galvanized square pipe high frequency seam welding machine

1.Features of Carbon steel tube mill solid state HF welder

1.1 The solid state H.F. welder adopts Germany IXYS company IXFN38N100Q2 38A/1000V high-power MOSFET and DSEI 2×61-12B 60A/1200V rapid recovery diode to compose series type invertible circuit.

1.2 The solid state H.F. welder adopts modularization design with more compact structure which makes maintenance and high-power realization much easier.

1.3 It has particular technology of bridge-divided over-current protection that guarantees equipment safety.

1.4 It combines international advanced control method of same products, adopts advanced technologies like fixed angle phase-locking control, upper frequency limit/lower frequency limit lock-lost protection and etc. With these technologies, the equipments run more stably, more efficiently, more accurate and effective protections to the inductor short-circuit and open-circuit malfunction during pipe welding production.

1.5 Speed-power closed-loop control system which is an optional installation to user, it highly improves welding efficiency and reduces technics adjustment period.

1.6 Line-in end of solid state H.F. welder does not need step-up /step-down rectifier transformer, compared with vacuum tube welder and parallel type welder; it has significant energy-saving effects (Under same welding condition, energy-saving ≥30% compared with vacuum tube welder).

1.7The solid state H.F. welder designed with the most advanced electric-load-matching technology (PS+PWM control) which keeps solid state H.F. welder on a high welding efficiency, high power coefficient (>0.9), optimizing load matching status and can be switched under induction welding/contact welding double function mode.

2. Circuit structure of the inverter welder machine

3.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.

Q:What should be paid attention to when welding the air conditioner copper pipe welding machine?: Don't let out the water,

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
