摘要： Embodiments of welding systems and methods for reducing spatter in pulsed welding are disclosed. A welding power source includes a first welding output stud to be electrically connected to a consumable welding electrode and a second welding output stud to be electrically connected to a workpiece. Power electronics generate welding output current pulses. A switching network is connected between the power electronics and the first welding output stud. A controller is connected between the power electronics and the switching network. The controller controls the timing of each welding output current pulse and switches the switching network back and forth between a first welding output current flowing state and a second welding output current impeding state based on the timing. An increase in a decay rate of a trailing edge of each welding output current pulse is effected during the second welding output current impeding state.

摘要： There is provided an arc welding control method for performing a forward/reverse feeding control of alternating a feeding rate of a welding wire between a forward feeding period and a reverse feeding period, and generating short-circuiting periods and arc periods to perform welding. The welding wire is fed forwardly upon starting the welding. The forward feeding is continued during a transient welding period from a time point at which the welding wire comes in contact with a base material and conduction of welding current is started to a time point at which convergence on a steady welding period is performed. The transient welding period is terminated at the short-circuiting period. The forward/reverse feeding control is started from the reverse feeding period after the termination of the transient welding period.

摘要： The present invention improves the stability of arc welding carried out by cyclical repetition of forward feed and reverse feed of a weld wire, An arc welding control method includes repeated forward feed and reverse feed at a weld wire feed rate, according to a prescribed cycle and a prescribed amplitude, and generation of short-circuit time intervals and arc time intervals to carry out welding, wherein the feed rate cycle and/or the amplitude are set automatically on the basis of the average feed rate and the welding rate, or the wire deposition amount per unit of weld length. Further, in the event that the amplitude has changed, feedback control of the forward feed-side shift amount is carried out in such a way that the average value of the feed rate is constant. In so doing, the feed rate cycle and amplitude are always set to optimal values.

摘要： Welding power is generated by first generating two different current waveforms, and comparing the waveform values for control intervals to select which waveform provides the greater current. The waveforms are for different transfer modes, such as one for a pulsed arc portion, and another for a short-circuit transfer mode or for short-circuit clearing. The waveforms may be programmed by settings in a state machine. A balance or relative prioritization in the comparison may be influenced by user inputs. The resulting hybrid process has aspects of both spray transfer and short-circuit transfer modes.

摘要： A welding regime may implements cyclic short circuits under a closed loop voltage control approach. Upon clearing or imminent clearing of the short circuit, a current recess is implemented. The current recess reduces the current that would otherwise be applied to the weld, resulting in multiple benefits. The recess may be implemented by suspending voltage command signals. Following the current recess, normal control is resumed with the then-current voltage command.

摘要： Embodiments of the present invention comprise a system and method to weld or join coated materials using an arc welding system alone, or in combination with a hot wire system, where the arc welding system uses a welding current having an AC current portion to build a droplet for transfer to the workpiece. In further embodiments, the workpiece is coated with a material, such as zinc, and the arc welding system uses an AC welding waveform which is capable of welding coated workpieces with little or no porosity or spatter and can achieve enhanced performance. Additional embodiments use an enhanced electrode to provide optimum porosity performance. Such embodiments allow for the welding of coated material with little or no porosity and spatter, and at a high welding rate.

摘要： For the determination of the welding current to be used for the resistance welding of the overlap seam of container bodies, welding with a test body is carried out with a changing strength of welding current which in the test body produces a varying welding of the seam. The current strength varies from welding of this seam with a too high temperature to welding with a too low temperature. Along with this the welding current strength used in the welding is determined so that it is further determined at which point of the seam the welding has been accomplished and with what strength of welding current. By means of a mechanical and/or optical investigation of the welded seam it can then be easily determined where the seam has been correctly welded for the series production of container bodies from the same sheet material as the test bodies. When such a point or such a region of the seam is known the welding current used in the test welding can be taken as the welding current for serial production.
