          钣金加工之焊接方面的基础了解与认识

          1、钣金加工的焊缝坡口的基本尺寸  焊缝坡口要合理,这样才能够保证尺寸精度,以减少焊接变形。

          2、焊接结构(1)在焊接时,不允许进行长焊缝连续焊接,应进行交替断续焊接,以免出现热变形,从而影响到焊接质量。(2)焊条应能够保证进入焊接区,而且要倾斜45度才行。

          3、焊接准备  (1)焊接劳动?;び闷芬急负貌判?,还要对焊接设备、焊条等进行检查,是否符合规定要求,有无问题。(2)焊件上的铁锈、油脂及水分等,应清除干净。

          4、工艺参数

          焊接的工艺参数,主要有焊条直径、焊接电流、焊接电压以及焊接速度等。

          焊条直径:与焊件厚度、焊接接头以及焊缝位置有关。

          焊接电流:应根据焊条直径,并参照焊机操作说明书来进行确定。

          电弧电压:它是与电弧长度成正比的。
