Intelligentized Methodology for Arc Welding
Saturday, April 24, 2010
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-
