basis of carbon steel. Among them, the combined steel includes: steel for measuring tools, steel for impact tools, cold-working die steel, hot-working die steel, non-magnetic die steel and plastic die steel.

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.

Cobalt-based surfacing covered electrode D802 and D812 "—— Silver-silver covered electrode (namely silver solder, silver welding wire, silver welding ring, silver weldment and silver solder paste )——— D918 Wear-resistant covered electrode —— Wear-resistant powder spraying of nickel-based alloy.
