1. Zirconium Filler Wire
2. Grade and Size
R60702: This is a standard model of pure zirconium welding wire, suitable for welding of pure zirconium.
R60704: This is a zirconium-niobium alloy welding wire, suitable for welding zirconium alloy materials, such as ZR-2, ZR-4, etc.
Standards: AWS A5.24
3. Classification of zirconium filler wires:
3KG per coil or 10kg per coil
DN100 DN200 DN300 plastic spool
4. Composition of zirconium 702
The chemical composition of zirconium 702 mainly includes elements such as zirconium (Zr), nickel (Ni), iron (Fe), silicon (Si), manganese (Mn), aluminum (Al), tin (Sn), and oxygen (O), with zirconium content of 70% and nickel content of 2%.
5. Why need to choose zirconium wire on a spool for welding?
Q: 1. What are the precautions for welding zirconium materials?
A: After welding, zirconium materials must undergo visual inspection. The weld seam and heat-affected zone must not have slag inclusions, pores, cracks, undercuts, fusion spatter, or color changes beyond the specified range.
Q: 2. What are the testing methods for zirconium welding?
After welding, 100% PT inspection must be carried out on both sides of the weld seam. If the back cannot be approached, the surface of the base weld must undergo 100% PT inspection.
Q: 3. What are the commonly used zirconium welding wires?
A: Zirconium welding wire has three common forms: coil wire, straight wire, and wire on a spool. The commonly used outer diameter sizes include 1.0, 1.5, 2.0, 2.5mm, etc
