Welding machines and apparatus; for resistance welding of metal, fully or partly automatic, whether or not capable of cutting

HS v2017 Code: 851521

About welding machines and apparatus; for resistance welding of metal, fully or partly automatic, whether or not capable of cutting

hs code 851521 covers a critical component of the metalworking industry - welding machines and apparatus for resistance welding of metal. These specialized machines play a vital role in the fabrication and assembly of a wide range of metal products, from automotive parts to industrial equipment. The global demand for these welding machines is driven by the continued growth of manufacturing sectors, particularly in emerging economies, as well as the need for efficient and automated welding solutions to improve productivity and quality.

Production process

Welding machines classified under hs code 851521 utilize resistance welding techniques, where the heat required for welding is generated by the electrical resistance of the metal parts being joined. These machines can be fully or partly automated, allowing for precise control over the welding process and increased efficiency. The key production steps involve clamping the metal parts in place, applying an electrical current to heat the contact points, and then applying pressure to fuse the parts together.

Production inputs

The primary inputs for the production of hs code 851521 welding machines include various metal components, such as frames, electrodes, and control systems, as well as electrical and electronic components like transformers, switches, and sensors. Manufacturers also rely on specialized software and programming to enable the automated and semi-automated functionality of these machines. Additionally, the production process requires access to skilled labor, including engineers, technicians, and assembly workers.

Production outputs

Welding machines classified under hs code 851521 are primarily used in the manufacturing of metal products, such as 871600 Machinery, plant and laboratory equipment, 870000 Vehicles other than railway or tramway rolling-stock, and parts and accessories thereof, and 940000 Furniture; bedding, mattresses, mattress supports, cushions and similar stuffed furnishings; lamps and lighting fittings, not elsewhere specified or included; illuminated signs, illuminated name-plates and the like; prefabricated buildings. These welding machines enable the efficient and precise joining of metal components, which is essential for the production of a wide range of industrial and consumer goods.
