Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings.

[0009] An electroslag welding device with a tubular melting nozzle for steel structure high-rise building construction, which consists of a feed roller (1), a tubular melting nozzle (2), a drug coating (3), a water-cooled copper block (4), and a slag shell on the surface of the weld ( 5), welding wire (6), motor (7), tubular nozzle holder (8), slag pool (9), molten metal (10) and weld seam (11), the electroslag welding is a For automatic welding, electroslag welding first generates an arc between the electrode and the arc striker, and uses its heat to melt the surrounding flux and turn it into liquid slag. When the liquid slag reaches a certain depth in the space between the weldment and the cooling slider (forming the slag pool (9)), the arc is extinguished, and the arc process is transformed into an electroslag process. When the welding current passes through the sla...

The tubular dissolved nozzle electroslag welding device is composed of a feed-in pressing wheel, a tubular dissolved nozzle, a drug skin, a water cold copper block, a welding seam surface slag shell, a welding wire, an electric motor, a tubular dissolving nozzle holder, a slag pool, a melting metal and a welding seam.

Description

Technical field: [0001] The invention relates to a steel structure high-rise building construction, and a tubular melting nozzle electroslag welding device for steel structure high-rise building construction. Background technique: [0002] All the three actions of sending, advancing and swinging the electrode are all realized by manual operation. It is called manual arc welding. It is a welding method commonly used in steel structures. Its equipment is simple, and its operation is flexible and convenient. Welding, but the production efficiency is poor and the quality is low. It is generally used as a weld primer in the manufacturing process of steel structure high-rise buildings. It is a widely used welding technology in on-site welding. Invention content: [0003] The object of the present invention is to provide a tubular melting nozzle electroslag welding device for steel structure high-rise building construction in order to overcome the defects of the prior ar...
