〔本刊讯〕由机械委成都电焊机研究所于1988年3月22～23日在成都主持召开了由成都电焊机厂研制的UYZ—80型单相次级整流闪光对焊机(以下简称焊机)的委级鉴定会。参加会议的有13个单位、38名代表。焊机是在变压器次级用组合二极管进行单相全波整流为直流电流对工件加热焊接的新型焊机。具有在焊接同样截面的工件时,所需的输入功率比交流焊机要少、焊接质量好、功率因素高等优点。焊机的次级经整流后还并联大容量的电容器,改善波纹系数,提高了闪光的稳定性、闪尤颗粒细微,改善了焊接质量。焊机对炭钢、铝、铝—铜对焊进行了工艺
[News] The Chengdu Machinery Welding Commission Institute of Welding March 22, 1988 to 23 in Chengdu hosted by the Chengdu Welding Factory developed UYZ-80-type single-phase secondary flash flash welding machine (hereinafter referred to as Welder) Commission appraisal meeting. There are 13 units and 38 delegates attending the meeting. The welding machine is a new type of welding machine that heats and solves workpieces by single-phase full-wave rectification with a combination diode in the transformer secondary. With the welding of the same cross-section of the workpiece, the required input power less than the AC welder, welding quality, high power factor advantages. Welder secondary after rectification but also large-capacity capacitors in parallel to improve the ripple factor to improve the stability of the flash, especially flash particles, improved welding quality. Welder carbon steel, aluminum, aluminum - copper butt welding process
