A "German type hose clamp with welding machine" refers to specialized automated machinery used to mass-produce high-quality, worm-drive hose clamps, known for their smooth bands and high clamping force, often using integrated spot or laser welding for connecting the band ends, with machines featuring PLC controls for efficiency in producing stainless steel or other material clamps for automotive and industrial uses. 

In essence, it's a sophisticated factory machine making high-performance German-style clamps automatically, using welding as a key assembly step.
