โ๏ธ Patent Watch: Smarter Welding for Transmission Towers
Qingdao Wuxiao Group just secured a new utility model patent (authorized October 9, 2026) for a node auxiliary welding device that tackles one of the trickiest jobs in tower fabrication: variable-slope angle steel welding.
What makes it stand out:
๐น Fixed auxiliary plates paired with angle-adjusting plates handle joints at different slopes
๐น Radially arranged welding positioning rods guide precise node welding across varied angles and apertures
๐น One device covers multi-specification angle steel towers โ a much wider working range than traditional fixtures
๐น Faster setup and more consistent weld quality for lattice tower assembly lines
As power grids expand, demand keeps climbing for transmission towers built quickly and weld-tested for strength. Tooling innovations like this cut repositioning time and help fabricators deliver uniform joints batch after batch.
What do you think โ will adaptive fixtures like this become standard in tower shops? Drop your take below ๐
