PRODUCT

02. Intelligent welding monitoring system

WET-4000SINUT & BOLT Projection

Main Features

  • World’s best system built with quality evaluation function for an individual welded joint performed by intelligent real time welding quality estimation algorithm that starts operating upon the very high precision sampling on welding waveform is made. (Patent registered and commercialized first in the world)

Application

Automobile

System Overview

  • High-speed sampling
  • Signal processing
  • Pattern analysis
  • Individual welded joint quality estimation
  • Output

Benefits

  • System we provide is an innovative intelligent monitoring system providing users with test results indicating “NG” or “GOOD” with accuracy of more than 95% upon completing the welding of the nut and bolt on each individual welded joint, unlike an ordinary case using average values in F/Proof management system, in which the management of the upper and lower limits to the output values of welding process is available but the quality control on each individual welded joint is inadequate.

Applications

  • Nut and bolt projection (M6, M6 and M10), ring projection, cup projection welding, etc.
