表面堆焊技术表面堆焊技术surface bead welding technique表面堆焊的零件,因基体和表面有不同性能而获得良好的综合技术性能,既能充分利用基体材料的潜力,又显著地提高零件使用寿命,减少贵重合金的消耗。堆焊修复的内燃机气门的费用仅是新气门的30%,而使用寿命却比新气门提高l倍。20世纪70一80年代以来,堆焊合金已有数十种,堆焊焊条已形成系列产品,合金粉末、合金焊丝、新型堆焊焊条等正在迅速发展;各种电弧焊方法在堆焊工作中得到采用。此外,带极堆焊、管状焊丝堆焊、双丝等离子堆焊和高频堆焊等高效堆焊技术也在研究应用中。在农机修理业中,手工电弧堆焊,氧一乙炔焰堆焊,埋弧堆焊.二氧化碳(C02)保护堆焊,粉末等离子堆焊,氧一乙炔焰粉末喷焊,高颇感应堆焊等表面堆焊技术,已得到比较普遍的应用。手工电弧堆焊农机维修的主要堆焊工艺。使用实芯焊条或管状焊芯焊条,可获得几乎所有的堆焊合金成分。堆焊修复的零件有中碳钢制造的各种轴类,履带拖拉机的行走系零件,如履带板、驱动轮、齿轮等件。焊条有结422、结5肠、堆212、堆256等多种规格,可适应不同性能要求。缺点是生产效率低,焊层中合金成分稀释率高,不易获得薄而均匀的堆焊层。但应用的设备简单(交、直流电焊机),成本低。氧一乙炔焰堆焊用氧炔焰焊枪熔化金属丝材,在零件表面形成焊层。氧一乙炔沮度较低(3050一3 100℃),火焰功率和性质可以调节.焊层合金稀释率较小(l~10%),能够得到1毫米以下的均匀薄层。方法简便、成本低。修复的主要零件是内燃机气门、凸轮轴、犁铲等。堆焊材料一般利用废气门或轴承外环锻成的焊条,也可采用专用焊丝。丝101属高铬铸铁,含铬25一31%,焊层硬度高耐磨性好。在500℃以下能保持较高的硬度,耐腐蚀,抗氧化,但抗裂性能差,焊前需预热500℃。埋弧堆焊在熔剂层保护下的电弧自动堆焊(图)。主要用于修复拖拉机中的轴和轮类零件,如曲轴、履带拖拉机的支重轮、后轴、引导轮等。堆焊采用平硬外特性的直流电源,正极接焊丝.零件与负极相连并作回转运动,焊丝作纵向运动。焊剂堆撤在焊丝端部周围。焊丝和零件表面间的电弧热量使周埋弧堆焊工作原理示意图围的焊剂熔化,焊剂燕汽将熔化的焊剂排开,形成封闭的空间,电弧与空气隔绝并在此空间燃烧。
