利用堆焊法制造刀具、模具及各种工具,是一种节约贵重钢材的有效方法,目前我国机器制造业中,已开始在实际生产中应用。但是这种堆焊法,由于焊条种类的限制,在生产中应用的范围还很小,同时效率低,焊条的消耗量很可观。譬如,堆焊一把φ170×500的16齿铣刀,需要高速钢焊条30公斤左右,实际堆焊时间(不包括预热去渣的时间)达35～40小时以上。因此如何进一步降低堆焊成本,提高堆焊效率,是目前一个很重要的工作。针对这一问题,我们进行了“混合堆焊法”的试验,解决了这一问题。
The use of surfacing welding tools, molds and various tools, is an effective way to save valuable steel, the current machinery manufacturing industry in China, has begun to be used in the actual production. However, this method of surfacing, due to electrode type restrictions, the scope of application in production is still small, while low efficiency, the consumption of electrodes is considerable. For example, surfacing a φ170 × 500 16-tooth cutter, the need for high-speed steel electrode about 30 kg, the actual surfacing time (excluding warm-up time to slag) for 35 to 40 hours or more. Therefore, how to further reduce the cost of surfacing and improve the efficiency of surfacing is a very important task. In response to this problem, we conducted a “hybrid surfacing” test to solve this problem.
