【摘要】 本文介绍了大功率电力输送中配套使用的大电流变压器套管中的载流导体——大厚度铝构件的熔化极脉冲氩弧焊接技术。通过选择合适的焊接设备和文中给定的焊接参数,采用特定的施焊方法,可以使焊件整体在无预热的情况下进行焊接,结果表明该焊接方法完全可行有效,可以保证焊接质量和满足使用要求。更多还原

【Abstract】 In this paper,the pulsed MIG welding of large thickness aluminum components which are used as current carrying conductors in high current transformers of high power transmission system,is introduced briefly. With proper welding machines,welding parameters given in this paper and special welding method,we can get high quality welding joints without preheating.From the result,it can be seen that this method is good enough to guarantee the welding quality and satisfy our requirements.更多还原
