Welding current (A) 3.2*90/110 4.0*150/180 4.0*180/210
Matters needing attention: 1. The electrode should be baked at 150ºC for 1h before welding. 2. The workpiece should be preheated to 250ºC before welding, and cooled slowly after welding.
D266 type high manganese steel wear-resistant electrode
Detailed information: D266 type high manganese steel wear-resistant electrode: suitable for surfacing welding of various crushers, high manganese rails, buckets, earth piling machines and other wear-resistant parts. Among them, molybdenum improves crack resistance and wear resistance. During surfacing welding, immediately beat or water quench while it is red hot to reduce cracks. For surfacing high manganese steel parts, first remove the wear fatigue layer or water toughness treatment. After surfacing, the hardness can reach HR≥170 Note: After welding, take advantage of the red heat to quickly cool down (such as water quenching) to prevent local shedding.
D172 surfacing wear-resistant electrode conforms to: EDPCrMo-A3-03
Description: D172 high-hardness surfacing electrode at room temperature is a chrome-molybdenum steel surfacing electrode with titanium-calcium type coating. Uses: used for surfacing gears, excavating heads, tractor scrapers, deep ploughs, mining machinery and other wear parts.
