Innovative Robotic System for MAG Welding with Two Filler Metal Wire Feeders

Abstract

The article describes an innovative robotic MAG method for the welding for ship elements. The method involves the use of two wire feeders and one torch, making it possible to weld two different steel grades. In addition, the robot application is equipped with an off-line programming DTPS system (Desk Top Programming & Simulation System) as well as an arc sensor, a gas nozzle touch sensor and a laser touch sensor featuring a seam finding function. The system is also provided with a welding parameter monitoring and archiving system.
