氙气闪光灯灯电极对焊工艺研究
|
摘要
随着人们对拍照质量的要求不断提高,氙气闪光灯的核心部件——电极的尺寸也更趋向精细。传统的焊接方式难以达到新的要求,故研究氙气闪光灯电极对焊工艺有着现实意义。将传统的横向对焊改成竖向对焊;改进镍丝切刀的设计,提高切口端面质量;并将传统的酒精保护方式改为氢氮混合气体保护。结果表明,新的对焊工艺在焊接结子外观质量、焊接牢度、金相组织等方面都有了显著的改进。
With the improvement of product quality requirement, the dimension of the core part of xenon flash-electrode is getting more precise. Traditional way of welding is hard to meet the new requirement, so the research of electrode butt welding has realistic meaning.The experiments changed welding direction from horizontal to vertical, redesigned the blade for cutting nickel wire, improved the quality of cutting edge, and the protection gas was changed from alcohol to mixing gas of hydrogen nitrogen. The results show that the quality of welding knot, weld strength and metallurgical structure are improved by new butt welding process.
