第一次全国机械设备维修技术会议上指出,电磁振动电弧堆焊是修复磨损零件的有效方法。我厂根据设备维修工作的需要,在领导支持下,通过三结合,学习外厂经验,结合我厂具体条件,摸索制造了一套细焊絲二氧化碳气体保护电磁振动电弧堆焊(以下简称细焊絲堆焊)设备,且对堆焊的工艺参数进行了探索验证,并已投入生产,其外形照片见封面。现介绍于下。一、细焊絲堆焊设备的工作过程细焊絲堆焊是利用电弧热量,熔化焊絲和工件金属,在二氧化碳气体保护介质中进行的自动电弧焊,并在较高的振动频率下,焊絲以很小的熔滴向工件表面过渡,从而获得薄而均匀的堆焊层。该设备的装置示意图如图1,它的工作过程如下:
The first National Machinery and Equipment Maintenance Technology Conference pointed out that electromagnetic vibration welding surfacing is an effective method to repair wear parts. According to the needs of equipment maintenance work, under the support of the leaders, our factory explored and manufactured a set of fine wire carbon dioxide gas protection electromagnetic vibrating arc surfacing (hereinafter referred to as the fine wire pack Welding) equipment, and the welding process parameters were explored and verified, and has been put into production, the appearance of photos, see the cover. Now introduced in the next. First, the welding wire welding equipment work process Fine wire welding is the use of arc heat, melting wire and the workpiece metal in the carbon dioxide gas protection medium for automatic arc welding and high vibration frequency, the wire to a very small Of the droplet to the workpiece surface transition, so as to obtain a thin and even surfacing layer. The equipment schematic diagram shown in Figure 1, the working process is as follows:
