Characteristics of electric welding machine
Electric welding machine uses electric energy to instantly convert electric energy into heat energy. Electricity is very common. The electric welding machine is small in size, simple to operate, convenient to use and fast, and suitable for working in a dry environment without too many requirements. The advantages of strong welding after welding are widely used in various fields, especially for parts requiring high strength, which can instantly and permanently connect the same metal materials (or dissimilar metals, but with different welding methods).
After heat treatment, the weld seam has the same strength as the base metal and is well sealed, which solves the sealing and strength problems for manufacturing gas and liquid storage containers. During the use of electric welding machine, a certain magnetic field will be generated around the welding machine, and radiation will be generated when the arc burns. There are harmful substances such as infrared rays and ultraviolet rays in the arc, as well as metal vapor and smoke, so adequate protective measures must be taken during operation.
