The utilization of multi specification functions in the controller of resistance welding equipment
In actual production, resistance welding equipment often requires multiple welding points on many welded workpieces, and the specifications of each welding point may be different. If only the control box button is adjusted, the efficiency will be greatly affected, and the labor intensity of the operator will be increased. There are also various switches installed, such as foot pedals and manual switches, to deal with it. However, in practical applications, it is easy to make mistakes and cause poor welding quality of workpieces. If we were to add another spot welding machine, the cost would be too high.
Actually, we all know that the endurance rate of resistance welding equipment is generally between 20-50%. Some machines even operate at 100%, and the working time of resistance welding equipment is usually a few tenths of a second, so most of the power is not used. In view of this situation, we can choose to purchase resistance welding equipment such as two head spot welding machines, three head spot welding machines, or even four head spot welding machines. The role of gantry welding machines is similar. For welding parts with different specification requirements, one operator completes one specification and hands it over to the next operator, and the process is carried out sequentially until all are completed.
The emergence of multi station resistance welding equipment has greatly improved the utilization rate of spot welding machines and reduced the procurement cost of spot welding machines. At this point, it is very practical for the spot welding machine controller to simultaneously call the multi specification function, which can store multiple sets of specifications at once and set corresponding welding parameters for each workstation.
According to the continuous improvement of welding process requirements by manufacturing enterprises, in order to meet market demand. The controllers of current resistance welding equipment have the characteristics of multi pulse triggering, multiple welding specifications, multiple starting methods, multiple on-site data monitoring, accurate control time, small welding current error, and stable operation. But increasingly strict welding quality requirements have led customers to have higher performance and functional requirements for spot welding machines and controllers. In the welding process, when the welding control is basically unchanged, the welding parameters can affect the welding quality.
Friends who have used resistance welding equipment or other resistance welding equipment for welding production know that if the parameters have been set to values, the welding quality is very good at the beginning of welding, but after a period of time, the welding quality will change. This is because the welding principle of resistance welding equipment and the physical and chemical properties of the spot welding head will cause dynamic changes in the welding parameters. That's why it affects the welding quality.
