Abstract
In order to synchronize the at least two pulse welding processes performed simultaneously by welding devices in a multiple pulse welding process, the welding devices are connected to one another by a communication link and synchronization information is transmitted via the communication link from a transmitting welding device to at least one receiving welding device. The synchronization information is used in the receiving welding device to synchronize the pulse welding process performed by the receiving welding device with the pulse welding process performed by the transmitting welding device.
Claims14
A method for synchronizing at least two pulse welding processes for carrying out a multiple pulse welding process, whereas a pulse welding process comprises periodically at a pulse frequency repeated welding cycles having a pulse current phase and a base current phase, each pulse welding process being performed by a welding device, whereas the welding devices are connected to one another by a communication link and a synchronization information is transmitted via the communication link from a transmitting welding device to at least one receiving welding device and said synchronization information is used in the receiving welding device to synchronize the pulse welding process performed by the receiving welding device with the pulse welding process performed by the transmitting welding device, wherein the transmitting welding device transmits at least one synchronization pulse as synchronization information to at least one receiving welding device, whereas the at least one synchronization pulse is in a defined temporal relation to the welding cycle of the pulse welding process of the transmitting welding device, and the welding cycle of the pulse welding process of the receiving welding device is synchronized based on the received synchronization pulse.
An arrangement for carrying out a multiple pulse welding process by at least two welding devices for carrying out at least two pulse welding processes, whereas a pulse welding process comprises periodically at a pulse frequency repeated welding cycles having a pulse current phase and a base current phase, the welding devices being connected to one another by a communication link and whereas a transmitting welding device is designed to transmit a synchronization information via the communication link to at least one receiving welding device, the receiving welding device being designed to use said synchronization information to synchronize the pulse welding process performed by the receiving welding device with the pulse welding process performed by the transmitting welding device, wherein the transmitting welding device is designed to transmit at least one synchronization pulse, which is in a defined temporal relation to the welding cycle of the pulse welding process of the transmitting welding device, as synchronization information to at least one receiving welding device, and in that the receiving welding device is designed to synchronize its welding cycle of the pulse welding process based on the received synchronization pulse.
