Information

Everyone has heard of electric welding and may be relatively new to the word welding. Welding is a special word in the production of die casting, which refers to the interaction between castings and molds. When starting the mold, a part of the casting remains on the surface of the mold, resulting in a casting defect in which the casting lacks meat. It is a very harmful and difficult problem in the production of die casting. The formation and expansion of the welding between the die casting mold and the aluminum casting not only reduces the surface quality and dimensional accuracy of the aluminum casting, but also can cause the scrap of the aluminum casting and even lead to the early failure of the mold. At the same time, welding also increases the repair time of the mold and the labor intensity of the workers, greatly reducing labor productivity. Recently, people have begun to pay attention to the welding phenomenon, and some experimental methods have been used in the laboratory to study this phenomenon, so that people have a certain understanding of the welding phenomenon.

At present, there is no in-depth study on the formation mechanism of the welding phenomenon. People only put forward some simple assumptions and speculations based on the specific conditions of this phenomenon in the production of die casting, and summarize some of the factors that affect the formation and expansion of welding Factors, and for these factors, some measures have been taken to prevent the formation of welding. As for the specific effect, it still needs to be tested in practical applications.
