🌍 International Standards – Foundation of Stable Quality

At NFK, we have established and implemented the Welding Procedure Specification (WPS) according to the EN ISO 15614-1:2004 standard. This is an important international benchmark, certified by Lloyd’s Register Energy Japan, to ensure that all NFK welding products achieve high reliability and consistency.

🔧 Main Content

• Welding Process: TIG, without filler material, suitable for thin materials.
• Material: SUS304, thickness of only 0.25 mm – requires precise welding techniques and strict heat control.
• Preparation Method: Mechanical processing and surface cleaning to ensure the weld is free from contaminants.
• Welding Parameters:
  • Current: 16–18 A
  • Voltage: 8–10 V
  • Travel Speed: 55–60 cm/min
  • Torch Angle: 85°
  • Gas Shielding: 99.9% pure Argon, flow rate of 7 L/min, combined with copper backing to stabilize the weld.
• Inspection: Certified by Lloyd’s Register Energy Japan through WPQR (Welding Procedure Qualification Record), confirming the practical applicability of the procedure.
