贵州铸造缺陷修复的技巧;

贵州铸造厂

The technique of repairing casting defects in Guizhou;


冷焊机,共同的缺点是,焊补效率不如电焊机和氩弧焊机高,但在修复毫米级缺陷和加工面缺陷时,其突出的优势使人们更青睐于选择冷焊.

Cold welding, common shortcoming, welding efficiency as welding and argon arc welding machine is high, but in the repair of millimeter level defects and machined surface defects, its outstanding advantages that people prefer to choose the cold welding.


铸工胶水:简单,粗放的铸件,一般修补处不需要后续加工,且没有特殊的强度硬度要求。这类铸件附加值比较低。

Casting glue: simple, rough castings, general repair department does not require subsequent processing, and no special requirements of strength and hardness. The added value of this kind of castings is relatively low.


焊补:90%以上的贵州铸造厂家都选择焊补来解决生产中遇到的铸造缺陷。焊补修复因采用了金属填充料(焊材一般与铸件材质相匹配),焊补处性能基本可以达到母材的标准,且操作简单,焊补效率高,受到许多厂家的认可和信赖。目前市场上,焊机种类比较多,应用在缺陷修复上,大体有以下几种:

Welding repair: more than 90% of the Guizhou foundry manufacturers have chosen welding repair to solve the casting defects encountered in production. Repair welding by using filler metal (welding generally matched with casting material), welding performance can basically meet the standard of the parent material, and has the advantages of simple operation, high welding efficiency, many manufacturers have recognized and trusted. At present, there are many kinds of welding machines in the market, and there are several kinds of defects used in the defect repair.


电焊机:铸铁、铸钢件焊补多采用的传统方式。

Electric welding machine: the traditional way of welding and filling of cast iron and cast steel.


优点:修复大缺陷,效率高。

Advantages: repair large defects, high efficiency.


缺点:焊后焊点上硬度过高,内部有应力,容易产生裂纹,一般还需要退火热处理才可以满足加工要求。且因焊接条件限制,内部容易产生气孔、夹渣等二次缺陷。

Shortcomings: the hardness of the welding spot is too high, the internal stress is stressed, and the crack is easy to produce. In general, the heat treatment is also needed to meet the processing requirements. And because of the limit of welding conditions, it is easy to produce two defects, such as gas hole, slag and so on.


氩弧焊:精密铸件(合金钢,不锈钢精铸件),铝合金压铸件多采用氩弧焊机焊补。部分模具制造和修复厂家,也采用该焊机修复模具缺陷。

Argon arc welding: Precision Casting (alloy steel, stainless steel casting), aluminum alloy die casting is mostly used for welding of argon arc welding machine. Some moulds are made and repaired, and the welding machine is also used to repair the defects of the mould.


优点:焊补效率高,精度较电焊机高。焊丝种类较多,不锈钢、铝合金产品上应用最广。可用于焊接,强度教高。

Advantages: high welding efficiency and higher precision than electric welding machine. There are many kinds of welding wire, and the most widely used in stainless steel and aluminum alloy products. It can be used for welding, and the strength is high.
