Documentation, Monitoring, Fault detection
WeldQAS is an automatic welding monitoring system. By monitoring welding parameters during the welding process, immediate error response is possible, averting consequential damage.

WeldQAS acquires real-time data from welding production, reveals inefficiencies and enables action to optimise the production process.

Add to shopping list


  • Records welding parameters such as welding current, welding voltage, gas flow rate, wire feed speed during the welding process online without an additional accessory added on the welding torch
  • Based on a new technology of recording high-resolution digital data and intelligent data processing in a signal processor
  • Using patented algorithms and welding parameters, WeldQAS allows detection of pores, burn-through, wire defects (MSG) and other welding irregularities
  • Data are stored in databases and provide an overview for optimising and stabilising the welding production. WeldQAS is network compatible and the data are automatically stored on a central server
  • The WeldQAS series consist of a compact version and a cabinet version to which sensors can be connected to record process variables. Process variables can also be recorded using industrial fieldbus systems or power source-specific buses

Welding Process

  • GTAW (TIG - Tungsten Inert Gas )
  • GMAW (MIG/MAG - Metal Inert Gas / Metal Active Gas)
  • SAW - Submerged Arc Welding
