Welding line
H-beam welding line,Pipe welding line or other steel building materials machinery

  High Frequency Welded Pipe Unit: Feed steel strip of a certain specification into the machine and then use forming roll to crimp the steel strip into pipe-blank. Then under skin effect and proximity effect of high frequency electric current, induced electricity is concentrated onto the bonding surface of the pipe profile fringe and heat up the pipe profile fringe quickly to the welding temperature and finish welding under the pressure of the squeeze roller. After cooling, sizing and broad straightening, you can get the steel pipe of needed specification. Our products such as roll forming unit,forming unit, cage forming unit can produce X80 and J55 API petroleum casing pipe and petroleum and gas pipe, which conform to the standard of API-5L,API-5CT. This unit can also produce special pipes for air cooling condenser used by electric power plant or steel mill. Equipment composition: uncoiler, unbender unit, active flattener, cutting & butt welder, storing device, forming and sizing unit, flying saw, end milling equipment, hydrostatic testing machine, charge table, inspected equipment, sack & bale machine, high frequency DC, product line electric appliance

  This welding line for H-profile steel is a new technical product that integrates mechanical, electric, and pneumatic technologies. The machine, using advanced technology of single-arc double-wire welding, greatly increases the product efficiency. It consists of welding machine, position fixing machine and conveyer. After fixing the position for the web and two wings of H-profile steel, the welding machine can automatically located, clamp, adjust, weld, transport until finishing the all work. The automatic mode of this line greatly lowers the cost of manufacture. Main parameters A. Operation height: About 750mm B. Dimension of conveyor: About 2000 X 15000mm C. Dimension of main frame: About 1000 X 3500mm D. Hydraulic motor power: About 5.5KW H-profile specifications A. Main welding speed: 500-2000mm/min B. Inclination of H-profile steel: 8degree (unilateral) C. Web thickness: 3-8mm D. Web width: 300-1200mm E. Web length: 2000-15000mm F. Wing thickness: 5-16mm G. Wing width: 150-500mm H. Wing length: 2000-15000mm Working flow: Put the wing panel on the conveyor---oil vat for turning the wing panel work---upright the two wing---oil vat for turning wing panel reposition ---oil vat for lifting work---wing panel lifting---put the web panel on the conveyor ---oil vat for lifting descend ---web panel and two wing panels on the conveyor ---adjust them as requirement---spot weld the head of three panel and let them to be H-profile.
