straight seam ERW steel pipe welding machine

The features of straight seam ERW steel pipe welding machine

1.Using new type electronics components (SCR,IGBT,MOSFET) as switch device of induction heating power, ithas the advantage of control simple and high efficiency,the whole efficiency more than 85% and power saving more than 30% compared with the vacuum tube,its the ideal choice to replace the vacuum tube induction heating power supply.

2.Semiconductor spare parts have no life limit, reduce the normal maintenance costs.

3.Use PLC and HMI link the power and production line real time monitor the whole production line.

4.Rectifier circuit using single-chip digital phase control technology, high integration, strong anti-jamming capability.

5.Inverter circuit using a new type of integrated circuit, phase lock control precision, the inverter circuit has strong ability to adapt the changes in load.

6.There have production in the rectifier and inverter circuit that insure the equipment and spare parts operation efficiency and safety.

7.All the equipment have short circuit;open circuit,connect ground, over current, over voltage and cooling system temperature testing before delivery which make the equipment running stable and safe.

8.Rectifier cabinet and inverter output cabinet adopt soft connection, this make installation and output way more easy.

Equipment composing

The whole set of solid state H.F. welder comprises of switchgear rectifying cabinet, inverter output cabinet, connecting optical fiber, circulation soft water cooling system, central operator console, mechanical adjustment device, contact welding pole plate and contact pin (contact welding) and etc.

Switchgear rectifying cabinet

Designed with integration of switchgear cabinet and rectifying part, besides achieving switchgear cabinet functions, it also has rectifying control functions of solid state H.F. welders.

Installed line-in switch, line-in current meter, voltage meter (can be switched) and line-in voltage indication lamp.

Installed 3-phase full-controlled thyristor Rectification Bridge to realize power adjustment of the HF welder.

Installed flat-wave reactor, flat-wave capacitor and filter to improve the flat-wave coefficient.

Inverter output cabinet

The inverter part is consisted of MOSFET single-phase inverter bridge connected in parallel. The power of single-phase bridge is 120kW; the inverter bridge adopts the building block method to realize power superposition. Every piece of bridge plates is designed in the shape of a drawer, which is very easy to install and repair.

The matching transformer is adopted for power combination, also it adopts the output method by of secondary resonance and non-welding transformer, tank circuit resonance capacitor (low voltage) resonates with the sensor directly, and the output pole plate offers required power transmission for pipe welding.

Adopted sealed equipment case, installed with air conditioner.

Central operation console

It realizes solid state H.F. welder remote operation and power regulation, installed with LCD which indicates armature voltage, field voltage indication and of DC drive and DC voltage, DC current indication of H.F. welders.

Circulation soft water cooling system

circulation soft water is used as cooling water with temperature and water level indicator and protection.

Mechanical adjustment device

Applied to install inverter output cabinet and adjust inductor position.

Q:What should be paid attention to when welding the air conditioner copper pipe welding machine?: The copper wire of the air conditioner is not long enough to be welded and connected. Will not affect the effect. The method is: after the direct cutting off, the connection head is connected, after connecting, welding, welding is good.

Q:What is the welding machine for glass fibre reinforced plastic cable protection tube?: Glass fiber reinforced plastic cable tube is mainly adhesive and socket connection, it can not be welded.

Q:Which brand is the best for plastic pipe welding machine? How to ensure the quality of PE pipe welding machine?: Domestic plastic pipe welding machine has a welding magic card do well, the price of foreign brands is too far off, and so it is used

Q:How to weld the air conditioner copper tube welding?: How can the air conditioning copper tube and copper pipe be welded?Copper tube and copper tube welding is generally used silver electrode (its silver content is 25%, 15% or 5%) or copper and phosphorus series welding rod, they all have good fluidity, do not need welding flux. Specific welding procedures are as follows:1) welding copper tube processing: expansion and deburring, old copper pipe must also use abrasive paper to remove oxide layer and dirt. When the diameter of the welded copper pipe is different greatly, it is necessary to clamp the pipe with big diameter in order to ensure that the gap between welds should not be too large.2) nitrogen filling: the copper pipe is filled with nitrogen to carry out welding, which can make the inner wall of copper tube bright, clean and oxide free, so as to effectively control the cleanliness of the system.3) open the welding torch, adjust the mixture ratio of oxygen and acetylene, and choose neutral flame.4) first heated by the flame tube insertion, slightly hot after the flame moves outward a little casing, heating the pipe when the pipe joint uniformly heated to the welding temperature (micro solder (red), adding silver electrode or phosphorus brazing). By the solder melting temperature, and flame temperature maintaining outer flame pipe joints, and not using pre solder melt drip welding joints, then heating welding, otherwise it will affect the strength and density of joints.5) remove the flame and close the torch. Check the quality of the weld. If there is a gap or a sand heel in the weld, re weld the weld
