Product Description

High Efficiency Submerged Arc Welding Automatic H Beam Welding Machine
Steel structure has become one of the important structural forms of modern buildings with its obvious advantages of "light, fast, good, and economical", and has been widely used in super high-rise, large-span infrastructure, marine engineering, electric power, residential and other fields.

Welding technology is widely used in the field of building steel structures, and the quality of welding has a huge impact on engineering safety and use functions.
Some new and more efficient steel structure welding methods, such as electroslag welding, multi-wire gantry steel beam submerged arc welding, etc., have been gradually introduced into steel structure construction and production enterprises, providing more choices for enterprises to improve production efficiency and reduce production costs.

The main advantages of H-beam submerged arc welding are as follows:
(1) The welding current used is large and the input power is large. High thermal efficiency and large penetration. The groove of the workpiece can be smaller, reducing the amount of filler metal.
Single-wire submerged arc welding can penetrate 20mm at a time without the bevel of the workpiece.
(2) The welding speed is high.
Taking the butt welding of steel plates with a thickness of 8 to 10 mm as an example, the single wire submerged arc welding speed can reach 50 to 80 cm/min, and the manual arc welding does not exceed 10 to 13 cm/min.
(3) The presence of flux can not only separate the contact between the molten metal and the air, but also make the molten pool metal solidify more slowly. Reduce the possibility of defects such as pores and cracks in the weld.
Flux can also add some alloying elements to the weld metal to improve the mechanical properties of the weld metal.
