1、本科畢業(yè)論文（設(shè)計）題 目：45 鋼_機器人自動焊接的工藝研究 學(xué)生姓名： XXXX 學(xué) 號： XXXXXXXX 系 別： 機電及自動化工程系 年 級： 2008 專 業(yè)： 機械設(shè)計制造及其自動化 指導(dǎo)老師： 陳丙

2、三 職 稱： 講師 完成日期： 2012 年 6 月 IIAbstractWelding is a poor labor conditions, dust, heat radiation, high risk work, using the robot using artificial brings big. Can

3、greatly improve the automation level of production equipment, improve labor productivity thereby. Industrial robot 's appearance makes people first thought of using it to replace the manual welding, reduce the labor

4、intensity of welders, therefore, study of robot welding technology has profound theoretical significance and practical value.This article from the robot automatic welding process of angle, the“45steel robot automatic wel

5、ding“ technology was studied. Through access to relevant information, understand the robot automatic welding and CO2 welding principle. Analysis of 45steel by CO2gas shielded welding process, determine the welding parame

6、ters, such as welding current selection of 200,210,230,250( A ), selected according to the welding parameter, formulate the table of orthogonal experiment and experiment. Through the visual analysis method to deal with t

7、he experiment results, the primary and secondary factors in order of welding current, welding voltage, welding groove, welding speed, wire type. At the same time that the optimal scheme, the optimal scheme and orthogonal

8、 experiment the best method in Experiment four were compared, in order to verify the optimal scheme is optimal, by metal magnetic memory testing experiment, to detect the damage and stress concentration in weld, analyzes
