Arc Welding Tips
The basic principle of arc welding is to use current to pass through the air gap between the welding rod and the workpiece to generate ionization and form a stable arc.The basic techniques of arc welding include three steps: arc ignition, rod transport, and arc closing. Each step has certain skills and requirements, which require the welder to master and use flexibly.
Arc ignition refers to the process of establishing an arc between the welding rod and the workpiece, and is the beginning of arc welding. The purpose of arc ignition is to cause current to pass through the welding rod and workpiece to produce ionization and form a stable arc.
Rod movement refers to the process of moving the welding rod along the welding direction and transversely under the action of the arc, so that the metal of the welding rod and the workpiece melts and fills the weld. It is the main step of arc welding.
Arc closing refers to the process of breaking the arc at the end of welding, which is the end of arc welding. The purpose of arc closing is to cool the metal of the weld smoothly and avoid welding defects such as arc craters and pores.
