Efficient suspended wire grade electroslag welding system

Description:

Wire pole electroslag welding machine is an electroslag welding equipment that uses welding wire as electrode, and the wire is fed into the slag pool through the non-consumable electroslag welding gun and conductive nozzle. It is mainly used for efficient welding of vertical weld seams in steel structures, and is especially suitable for the welding of box-type columns and box-type beam bulkheads. It can weld very thick workpiece at one time, high welding speed, smooth welding process and not easy to produce spatter, with high melting rate.
Efficiency, high performance, stable and easy to operate

1. H7 Wire Electroslag Welding Power SourceSpecifications(IGBT)

2. Wire Feeder

3. Electroslag Welding Torch Lengths

System Features

1. Using only welding wire as filler material reduces welding costs.
2. The use of fine welding wire and high current density results in a deposition rate of up to 140g/min, and the weld is formed in one pass, resulting in high welding efficiency.
3. The use of an oscillator allows single-wire welding of plates up to 100mm thick (compared to other manufacturers, which only have a plate thickness range of 16-65mm).
4. Easy to operate: The electroslag welding torch automatically raises according to the preset current, allowing a single operator to simultaneously operate two or more machines. 5. Extremely low equipment maintenance and repair costs. Utilizing cost-effective, highly reliable components readily available on the market, the system minimizes end-user costs.
6. The specially designed welding current detection and control system is independent of the ammeter pointer (unlike the Watanabe meter used by other welding manufacturers, which relies on the ammeter pointer), resulting in vibration resistance, high accuracy, and high reliability.

7. Features include slow wire feeding for arc ignition and arc termination with ball trimming (FTT) for more reliable arc ignition and eliminates the need to trim the wire end ball after welding.
8. Features include motor overload and short-circuit protection to prevent component damage from motor stalls and short circuits.
9. Features include three-axis (ZHS) or two-axis (ZHS(L)) position adjustment, horizontal rotation, cross-direction tilt adjustment, and wire cross alignment, enabling convenient adjustment of the electroslag welding gun position and angle to align the wire end with the welding gun axis.
10. Features include a trolley travel lock interface for connection to the trolley control system to prevent trolley movement during welding due to misoperation.
11. Features include a cooling water abnormality alarm. If the circulating cooling water tank is not open, or the cooling water flow is significantly reduced, interrupted, or blocked, an audible and visual alarm is issued to the user, automatically stopping the welding process to prevent damage to the welding gun and water-cooling cable from overheating.
