High Performance Welding Wire ERNi-1 Matching Nickel Base Alloy Welding Wire

Production Description

The nominal composition (wt%) of ERNi-1 weld metal is 96Ni, 3Ti. This filler metal is used for welding commercial pure nickel (according to ASTM standards B160, B161, B162 and B163, UNS N02200 and N02201) forgings and castings by gas tungsten arc welding, gas metal arc welding, submerged arc welding and plasma welding. When using these welding methods, the filler metal contains enough Ti to control the porosity in the weld metal.

ERNi-1 weld metal is used for nickel 200/201 welding, has corrosion resistance, and is suitable for a variety of welding methods and dissimilar joints. It is suitable for trays, baskets and fixtures, etc., with various welding positions, and the shielding gas is MIG75%Ar/25%He or TIG100%Ar.

Characteristic

For welding of nickel 200 or 201.

Also used for overlaying of steel and repairing cast iron castings.

It can also be used for dissimilar joints between nickel or nickel alloys and stainless or ferritic steels.

Has good corrosion resistance, especially in alkalis

Preparation process

The preparation process of ERNiCu-7 welding wire usually includes the following steps:

Raw material preparation: Select high-quality metal raw materials to ensure that their chemical composition and physical properties meet the requirements.

Alloy smelting: Put the raw materials into the arc melting furnace for smelting, control the smelting temperature and atmosphere, and ensure that the alloy composition is uniform.

Wire drawing: The smelted alloy liquid is drawn into welding wire of the required diameter through a wire drawing machine.

Surface treatment: Clean and treat the surface of the welding wire to remove oxides and impurities and improve welding quality.

Optimization of the preparation process can improve the quality and performance of the welding wire, reduce production costs, and improve production efficiency.
