Comparison between medium frequency spot welder and common resistance welder
Welding faces the challenge of high strength steel plates.Welding process of galvanized steel sheet and multilayer steel plate.Application of aluminum alloy sheet material.The widespread use of automatic flexible production line for welding robot.Continuously reduce energy costs, quality costs, and maintenance costs.
Long term problems in general resistance welding:Instability of welding quality.Spatter during welding.Lack of effective data monitoring for welding quality.Excessive wear of electrodes.The power factor is low, and a large number of capacitor compensation cabinets are added to improve the power factor.
Characteristics of general resistance welding:1, due to low frequency, frequency (50HZ), the quality of welding instability.2, more spatter during welding.3, the welding quality is lack of effective data monitoring.4, excessive wear of electrodes.5, the power factor is low, and a large number of capacitor compensation cabinets are added to improve the power factor.6, excessive energy costs.7, AC welding two times, the impact of strong magnetic field on human health.Welding characteristics of medium frequency electric welding machine:1 、 adopting digital intermediate frequency welding controller, the quality of welding can be effectively controlled.2, welding process greatly reduces spatter, improve welding quality and purify welding environment.3, the integration of welding welding machine, suspension collocation.4 、 powerful welding function, providing welding quality analysis data and monitoring5 、 integrated modular design, welding control system performance is stable, high reliability, low welding failure rate.6, the use of electrode pressure reduction, greatly improve the electrode life.7 、 adopting three-phase balanced load and intermediate frequency welding technology, no need to add capacitance compensation cabinet.8, digital intermediate frequency welding, energy saving more than 30%, greatly reducing energy costs.9. Accurate control of welding parameters (1MS) for seamless welding of steel sheet / variable thickness steel plate / high strength steel plate / aluminum alloy.10, super small volume and weight of the welding transformer, meet the application and integration of the welding robot.11, HMI control, user-friendly operation programming software, convenient and quick.
