Strand Annealing
Inert gas strand annealing furnace is equipped with take-up spoolers and coilers for annealing temperatures up to 3000 degrees Fahrenheit.

Specifications
Rolled Alloys supplies weld wire to meet requirements of AMS, MIL, AWS, and many aerospace companies. Most weld filler is covered by AWS, the American Welding Society, specifications. The Aerospace welding wires are usually purchased to an AMS spec, whether or not they also have AWS.

  • AMS
  • AWS
  • Pratt & Whitney Laboratory Control at Source (LCS) Approved – Reference PWA Appendix 36
  • GE S400/S1000
  • MSRR

Flag Tagging
Flag tagging is a positive method of identification. The tag has a pressure sensitive adhesive backing and is placed approximately 1.2 inch from end of the rod. Tags are printed with alloy and AMS specifications for identification.

Centerless Grinding
Centerless grinding is used for surface finishing of straight material. This includes through feed grinding of various materials for Screw Machine, Electronics, Automotive, and Medical.Our size range is 0.020 to 0.200 inches in diameter.

WireCleaning
Rolled Alloys provides superior quality cleanliness of all wire products tested to the Kodak gray scale.

Custom Packaging
We have custom packaging to meet customer requirements or specifications. We do standard packaging to protect the products we manufacture.

Welding Processes


Dissimilar Welding
Selecting the best weld filler for a dissimilar weld should obtain similar corrosion resistance and mechanical properties of the higher alloy. When welding two different alloys to each other, the choice of filler metal is normally determined by the more highly alloyed of the two parent metals. For example, when welding 304L to 316L, a 316L filler should be used. In other cases, it is also important to select a filler metal that also increases the ease of welding. For example, when welding 310 stainless to a casting, RA330® weld filler is used because of its high temperature strength, oxidation resistance as well as maintaining ductility in the weld and avoiding hot cracking. The weld wire selection guide above is a good place to start when selecting the proper filler metal.

When welding stainless steel to low-alloy steels, it is generally advisable to reduce weld dilution as much as possible. Heat input must be limited The interpass temperature must not exceed 150°C.

Similar Welding
When welding two identical alloys, the choice of filler metal is generally determined by the base metal. To ensure the weld will have optimum mechanical and corrosion performance, the chemistry of the filler metal must be related to the alloy being welded. Often, the filler metal chemistry will be slightly higher in alloy content than the base metal. For example, higher levels in Cr, Ni, Mo, and Mn are common in weld fillers. This overalloying helps compensate for losses in arc and alloy segregation of alloying elements when the weld is cooling.

Welding MIG MIG (Metal Inert Gas), now known as GMAW (Gas Metal Arc Welding). This is always done with spooled wire, usually 0.035” or 0.045” (0.89 or 1.14mm), rarely 0.62” (1.57mm). We sell 25-30# spools (11-14kg), other weights are made. The majority of our welding product sales are GMAW.

TIG Wire TIG (Tungsten Inert Gas) is now known as GTAW (Gas Tungsten Arc Weld). Originally it was called Heliarc, and still is, by some people. GTAW is usually done with 36” straight lengths of bare wire. Automatic TIG (GTAW) machines use spooled wire just like GMAW (MIG). But 36” lengths of wire are only used for TIG/GTAW.

SMAW Wire SMAW (Shielded Metal Arc Weld) commonly called “stick welding”, or Manual Arc Welding, or welding with covered electrodes. These covered electrodes are typically 14” (360mm) lengths of wire, coated with a gray flux all but the last 1½ to 2” (40—50mm). In appearance they are not unlike large 4th of July sparklers. Extra alloying elements are often added in with the flux coating, so core wire chemistry may be quite different from the final deposited weld bead.

Weld Wire PAW (Plasma Arc Weld) similar to GTAW/TIG but much hotter and finer, more narrow, arc. At Rolled Alloys we use the plasma arc to cut plate, but it is also an excellent welding process. A small amount of 36” length filler wire is used when plasma arc welding.

Welding SAW SAW (Submerged Arc Weld) is an automatic process using spooled wire like GMAW/MIG, except the wire is larger diameter. 3/32” (2.4mm) dia is common for nickel alloys, but 1/16” (1.6mm) and 1/8” (3.2mm) diameter wires are also used. Instead of shielding the welding arc with the inert gas argon, in SAW a hopper drops granulated flux (like coarse sand) down, to melt in the arc and protect the weld puddle from oxidation. For every pound (kilo) of weld wire used, SAW consumes about a pound (kilo) of flux as well.

SAW is a high heat input, high production process best suited for large carbon steel fabrication. It is used on stainless as well. In recent years, tens of thousands of pounds of the nickel alloys RA330® & AL-6XN® have successfully been submerged arc welded.

Welding FCAW FCAW Flux cored arc welding. Also spooled wire, looks the same as MIG/GMAW wire, but flux cored wire is really a hollow metal tube, with powdered flux and some alloying elements in the tube. It is available in various stainless grades, and less commonly in nickel alloys (82 and 625 are available). We also sell flux cored 2209 for welding 2205 duplex.
