History of welding technology
Welding technology appears with the application of metal. The ancient welding methods were mainly casting welding, brazing and forging welding. The iron-edged brass cymbals made in Shang Dynasty in China were cast and welded by iron and copper. The copper-iron fusion line on its surface is tortuous and the combination is good. During the Spring and Autumn Period and the Warring States Period, there were many dragons on the bronze base of the drum in the tomb of Zeng Houyi, which were brazed in sections. After analysis, the composition used is similar to that of modern soft solder.
