Lastifil 900

Welding of pure nickel

AWS A5.14 : ER Ni-1 (UNS N02061)

General description:

Lastifil 900 is used for MIG welding of pure nickel and nickel alloys. It is also used for dissimilar joints between nickel, steel and copper and between copper alloys and steel. Lastifil 900 is also used for surfacing steel with nickel and to repair cast-iron castings especially where machinability is required. It has a high corrosion resistance in alkaline environments.

Typical applications:

Chemical industry, food industry, plastic industry, etc. Welding of Ni99,8 – Ni99,6 – Ni99,2 – G-Ni95 and dissimilar joints of nickel to steel and copper. It is used for welding dissimilar materials, such as Nickel 200 and Nickel 201 with: stainless steel, Carbon steel, INCONEL, INCOLOY and MONEL. It is also used to weld MONEL and Cupro-Nickel alloys with Carbon steel, and to weld cupro-nickel alloys with INCONEL and INCOLOY.

Typical chemical composition of all-weld-metal:


Typical mechanical properties of all-weld-metal:

≥380 Mpa≥20 %


Nickel base metal to be cleaned very carefully from all traces of oil and impurities. For root pass: use backing gas.
