TYPES OF METAL WELDING AND THEIR BRIEF DESCRIPTION
TYPES OF METAL WELDING AND THEIR BRIEF DESCRIPTION The technological components of the welding process were known as early as the 17th century. Then they were represented by casting and black smithing. "Modernization" began after the discovery of such a phenomenon as an electric arc. The development of welding received an additional impetus with the invention of a powder coating for electrodes. But the main leap fell at the end of the 20th century, when laser, ultrasound and plasma technologies became available. The introduction of electronics made it possible to automate the welding process, increase the accuracy of work and productivity. Currently, there are three types of welding, which differ in the type of energy used to perform the work: thermal; mechanical; thermomechanical.
