Multi-welding-machine coordinated control device and method and welding system

Abstract

The invention provides a multi-welding-machine coordinated control device and method and a welding system. The multi-welding-machine coordinated control device comprises master-slave setting modules used for receiving master machine set instructions, setting any one of welding machines as a master machine and setting the rest of welding machines as slave machines according to the master machine set instructions, parameter transmission modules and phase position transmission modules. The parameter transmission module in the master machine is used for obtaining and outputting output waveform parameters of the master machine, and the parameter transmission modules in the slave machines are used for receiving the output waveform parameters output by the parameter transmission module in the master machine and transmitting the output waveform parameters to the slave machines where the parameter transmission modules are located. The phase position transmission module in the master machine is used for obtaining and outputting the output waveform phase position of the master machine, and the phase position transmission modules in the slave machines are used for receiving the output waveform phase position output by the phase position transmission module in the master machine and transmitting the output waveform phase position to the slave machines where the phase position transmission modules are located. According to the multi-welding-machine coordinated control device and method and the welding system, coordinated control output of alternating current and pulses of the multiple welding machines can be achieved, and synchronous output or fixed phase position difference asynchronous output can be achieved.

Description

technical field [0001] The present disclosure relates to the technical field of electric welding machines, and in particular, relates to a multi-welding machine coordination control device, a multi-welding machine coordination control method, and a welding system applying the multi-welding machine coordination control device. Background technique [0002] With the improvement of users' requirements on welding quality, welding speed and production output, the situation of multiple welding machines welding the same workpiece at the same time is increasing, and the problem of mutual interference between the arcs of multiple welding machines is also highlighted. Especially when the welding torches welded at the same time are very close on the same workpiece, or when the front and back sides of the same weld bead are welded at the same time, the mutual interference between the arcs will have a great impact on the welding effect and weld shape. Eventually lead to poor welding. ...
