The arc welding method of welding with manual welding equipment and electrodes is called manual arc welding. Manual arc welding uses the heat energy of the arc as a heat source. Under the heat of the arc, the electrode and the base metal are partially melted,welding machine manufacturer so that the welded part can achieve the purpose of atomic bonding.
Manual arc welding has the following characteristics:
1. Easy to operate, flexible to use and strong adaptability. It is suitable for welding of various steel grades, various thicknesses, various positions and various structures. Especially for irregular welding seam, short welding seam, overhead welding seam, high altitude and narrow welding seam, it can be used flexibly and operate freely.
2. The welding quality is good. Due to the high arc temperature, fast welding speed and small heat affected zone, the mechanical properties of the welded joint are ideal.
3. Manual arc welding can reduce deformation and improve stress distribution through process adjustment, such as jump welding, reverse segment welding, and symmetrical welding.
4. The equipment is simple and easy to use and maintain. Whether it is an AC welding machine or a DC welding machine, the welder is easy to master, reliable to use and easy to maintain. It is not as complicated as submerged arc welding and electroslag welding equipment.
