Inverter welding machine work process

The three-phase or single-phase AC power frequency rectifier, after filtering to get a smoother DC, the IGBT inverter circuit composed of the DC into tens of KHZ AC, the main transformer step-down, and then rectified filter Get a smooth DC output welding current.


Because of the high frequency inverter work, so the main transformer core cross-sectional area and greatly reduce the number of turns of the coil, therefore, inverter welding machine can be very smooth in the flow of cutting metal material, reduce the size and weight, greatly reduce power consumption , More importantly, inverter welding weight measurement length of the micro-second time to adjust the output current, so that will be able to make the ideal process of welding the ideal control process required to obtain satisfactory welding effect.




Although the circuit is closed, it is precisely because the circuit is closed to be closed in the whole circuit and the current is equal everywhere; but the resistance across the ground but not the same, especially in the unfixed contact resistance of the largest resistance in the physical Call in the resistance. In accordance with the law of thermal effects of current (also known as Joule's law), Q = I side Rt shows that the current is equal, the greater the resistance of the higher fever, welding welding electrode contact is also connected to the metal body contact Department at the receiving resistance of the largest, then in this part of the electric heat generated is naturally the most, the electrode is the lower melting point of the alloy, easy to melt naturally, the molten alloy electrode core with the object to be welded after cooling , Put the welding object bonded together.




Because the inverter welding machine is a typical switching power supply (output characteristics have great features), the output power, changes in work conditions, so the quality requirements of components is better, so that the work of gas package Governor stable, long life.




The advantages of inverter welding machine




    Due to the high frequency of inverter work, the main transformer core cross-sectional area and greatly reduce the number of turns, therefore, inverter welding machine can largely save the metal material, reducing the size and weight, greatly reducing power consumption, more Importantly, inverter welders are able to adjust the output current at subtle levels of time so that the ideal control process required for the welding process can be achieved with satisfactory welding results.




Inverter welding machine structural characteristics




     Welding head is the energy output of welding energy equipment converted into welding heat, and continue to send welding materials, while the head itself moves forward to achieve welding.




1. Manual arc welding with the welding clamp, with the melting electrode, the hand must continue to feed into the electrode down, and move forward to form a weld.




2. Automatic welding machine has automatic wire feeding agencies, and the head walk mechanism to move the nose forward. Commonly used trolley and hanging head two.




3. Resistance spot welding and welding convex welding head is the electrode and its pressure mechanism for the workpiece to exert pressure and power.




4. Sew another drive mechanism to drive the workpiece to move. Need to be welded when the static and dynamic fixture and fixture clamping mechanism, as well as moving fixtures and forging institutions.
