研制成功了一种恒流带短路补偿的一元化调节新型MIG焊机,指出了新型电源设计的技术关键和解决办法,给出了引弧短路补偿器、一元化调节理论方程和部分一元化调节最佳规范曲线。通过工艺试验结果对比,进一步肯定了“等速送丝——恒流电源”调节系统焊接的优点,为这种新型工艺的推广使用提供了可靠的依据。 A new type of MIG welding machine with constant current compensation and short circuit compensation was successfully developed. The key technology and solution to the new power supply design were pointed out. The arc-ignition short-circuit compensator, unified regulation theory equation and partial optimization regulation curve. Through the comparison of process test results, we further affirm the advantages of “constant speed wire feeding - constant current power supply” regulation system welding, which provides a reliable basis for the popularization and application of this new technology.
