UNLOCKING THE POTENTIAL OF NICKEL ALLOYS : CORROSION RESISTANCE, MECHANICAL STRENGTH, AND WELDING CONSIDERATIONS

Nickel and its alloys offer outstanding corrosion resistance and impressive mechanical properties, which remain consistent across a wide temperature range, from high (200-1100°C/ 400-2000°F) to low temperatures (-196°C, or even lower). These alloys are typically categorized into two groups : solid-solution-strengthened alloys and precipitation-hardening alloys. Weldability tends to be better for the former category compared to precipitation-hardening alloys.

When welding nickel and its alloys, it's essential to consider their unique characteristics :

  • Low thermal and electrical conductivity of the material.
  • Fluidity issues in the weld pool, which can lead to lack of fusion and penetration in the joints.
  • Porosity and oxide inclusion.
  • Susceptibility to hot cracking, particularly in the center of the joint or crater, due to potential surface oxides and contaminants.
By addressing these considerations, you can optimize the welding process for nickel alloys and achieve high-quality welds that meet performance requirements.
