The application of welding machine in galvanized steel material

Galvanized sheet is refers to the surface has a layer of zinc plated steel plate. Galvanized steel is to prevent the steel plate surface from corrosion to extend its service life, in the steel plate surface coated with a layer of metal zinc, the zinc coated steel plate are called galvanized sheet. Galvanized is a frequently used economic and effective anticorrosion method, about half of the zinc production in the world are used in this process.





galvanized steel galvanized layer not only has a physical shielding effect, and also played the electrochemical protection for steel matrix, and its good corrosion resistance for galvanized steel is widely used in many fields.

however, due to the existence of the galvanized layer in the galvanized steel, the galvanized steel welding technology greatly reduced, in the process of the welding of galvanized steel, zinc coating and the substrate steel physical properties have great difference, zinc plating steel melting gasification will take precedence over matrix, and thus in the welding process has a great influence on the quality of the galvanized steel.

at present, the main welding galvanized steel product has 3 kinds: the resistance welding, argon arc welding and welding, the traditional resistance welding and argon arc welding welding galvanized sheet, the platoon walk around every evaporation of zinc galvanized layer of molten metal, or in the form of bubbles in the weld, which results in the weld defects such as blowholes, cracks, leading to weld tensile strength is very low.

belongs to high energy beam welding technology and welding, with high energy density, high welding efficiency and weld deep wide than the big, small heat affected zone and the thermal deformation of small, energy saving etc, and is very suitable for the requirements of precision welding technology, and is widely used in the process of production and processing a way of welding.

ZuoLong machinery research and development production of galvanized steel sheet welding machine controlled by industrial control computer, high welding speed, welding strength is generally higher than that of parent metal, welding, plating zinc low dissipation, good adaptability to complex structure, easy to realize remote welding and automation.
