HS v2022 Code: 851531

About welding machines and apparatus; for arc (including plasma arc) welding of metals, fully or partly automatic, whether or not capable of cutting

HS code 851531 covers a crucial segment of the metal fabrication industry, encompassing welding machines and apparatus used for arc (including plasma arc) welding of metals. These automated or semi-automated welding systems play a vital role in the production of a wide range of metal-based products, from industrial machinery to consumer goods, making them an integral part of the broader manufacturing ecosystem.

Production process

The primary production technique for the equipment described under HS code 851531 is the arc welding process, which utilizes an electric arc to fuse metal components together. This can be done in a fully automated or semi-automated manner, with the welding machine controlling the arc, feed rate, and other parameters to ensure consistent, high-quality welds. Some models may also incorporate plasma arc welding technology, which uses a constricted arc to produce a high-energy, high-temperature plasma jet for enhanced welding performance.

Production inputs

The key inputs for the production of welding machines and apparatus under HS code 851531 include various metal components, such as steel frames, electrical motors, control systems, and welding consumables like electrodes and shielding gases. Manufacturers also rely on specialized manufacturing equipment, such as CNC machining centers and assembly lines, to fabricate and assemble these welding systems. Additionally, research and development efforts, as well as skilled engineering and technical personnel, are essential inputs for the continuous innovation and improvement of these welding solutions.

Production outputs

The primary output of the industry covered by HS code 851531 is the welding machines and apparatus themselves, which are then consumed by a wide range of manufacturing and fabrication industries. These welding systems may be used in the production of 731320 (Stoves, ranges, grates, cookers (including those with subsidiary boilers for central heating), barbecues, braziers, gas-rings, plate warmers and similar non-electric domestic appliances, and parts thereof, of iron or steel), 842139 Filtering or purifying machinery and apparatus for gases, n.e.s., and 848180 Taps, cocks, valves and similar appliances for pipes, boiler shells, tanks, vats or the like, including pressure-reducing valves and thermostatically controlled valves, among other metal-based products.
