6 FAQs about [Stretched arc energy storage welding]
How arc welding works?
For arc welding, the production efficiency, weld formation, and quality control ultimately depend on the welding heat input that can be achieved by controlling the magnitude and distribution of the arc energy density. 1. The conventional activating fluxes include a metallic simple substance activator, oxide activator, and halide activator.
Can modified tungsten inert gas welding improve arc energy density?
Through collecting, sorting, and analysing the research data of tungsten inert gas (TIG) welding in China and abroad, the modified TIG welding and ways to realise the improvement of the arc energy density are summarised. Based on the existing literature, two methods have been employed to improve the arc energy density.
How to improve the energy density of TIG welding arc?
Based on this, many methods to improve the energy density of TIG welding arc are devised. These include activating flux TIG (A-TIG), twin-electrode TIG (T-TIG), keyhole TIG (K-TIG), high-frequency pulse TIG (H-TIG), ultrasonic-TIG hybrid arc (U-TIG), magnetic field control TIG (M-TIG), and hollow tungsten central negative pressure arc welding.
What is the relationship between arc voltage and weld properties?
As a consequence of the relationship between welding current and arc voltage, weld properties and geometry can be predicted (Shoeb et al. 2013): welding with a high voltage produces a very wide bead with possible undercuts and a concave shape, and welding with too low a voltage produces a low-quality weld bead.
What are some examples of arc welding?
This article reviews the present status in this aspect. A few typical examples such as external magnetic field-assisted gas metal arc welding, ultrasonic vibration-assisted gas tungsten/metal arc welding, and ultrasonic-assisted plasma arc welding are introduced to demonstrate their system, principle and effectiveness.
How efficient is controlled short arc welding?
