(Summary description)Casting defects have always been a big problem that puzzled casting companies.Poorly resolved casting defects will affect the quality of castings.During the production of castings such as cast steel and iron,foundry enterprises will encounter various casting defects such as wear,scratches,sand holes,pinholes,cracks,defect deformation,hardness reduction,and damage.Currently,only remedial measures can be taken.These defects cannot be solved fundamentally.

Casting defects have always been a big problem that puzzled casting companies.Poorly resolved casting defects will affect the quality of castings.During the production of castings such as cast steel and iron,foundry enterprises will encounter various casting defects such as wear,scratches,sand holes,pinholes,cracks,defect deformation,hardness reduction,and damage.Currently,only remedial measures can be taken.These defects cannot be solved fundamentally.

At present,there are the following methods for the defects of cast steel and cast iron in China.The first is argon arc welding.This method is mainly for precision cast steel cast iron and aluminum alloy die casting.The welding repair efficiency is high and the accuracy is higher than that of electric welding machine.The second is the electric welding machine.This method is mainly aimed at castings such as cast steel and iron,which can repair larger defects and have higher efficiency.These two methods have their own defects,and some solutions will also produce secondary defects.Therefore,from the current point of view,the defects on the castings cannot be completely eliminated,and they can only be solved specifically for specific problems.

The above-mentioned problems are also related to factors such as the low production technology level of casting steel and other castings in China,and the low performance of the casting equipment used.With the improvement of the technological level of the casting industry in China and the improvement of the performance of casting equipment,I believe that this kind of hard The injury will be well resolved,at least it will not become a big problem that plagues casting companies.
