我厂引进法国MG公司FA4系列高压开关,它的外壳是以铝代铁,由于铝的焊接在我厂仅刚开始,特别对于中厚板14mm～60mm板的焊接,又缺乏自动与半自动氩弧焊机。我们根据工厂现有设备,利用二台手工钨极氩弧焊机,创造了一种新的铝焊接方法,即“不开坡口的双人双面焊接法”。适用于6mm～16mm铝及铝合金的立焊。此法用于圆罐的环缝焊接,也适用球罐的制造。本文主要叙述LF_(11)铝合金板双人立焊工艺。
I plant the introduction of French MG FA4 series high-voltage switchgear, and its shell is based on aluminum, aluminum welding in our factory has just begun, especially for plate 14mm ~ 60mm plate welding, and the lack of automatic and semi-automatic argon arc welder. We have created a new aluminum welding method using two hand-held TIG welders based on the existing equipment in the factory, namely the “double-sided double-sided welding without groove”. Suitable for vertical welding of 6mm ~ 16mm aluminum and aluminum alloy. This method is used for circular seam welding round cans, but also for the manufacture of spherical cans. This article mainly describes the LF_ (11) aluminum alloy plate welding process.
