摘要
OTC(DAIHEN Corporation)公司新研发的CBT焊接控制法实现了GMA焊接的低飞溅和低热输入,特别是针对薄板,进一步提高了薄板的焊接性能,这对早期的传统焊接控制技术来说是很难实现的。通过调节负极占空比,交流CBT控制法能够实现改变焊接过程中的熔深和熔敷量,有效避免了薄板焊接中的烧穿和降低热变形问题。新开发的反抽起弧控制确保了起弧的成功率并有效拟制飞溅的发生。
The newly developed ＂Controlled Bridge transfer（CBT）＂ welding control method further achieved the ideal Gas Metal Arc （GMA） welding evolution of low spatter performance and low heat input,especially improved the welding quality of thin sheet material. Previously,it was very difficult to achieve by conventional welding control technology.By adjusting the polarity ratio （EN ratio） between electrode positive（EP） and electrode negative（EN）, AC-CBT method made it possible to freely change the depth of penetration and the metal deposition during welding,and efficiently avoid burning through and heat distortion of thin sheet welding.The new Retract Start （RS） control ensures proper arc starts and spatter reduction at the start of the arc.
