摘　　要：针对加氢高(低)压空冷器管箱结构,研制了能在水平位置同时对管箱两条内角缝自动焊的焊接专用机。可焊管箱的最小空间尺寸为100mm×76mm,最大长度为3200mm。配制了脱渣性与抗裂性较好的焊剂;采用了加特型焊剂垫的工艺措施,解决了坡口钝边厚时不易焊透、钝边薄时易焊穿的问题。焊出了合格的产品。Facing with structure of high pressure air cooler tube box, an auto-special-welding machine is developed for welding two inside fillet welds of air cooler tube box at the same time on flat position. The minimum space dimension to be welded is 100mm×76mm, the maximum length 3200mm. The flux with better de-slagging and anti-cracking properties is chosen and an unique flux backing is used in order to overcome lack of penetration or burn through problems on root face of groove. The acceptable products are welded with the procedure and equipment developed.
