The technique of repairing casting defects in Guizhou;


冷焊機,共同的缺點是,焊補效率不如電焊機和氬弧焊機高,但在修復毫米級缺陷和加工面缺陷時,其突出的優勢使人們更青睞于選擇冷焊.

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.


鑄工膠水:簡單,粗放的鑄件,一般修補處不需要后續加工,且沒有特殊的強度硬度要求。這類鑄件附加值比較低。

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.


焊補:90%以上的貴州鑄造廠家都選擇焊補來解決生產中遇到的鑄造缺陷。焊補修復因采用了金屬填充料(焊材一般與鑄件材質相匹配),焊補處性能基本可以達到母材的標準,且操作簡單,焊補效率高,受到許多廠家的認可和信賴。目前市場上,焊機種類比較多,應用在缺陷修復上,大體有以下幾種:

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.


電焊機:鑄鐵、鑄鋼件焊補多采用的傳統方式。

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


優點:修復大缺陷,效率高。

Advantages: repair large defects, high efficiency.


缺點:焊后焊點上硬度過高,內部有應力,容易產生裂紋,一般還需要退火熱處理才可以滿足加工要求。且因焊接條件限制,內部容易產生氣孔、夾渣等二次缺陷。

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.


氬弧焊:精密鑄件(合金鋼,不銹鋼精鑄件),鋁合金壓鑄件多采用氬弧焊機焊補。部分模具制造和修復廠家,也采用該焊機修復模具缺陷。

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.


優點:焊補效率高,精度較電焊機高。焊絲種類較多,不銹鋼、鋁合金產品上應用最廣??捎糜诤附?,強度教高。

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.
