Welding Zirconium. The article provides an overview of publications on arc welding of zirconium and its alloys for seven decades. WP-301 Welding of Zirconium and its Alloys Zirconium and its principal alloy zircaloy possess physical properties unmatched by most other metallic materials.
WP-301 Welding of Zirconium and its Alloys Zirconium and its principal alloy zircaloy possess physical properties unmatched by most other metallic materials. Zirconium and its alloys are available in two general categories. Welding-grade argon ie 10 parts per million ppm other gases 99999 percent argon is essential for primary secondary and backup shielding during GTAW as well as for purging.
Welding processes include hot wire laser overlay conduction mode laser and seam welding.
Commercial grade and reactor grade. O 1561452004 Specific 1561. EBW is undertaken under vacuum so the requirement for environmental protection is not necessary. Welding-grade argon ie 10 parts per million ppm other gases 99999 percent argon is essential for primary secondary and backup shielding during GTAW as well as for purging.
