Arc Welding and Soldering Alloys

Arc spray, commonly called twin wire arc spraying, is a coating process in which an electric arc melts and atomizes metal feedstock before propelling onto a substrate to form dense, solid, and durable coatings. Browse the Best info about k94600.

For this application to work successfully, the wire must have tight compositional tolerances and be spooled correctly for consistent performance. In addition, its surface finish must be of superior quality.

Wires for Arc Spraying

Arc spraying is an efficient method for coating metallic substrates with coatings composed of pure or mixed metal alloys, such as machine components, bearing journals, and shafts with pure or mixed metal alloy wires melted by electricity into droplets of liquid metal alloy that are then deposited onto them using compressed air spraying technology. Arc spraying requires less power inputs than other thermal spraying techniques while providing higher deposition rates for coating thickness and material transfer. It has become an integral component in industrial maintenance practices. It is trendy for repairing machine components bearing journals and shafts, which utilize pure or mixed metal alloy wire melt to reconstruct industrial equipment, including machine components, taking journals and posts using compressed air spray technology – using electricity to melt pure metal alloy wires before spraying it onto workpieces using compact air compressed air rushing technology allowing high deposition rates for both coating thickness and material transfer rates than traditional thermal spraying techniques allowing high deposition rates both thickness deposition rates and material transfer.

Arc spraying is a highly portable process and can be done on-site or in the shop, making it the ideal solution for large or difficult-to-reach surfaces like pipe seams, piston rings, capacitors, boiler walls, and other extensive infrastructure. This process can also repair corrosion damage to metallic surfaces and wear from corrosion and wear – which makes it especially suitable for applications found within paper mills, boilers, petroleum, or chemical industries where hardening needs to be high.

Silicon aluminum, MSSA Spraybronze, and Tufton 500 are among the most frequently used arc spraying alloys for hard facing, as these materials feature wide particle sizes to resist atmospheric and chemical corrosion and galling and abrasion. Furthermore, cored wire technology provides for custom mixtures that cannot be drawn as solid wire and thus allows more versatile applications when repairing or rebuilding machines and structures. All arc spray alloys produced meet stringent compositional tolerances on precision wound spools.

Silicon Aluminium

Silicon is an essential aluminum alloying element, improving fluidity, casting characteristics, and flexibility while decreasing hot cracking risk in restrained castings. Binary aluminum-silicon alloys tend to have relatively low strengths; grain refiners like boron, titanium, and strontium may be added for increased strength and flexibility.

Alloys with up to 12% silicon content are known as hypoeutectic alloys and feature aluminum dendrites as the dominant shape. When the silicon content exceeds this threshold, however, the cast alloy develops a hypereutectic microstructure with primary aluminum and secondary eutectic structures; this form of casting is often employed when casting large and heavy components such as engine blocks, gears, and transmission cases.

The creep resistance of these alloys is low; however, silicon does not significantly diminish it. They may be improved through heat treatment and by adding iron, nickel, manganese, magnesium, chromium, or zinc, increasing fatigue strength.

Machinability is generally poor; however, additions of phosphorus that improve the distribution of silicon and sodium alloying slightly improve it. Alloys are susceptible to thermal fatigue caused by complex loads that reduce fatigue strength.

California Fine Wire offers various aluminum alloys with silicon, such as AlSi1 wire (99% aluminum and 1% silicon), commonly called silumin. California Fine Wire also offers wedge bonding wire. Wedge bonding is a fast and cost-effective method of creating aluminum-silicon arc welding wire using conventional equipment, where an aluminum arc heats the wire until its melting point before rapidly cooling it back in the air, creating a substantial and long-term bond that makes California Fine Wire perfect for electronic components and automotive parts production.

MSSA Spraybronze

MSSA provides an array of bronze welding and soldering alloys in all forms to repair and protect equipment in harsh environments. These include complex soldering/brazing processes, which use lower melting point alloys like gold, silver, or copper base, while soft soldering employs low melting point tin/lead solders; soft soldering uses lower melting point tin/lead solders from MSSA Interweld’s Tin/Bronze Wire is precision machined for use across Mig/Tig applications as well as various welding applications such as Mig/Tig.

MSSA provides metal spray supplies for standard flame spray and arc spray equipment in multiple diameters, paying close attention to surface treatment and tolerance. In addition, they also produce advanced cored welding and spraying wires to suit unique applications such as high-pressure/high-temperature applications, wear-resistant properties, and anti-corrosion features.

MSSA flame spray systems can also be enhanced with accessories and consumables to optimize performance, such as deflected flame spray extensions, which allow for hard-to-reach areas to be reached by spraying. These extenders attach directly to an arc spray pistol in sizes of 150mm, 300mm, or 450mm variants.

MSSA’s ARC 528 Pistol is a heavy-duty, high-performance arc spray gun designed for spraying all standard wire sizes up to 4.76mm using only one fuel gas source (acetylene). With outstanding control and consistency for hard-facing applications with faster deposition rates than manual pistols.

Tufton 500

Marshall Tufton Portable Bluetooth Speaker offers an immersive music experience for parties, barbecues, and picnics. Its guitar-inspired carry strap for effortless traveling on adventures and a visual indicator on top of the speaker to monitor battery status make it a perfect companion.

This invention describes a composite thermal spray wire comprised of a stainless steel sheath surrounding a titanium diboride core made up of metallic or non-metallic powders and coated with an arc spraying process using an arc gun to cover objects such as vehicles or buildings with coatings utilizing various compositions such as tin or graphite as needed for each application. Furthermore, additives to promote austenite formation, ferritization or martensite formation, and mechanical strength may be added for optimal use as part of each application process.

The experiments performed with this invention’s wires demonstrate superior abrasion resistance compared with solid pieces or other arc-sprayed stainless steel-based coatings and excellent corrosion resistance for their sheaths. Performance can be enhanced further by selecting an optimal powder mixture and core, for instance, by altering purity levels of titanium diboride powder particle sizes or coarsening its particle size; coarse stainless steel powder has better mechanical properties than its finer counterpart; Table II shows results of experiments performed using these wires; variations between test results are due to various types of cores and additives used during each case compared with each experiment performed – these differences between test results is due to core types used, powder mixture combinations used and additive combinations used.


MSSA offers hard-surfaced solutions to combat corrosion and wear in the oil and gas industry with our spray equipment, such as thermal-sprayed aluminum-zinc (TSZ) coatings as well as arc-sprayed stainless steel/Stellite cobalt-chromium alloy coatings for critical components like flare booms and shafts.

The arc spray process utilizes an electric arc to melt metal wires, which are then atomized by compressed air into a spray stream to protect and repair surfaces. These tough yet durable coatings offer exceptional resistance against impact damage, abrasion, and corrosion.

Flamespray stands out as an industry spray technique by being extremely versatile; it can be used to apply powdered and solid materials and wires. This makes a helpful flame spray when traditional powder or plasma sprays are not used or fast application time is needed.
