我厂生产的δ=14、16、18毫米纯铝中厚板容器,由于铝板比较厚,用一般的手工氩弧焊机焊接有困难,必须使用熔化极自动氩弧焊机。为此,我们将现有的 EA—1000启动焊机改装成自动氩弧焊机。主要改装了下列几点: 1.增设了一套熔化极氩弧焊焊枪; 2.将送丝电机与送丝压轮之间的传动比,由原来的16O:1改为96:1; 3.改变原有的锯齿形送丝压轮外径形状,左压轮改为60°V形槽,右压轮滚花不开槽;
I produced δ = 14,16,18 mm pure aluminum plate container, due to the relatively thick aluminum plate, with a general manual welding machine welding difficulties, you must use the melting electrode automatic welding machine. For this purpose, we retrofit the existing EA-1000 start-up welder into an automatic TIG welder. The main modified the following points: 1. An additional set of molten argon arc welding torch; 2. Wire feed motor and feed roller between the transmission ratio, from the original 16O: 1 to 96: 1; 3 Change the outer shape of the original serrated wire wheel, the left pressure wheel to 60 ° V-shaped groove, right pressure wheel knurl not groove;
