Commodity Codes

• Commodity Codes: UNSPSC 2327 Welding and soldering and brazing machinery and accessories and supplies: Welding, soldering, and brazing are fabrication processes that join materials, usually metals or thermoplastics, by causing coalescence. Welding is often done by melting the workpieces and adding a filler material to form a pool of molten material that cools to become a strong joint, but sometimes pressure is used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which involve melting a lower-melting point material between the workpieces to form a bond. UNSPSC 232714 Welding machinery: Welding machines cover devices used in a wide array of joining processes including arc welding (MIG, TIG, stick, submerged arc), resistance welding, laser welding, electron beam welding, stud welding orbital welding, wave soldering, hot dip brazing, torch brazing, induction brazing, ultrasonic and friction welding. Welding machines include complete devices as well as their power sources, monitors, and controllers. UNSPSC 232717 Welding and soldering and brazing accessories: Accessories for welding, soldering, and brazing machinery and/or equipment used during the welding, soldering, or brazing operations. UNSPSC 232718 Welding and soldering and brazing supplies: Materials used during welding, soldering, and brazing processes that are consumable or can be used up. UNSPSC 232819 Metal cleaning machinery and supplies: Machinery used for removal of solid, semisolid, or liquid contaminants from a surface. This is essential for more effective application of metalworking fluids, coating and painting, adhesive bonding, welding, brazing, soldering, reliable functioning of manufactured parts in machinery, food and beverage containers, storage, and assembly options. UNSPSC 401742 Pipe sockolets: A fitting used for socket welding branch connection, which requires a reinforcing pad. UNSPSC 401751 Pipe weldolets: A fitting used for butt weld branch connection where standard tee is not available due to size restrictions available and the piping is of critical / high pressure service. UNSPSC 731819 Welding and brazing and soldering services UNSPSC 15121805 Anti weld pastes UNSPSC 20121324 Sand control ring: A component used to seal by welding the filter and outside cover of a sand control device. UNSPSC 23151603 Fusion welding or glass drawing machines UNSPSC 23153204 Welding robots UNSPSC 23241401 Bench grinder: Depending on the grade of the grinding wheel it may be used for sharpening cutting tools such as lathe tools or drill bits. Alternatively it may be used to roughly shape metal prior to welding or fitting. UNSPSC 23271401 Submerged arc welding machine: A submerged arc-welding machine creates a thick layer of flux completely covers the molten metal and prevents spatter and sparks. The flux also acts as a thermal insulator, allowing deep penetration of heat into the workpiece. UNSPSC 23271402 Ultrasonic welding machine: Ultrasonic welding machinery joins the contacting surfaces of two pieces by subjecting them to a static normal force and oscillating shearing (tangential) stresses. It can be used with a wide variety of metallic and nonmetallic materials, including dissimilar metals and is extensively used for joining plastics. UNSPSC 23271403 Projection welding machine: One or more projections (dimples) are embossed, forged, or machined on one of the surfaces to be welded. The two pieces are then pressed together and weld nuggets are formed as the projections are compressed. UNSPSC 23271404 Plasma arc welding machine: Plasma-arc welding machines use a concentrated stream of plasma, and ionized hot gas, composed of nearly equal numbers of electrons and ions. Plasma-arc welds create deeper and narrower welds on a variety of metals. UNSPSC 23271405 Laser welding machine: Laser beam welding utilizes a high-power laser beam as the source of heat to produce a fusion weld. UNSPSC 23271406 Spot welding machine: Spot welding is the most common form of resistance welding. Spot welding is usually used on sheet metal and in applications having some type of overlapping joint design. Resistance spot welds are made from electrodes on both sides of the joint and no filler metal is used. UNSPSC 23271407 Tungsten inert gas welding machine: The TIG process lets one weld thinner material than other processes and it also provides excellent fusion. TIG also produces the best looking weld beads, which are used when cosmetic appearances are important.

UNSPSC 23271409 Shielded metal arc welding or stick welding machine: Stick, the most basic of welding processes, offers the easiest option for joining steel and other metals.

The heat penetrates deeply, making it possible to weld much thicker workpieces than is possible with most other welding processes. However, because the electron beam is tightly focused, the total heat input is actually much lower than that of any arc welding process. UNSPSC 23271414 Electro slag welding ESW machine: A type of welding machine employing a single pass welding process for thick --greater than 25mm up to about 300mm--materials in a vertical or close to vertical position. Welding is made by melting the basic material and wire by the heat of the current flowing into the slag. UNSPSC 23271415 Cold pressure or contact welding machine: A type of welding machine in which joining takes place without fusion at the interface of the two parts to be welded. Unlike in the fusion-welding processes, no liquid or molten phase is present in the joint. Pressure is applied to the workpieces through dies or rolls thus producing adhesion. UNSPSC 23271416 Friction welding FW machine: A welding machine that employs a solid-state welding process that generates heat through mechanical friction between a moving workpiece and a stationary component. Because no melt occurs, friction welding is not actually a welding process in the traditional sense, but a forging technique.
