Q. What are the two categories of automatic welding machine?

The two types of automatic welding machines are: semiautomatic and fully automatic. In semiautomatic welding an operator manually loads the parts into the welding fixture. A weld controller then keeps the welding process motion of the torch and stillness of the parts to pre-set parameters. When the welding done the operator removes the completed assembly and the process begins again. In fully automatic welding a custom machine or series of machines loads the work piece indexes the part or torch into position accomplishes the weld monitors the quality of the joint and unloads the finished product.
