When the thickness of the welded stainless steel plate reaches 1.2 millimeters, how should the duty ratio be adjusted so that the welding can achieve the best effect?! Thank you
Characteristics of pulsed direct current
Duty cycle is the ratio of pulse turn-on time and total timeTo put it bluntly, a water pipe has been let off, and can run one side of water a minute;Then you run 30 seconds per minute, 30 seconds off, you can only run half square water, the duty cycle is the opening time divided by the opening and closing time, and that is, 30 divided by 60 is 0.5When you need the high temperature steel plate welding duty ratio increase, but you have to look at the instructions of how much or hold their own, because you do not know what the first machine models, how much power, so you see, anyway, the larger duty ratio, the higher the temperature of welding - this manual must yes, you look fine.
Duty cycle refers to the ratio of the time of the pulse signal to that of the energizing period. In a sequence of ideal pulses (such as Fang Bo), the ratio of the duration of the positive pulse to the total period of the pulse.The duty cycle (Duty, Ratio) has the following meanings in the telecommunication field:For example: pulse width 1 s, signal cycle 4 s pulse sequence, duty cycle is 0.25. The ratio of the time occupied by a pulse to the total time in a continuous working period. In CVSD modulation (continuously variable slope delta), the average ratio of bits (1) is not complete.In a periodic phenomenon, the ratio of the duration of a phenomenon to the total time. For example, there is a phrase in the idiom: "three days fishing, two days net drying", if five days as a cycle, "fishing" of the duty cycle is 3/5.The control precision of modern automobile more and more high, especially in the electronic control system, implementation of some common switching devices previously used by the modern car has been unable to meet the control requirements, such as EGR system, idle speed control system, fuel evaporation control system etc.. Precisely, the duty should be called electronic pulse width modulation technology than the control, it is to add pulse width modulation in the execution of the work voltage signal components in a certain frequency through the electronic control device, in order to achieve the implementation of components working state control precision, continuous control. In recent years, the linear EGR system adopted by Shanghai GM Buick car is actually using this technology to realize the linear switching function of the EGR valve. Then why will the electronic pulse width modulation technique called duty ratio control technology, in fact, the duty ratio of the pulse width modulation control is extended, the duty ratio is controlled by a circuit connected to the percentage of the whole circuit cycle time.
