SMAW, also be well known as electrode arc welding, is a fusion welding method in which the arc is induced by the electrode and the welding parts are melted by the arc heat. It is the most widely us...
The demand for steel in modern society is constantly increasing. In daily life, many things are made of metal, and many metals cannot be cast at the same time. Therefore, it is necessary to use ele...
High-carbon steel refers to carbon steel with w(C) higher than 0.6%, which has a greater tendency to harden than medium-carbon steel, and forms high-carbon martensite, which is more sensitive to t...
