Description

B23K covers processes and equipment for joining, modifying, and cutting materials through thermal and energy-based methods, including soldering, unsoldering, welding, cladding, and plating operations. The subclass encompasses both localized heat-cutting techniques (such as flame, plasma, or oxy-fuel cutting) and laser-beam processing for material removal or modification. Specific technologies include manual and automated welding systems, brazing operations, thermal spraying for surface treatment, and precision cutting applications across metal and related materials. This classification excludes general metal-working operations covered elsewhere and focuses specifically on processes that use heat or concentrated energy sources as the primary working mechanism.
