Intelligentized Methodology for Arc Welding

Abstract 

In this chapter,an introductionis given on the development of welding handicraft,manufacturing technology and key technologies of welding automation and intelligentization. Recent twenty years have seen great development of welding

robot in modern manufacturing industry,where arc welding is one of the main stream technology.A large number of researches show that automatic control of the welding process requires not only good performance of the equipment,but also technologies,namely sensing,modeling and controlling of the welding process.None of the technologiesis neglectable for welding process control,in which sensing is to monitor thep rocess and extract characteristic information of the welding process modeling is to identify thep rocess based on acquired information;and controlling is to regulate the welding process based on the established models.The main partin controllingistodesigncontrollerformulti-variablescoupled,nonlinearandtime-

Robotic Welding Intelligence and Automation

Abstract.

For modern transport systems Aluminumis getting of growing importance.To fully utilize this potential economic,effective and stable joining technologies have to be available.However, the special features of Aluminium materials like high heat conductivity,oxide formation,pore and hot cracking susceptibility require special measures for high quality welding especially for thin sheet metals.New developments in gas metal arc welding power sources, torches and wire feeders for Aluminum welding to overcome these problems will be described.Besides the technological factors system aspects and their influencean process stability and manufacturing up-time will also bediscussed.Actual and potential future applications of these new developments will be demonstrated.
