“Welding” includes many different processes and systems.
MIG (Metal Inert Gas) welding involves the use of spools and MIG welding guns. This welding process is very good for both steel ...
Cast iron is an early used structural material. Many parts of mechanical equipment are made of cast iron. At the same time, the repair welding of cast iron parts is still a common problem.

First, Welding cracks and pores are generated.
The moisture absorbed by the welding rod becomes gas under the action of the welding arc heat, which decomposes hydrogen, resulting in the formation ...
The welding electrode is a metal rod that is melted and filled at the joint of the welding work-piece during gas welding or electric welding. The material of the electrode is usually the same as th...
