Cross Wire Welding
Cross wire welding is used in many everyday applications. It is perhaps the most common nonautomotive application for resistance welding. There are many everyday uses for products made with cross wire welding, including shopping carts, toaster guides, wire meshes for reinforcing concrete, fences, and jail bars. In fact, our world would be unrecognizable without the reinforcing meshes used in buildings, roads, tunnels, and prefabricated components.
NSRW is a metal service center, specializing in copper alloys. We have an extensive full line inventory of components and raw material for the Welded Wire Reinforcement / Cross Wire Welding Industry. If what you need is not off the shelf, here at NSRW we have an in house machine shop that can accommodate your welding needs.
Applications where Wire Mesh Welding / Cross Wire Welding can be found in:
- Concrete reinforcement
- Wire grate
- Display articles
- Animal cages
- Supermarket carts
- Cable ducts
- Garden fencing
Materials Used for Cross Wire Welding
Beryllium Copper (17510) Class 3
Class 3 Alloy is specifically recommended for projection welding dies, flash and butt welding dies, current carrying shafts and bushings. As castings, Class 3 Alloy (having higher strength than Class 2), is recommended for highly stressed welder structural current carrying members and heavy duty offset electrode holders.
Class 3 Alloy is generally recommended for spot welding and seam welding steels having high electrical resistance, such as stainless steels. The Class 3 Alloy is heat treatable.
Beryllium Free Copper (18000) Class 3
Beryllium Free Copper (18000) meets the mechanical requirements of RWMA Class 3 Copper. C18000 is utilized when a combination of very good mechanical strength along with moderate electrical and thermal electrical conductivity are required. C18000 is a viable substitute for C17500 and C17510 for many applications. C18000 is a heat treatable copper alloy.
Tungsten 100W is extremely hard and its ductility is relatively low. It cannot be machined but may be ground to the required shape. It does not alloy appreciably with nonferrous materials and is used for cross wire welding of metals such as copper and brass. It is also used for electro brazing electrode material and for some electrical upsetting operations.
Molybdenum 100M is used principally for electro brazing electrode material and for cross wire welding of nonferrous metals. It is not as hard as Tungsten 100W material and may be machined or drilled to fit the parts to be joined. A typical application of this material, as an electrode, is the welding or brazing of braided or solid copper conductors to ferrous or nonferrous terminals, lugs or fittings.
Copper Tungsten 30W3 and Tungsten Carbide TC10
Copper Tungsten 30W3 and Tungsten Carbide TC10 alloys are recommended for volume projection welding dies where the pressures involved are relatively high. Electrical upsetting of nonferrous metals and low carbon steel is usually accomplished by the use of such Copper Tungsten materials as die facings. Cross wire welding of large, diameter wire and rod is accomplished with such Copper Tungsten materials.
