Dynamic Feed (Wire Oscillation)在TIG过程中只是一个示例。与其他电弧焊接过程相比,通常归因于常规TIG的一个缺点是生产率低。
在TIG系统中已经实施了前进和向后的振荡运动,以管理此缺点并更好地处理硬润湿材料(例如,NI-CR合金)。欧洲杯足球竞彩这种实施在行业中受到了广泛的欢迎,并在科学界引起了极大的兴趣。
The technique may also provide a further benefit of reducing porosity. In terms of observation and stability evaluation of the metal fusion and transfer, arc behavior and weld pool behavior, high-speed filming has been a powerful tool in the study and development of such techniques. The main purposes of such studies are the scientific investigation into the influence of parameters over the resulting physical phenomena and the development of parameterization for different welding conditions (position of wire feeding, torch geometry, wire dynamics).

In terms ofMIG/MAG焊接, new technologies are designed to support the development of adaptive control methods, innovative current waveforms and mechanization techniques to improve arc stability, metal transfer regularity, process reliability and expansion of the application range.
The rotary arc and the pulsed arc mode are examples of this, both of which show promise in achieving outstanding results for cladding and thick-walled narrow gap joints. In such scenarios, high-speed filming is applied for metal transfer phenomena observation, arc movement patterns and respective influences over the weld pool, arc geometry and generation of the weld bead. Furthermore, to evaluate consumables and peripherals (such as wire-electrodes, contact tips and wire feeders), high-speed filming has been applied.

A CMOS, 1-megapixel array size color camera was applied in the videos above with 105 mm and 180 mm macro lenses. A Data Acquisition System was used to adjust acquisition rates in synchronization with electric welding data monitoring.
Cavilux HF已深入应用这些调查和发展。可以使用激光照明系统对产生的高速图像的电弧强度进行精确调节。这使得可以选择和隔离特定的焊接过程功能(电线,电弧,液滴,池等)。
