Double Tandem Simplified Electroslag Welding Granty
SESNET is the abbreviation of Simplified Electroslag Welding Process with Non-consumable Elevating Tip. The elevating tip of guide wire is non-consumable, when welding; the current sensing can rise automatically.
  1. Applicable thickness: 16~150mm.
  2. Applicable material: Soft steel and 50kg high tensile strength steel.
  3. Weld bead shape: Square and rectangle.
  4. Applicable length of weld bead: The longest 1500mm.
  5. Joint shape: T-joint and butt joint.
  6. Use USA-Lincoln DC and gas shielded arc welding machine to make welding system stably.

Basic technology parameter:

  1. The dimension of processed material
  • The width of flange plate (a): 400mm~1200mm
  • The height of web (b): 400mm~1200mm
  • The length of section: 4000mm~15000mm
  • The weight of section: Max 30 Ton
  1. Operating parameter
  • Track gauge: 3000 mm
  • Speed: 0- 5500mm/min
  • Distance: 18000mm 
  1. Equipment structure
      Gantry part
  • Moving electric motor (DC motor 1 HP + reducer): Controlled by a single controller with two DC motors,which connected to reducer and the wheels transmission system directly, that makes the trolley bilateral synchronous transmission and run stably while welding. The design reduced unnecessary drive parts and it is easier to maintain.


  • Transverse adjustment
  • The rising drive of elevating tip
  • Wire straightening device
  • Relay box
  • Cable and Pipe
  • Arc of oscillation device
  • Operation box

      The welding gun with gravity pressure guiding device to make the welding gun can move vertical and horizontal
      along the weld bead. It also has fine adjustment function (±50MM) and angle fine adjustment. It is easier for
      operators to welding.
