hitsaus
Hitsaus (welding) is a fabrication process that joins materials—typically metals—by heating them to fusion, or by applying pressure, often with filler material. Unlike soldering or brazing, welding fuses the base materials at the joint, creating a single, continuous structure.
Common methods fall into several families: arc welding (SMAW, GMAW/MIG, GTAW/TIG, FCAW), resistance welding (spot, seam),
Welded materials are mainly ferrous and non-ferrous metals, such as steel and aluminum alloys; some plastics
Safety and quality are central concerns: welding generates heat, bright UV light, fumes, and radiation, requiring
Welding supports construction, shipbuilding, automotive, aerospace, and manufacturing. The field has evolved with automation, robotics, and
