Our Welding Process for Automation and Higher Efficiency

Our Line-ups for Welding Automation Technology by Stage

Integrated technolgy of welding consumables, welding system and welding process enables welding automation at every stage.

Our Line-ups for Welding Automation Technology by Stage

Large Assembly Welding System

  • Automatic vertical upward and horizontal fillet welding within the confined space of ship hull block made possible by a miniature ARCMAN™ robot mounted on a robot carry.
  • By integrating the data from 3D models with our automatic programming soft "SMART TEACHNG™", manual programming is not required. SMART TEACHING™ can establish program at around 3minitues for about 400 welding joints od the ship hull block
  • 30% improvement in welding speed in vertical upward welding over connventional all-positional welding wire whilist keeping the weldability of horizontal fillet welding using FAMILIARC™ DW-100R special FCAW and new control features.
