Copper Nickel Welding Guide - Shihang

Copper-Nickel alloys have been around for 50 years and were originally used in offshore pipework. Over time their application has been expanded to include parts in sea ships, specifically in condenser/heat exchangers on ships and are used in desalination, power plants and offshore fire water systems, and for the sheathed splash zone protection of oil and gas platform legs.

International Standards and professional advice should be sought for specific designs. Copper-nickel Welding and FabricationThere are two main grades of copper-nickel alloy used in marine service - 90-10 (10% nickel) and 70-30 (30% nickel). The 70-30 alloy is stronger and has greater resistance to seawater flow; but 90-10 will provide good service for most applications and, being less expensive, tends to be more widely used. Both alloys contain small but important

Copper-nickel Welding and Fabrication

When it is possible to weld from either side on plates 12mm and thicker, the usual procedure is to weld the steel side first with a steel filler metal. The alloy side is prepared for welding by back-gouging to sound metal and welded with a first pass of 65% nickel-copper alloy followed by 70-30 copper-nickel. EN 1011-1:2009 - Welding - Recommendations for welding EN 1011-1:2009 - This European Standard contains general guidance for the arc welding of metallic materials in all forms of product (e.g. cast, wrought, extruded, forged). The processes and techniques referred to in this Part of EN 1011 may not all be relevant to all materials. Additional information relevant to specific materials is given in the relevant Parts of the Standard. Guide for the Fusion Welding ofium and The standard Guide for the Fusion Welding of ium and ium Alloys provides instructional guidance for the welding of titanium and titanium alloys.

Nickel and High Nickel Alloys Welding and Metallurgy

Nickel alloy 201 is a low carbon grade of alloy 200. Nickel 200 is subjected to the production of a grain boundary graphite phase that decreases ductility extensively. Resulting Nickel alloy 200 offers maximum temperature service up to 600oF or 315oC. However alloy 201 is utilized in the applications above this temperature limit. Nickel and you - HSEthe welding of nickel and alloys and when using welding rods containing nickel; However, general short-term effects can . include:Nickel and you. Working with nickel are you at risk? Health and Safety Executive. This guidance is issued by the Health and Safety Executive. Following the guidance SAFETY INFORMATION SHEET FOR NICKEL ALLOYGuidance on the welding of metals and alloys is provided on the European Welding Association website (4). The guidance document will provide background information on health hazards posed by welding processes and appropriate risk management measures. 4.3 First Aid Measures There are no specific First Aid Measures developed for the nickel alloy.

*Nickel alloy products as provided contain chromium metal in the zero valence state. As such, chromium metal does not present an unusual health hazard. However, operations such as burning, welding, sawing, brazing or grinding may generate airborne concentrations of hexavalent chromium.

The nickel alloys (Alloy 600, for example) have even lower rates of expansion. In general, welding without filler metal should be avoided. In the case of one lean duplex stainless with about 1.5 percent nickel, the filler metal has about 6-7 percent more nickel to ensure suitable properties in the weld.

These exceptions are:The nickel alloys will acquire a surface oxide coating which melts at a temperature approximately 538 o C above the meting point of the base metal.

Welding of Nickel Alloys

Nickel alloys can be joined reliably by all types of welding processes or methods, with the exception of forge welding and oxyacetylene welding. The most widely employed processes for welding the non-age-hardenable (solid-solution-strengthened) wrought nickel alloys are gas-tungsten arc welding (GTAW), gas-metal arc welding (GMAW), and shielded metal arc welding (SMAW).
