ลวดเชื่อมเหล็กหล่อ Ni55 2.6mmx300mm SUMO
Welding Electrode Cast Iron Ni55 2.6mmx300mm SUMO
มาตรฐานคุณภาพ (Standard Compliance)
- ISO9001:2015
- Application Standard: AWS A5.15 ENiFe-CI
- ISO 1071: ENiFe-CI
- JIS Z 3252 DFCNiFe
- Cast iron welding rod with a nickel-iron alloy core and a strong reducing graphite coating. Has the characteristics of high strength, good plasticity, and low linear expansion coefficient.
Application
- Suitable for repair welding of important high-strength gray castings and ductile iron castings, such as cylinders, engine seats, gears, rollers, etc.
Welding Position
- 1G and 2F
Instructions
- The rod should be baked at 80°C-120°C for 1hours before use.
- The surfaces to be welded must be cleaned away impurities of oil contamination, rust, moisture and so on.
- When welding, hammering the weld joint to dispel stress around the welding region to avoid crack.
- To increase ability of crack-resisting and machinable, small current is recommended, meanwhile could reduce impurities to permeate the weld seam from base metal.
