Solid State IGBT H.F. Welder welding carbon steel tube straight seam ERW tube mill equipment rectangle & square pipe production

IGBT Solid State H.F.Integrated Welder

Diode all wave rectifying add IGBT chopping to replace SCR rectifying,it’s improving the power factor;The DC part and inverter part into one cabinet,which reduce the waterway and circuit between the cabinets,which is effectively avoiding the electrical interference and reducing the installation time.

The inverter part is consisted of MOSFET single phase invert bridge in parallel style.Each bridge’s design power is 120kW/60kW.We adopt building block mode to pile up power,it’s very convenient to install and maintain because every single bridge board is designed as drawer structure consisted of slideway.

We adopt matching transformer to realize power combination,also we adopt sub-resonance,no-welding transformer output mode and make resonance directly by tank resonance capacitor (low voltage) and inductor to achieve steel pipe welding power transmission bu output lead.

Use sealed box and install overhead air conditioning.

Advantage :4S

1.Save power: Save 15%~25% of electric power than the 2nd generation welding machine. 2.Save time: Only take one day to install. 3.Save space: Save 60% workshop space. Save cost: Save cable lines, water pipe and cable trays between DC cabinet and inverter cabinet.

Central Console

The console achieves remote control and power regulation of solid-state H.F welder,installed with LCD;also it has indicators of armature voltage,field voltage on DC drive cabinet and indicators of DC voltage,DC current on welder.Installation of power-speed closed loop control function is optional.The console has design difference according to different types and quantities of matching DC drive cabinet.

Mechanical Adjusting Equipment

2-D adjustable bracket.For induction welding mode,applied with installation and adjustment of inverter output cabinet, the inductor position can be adjusted manual.

Water-water cooler

The water -water cooling system is composed of heat exchanger with the adoption of the special corrugated structure which makes the soft water form sharp turbulent flow in order to strengthen heat exchange.The system holds the advantages of compact design,small area occupation,convenient dis-mounting and high efficiency of heat exchange. Only with the ability of heat exchange but not cooling,it is necessary to use external circulation system to accomplish the heat exchange.

Air-water cooler

Model GPKL-II circulation soft water cooling system adopts closed cooling tower structure.Cooling soft water flow in sealed water tank and cooling pipes.The inner circulation soft water is cooled by overhead fan and water-spray method using the principle of absorbing heat when evaporation.The spray water store at the bottom of cooling tower,soft water circulate inside the closed cooling tower’s heat dissipation pipe,spray-water spray at pipes ’s surface by spray-water distribution system and sprayer through spray system,some heat is taken by dissipation and soft water temperature, inside the pipe go down accordingly. The cut board stops water in hot air and undissipated water, make them flow through PVC heat exchange layer ,the water in the layer in cooled by air,then temperature goes down and fall down to the bottom of the tower.
