Maintenance status and analysis of machinery and equipment. Casting glue: This is the company's instinctive selection of casting repair parts. Its key features are simplicity, convenience, low price, and low requirements for employees. However, this method is only suitable for rough casting parts. Generally, the repaired parts cannot be processed after the product is processed, and the separated compressive strength is very low. This processing method is only suitable for simple, extensive casting or casting with low value added. With the progress of forging industry production, caster glue is becoming less and less suitable for customers.

It is really the selection of welding and repairing materials for each foundry to solve the welding defects encountered in use. Casting repair welding repair is to choose welding material generally meets the casting material with the metal material to fill the master batch, and then meet the basic physical performance standards required by the pregnant mother. A variety of methods are required for repair welding; the repair welding method is simple; the repair welding efficiency is high, the repair welding cost is low, the air pollution is small, and the post-repair welding treatment is simple. Only in this way can it be accepted and trusted by the foundry. In the current sales market, there are many types of secondary welding machines for personal repair welding of castings, and there may be the following types.

DC welding machine is an indispensable mechanical equipment in the production of steel rolling. It uses the arc generated by the arc to melt the stainless steel electrode and the welding material when a short-circuit fault occurs in an instant, so as to achieve the purpose of melting. It belongs to the traditional welding method, usually used for repair welding of pig iron, stainless steel castings or some traditional electric welding repair welding.

Advantages: suitable for working in a boring natural environment, without too much request, relatively small size, easy to operate, easy to use, fast, strong after electric welding and electric welding, suitable for large-scale electric welding repair welding. The same metal materials (different metal materials can also be butted in an instant, but the electric welding and welding methods are different). The welding is heat-treated, and the compressive strength is the same as the welding seam, and the sealing performance is very good.
