6 FAQs about [Appearance of energy storage weldment]
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.
How does welding energy affect electrical contact resistance and tensile force?
Further increasing the welding energy leads to electrode sticking and significant expulsion of bulk material , , , . Fig. 6. Electrical contact resistance and ultimate tensile force as function of welding energy.
Does high-speed imaging improve weld appearance in high-power fiber laser welding?
To examine the mechanisms of improving the weld appearance in detail, a high-speed imaging system was applied to observe the keyhole and melt flow and pool in high-power fiber laser welding. Finally, the mechanisms of the improvement of weld appearance were discussed. 2. Design of Experiments (DoE) Figure 1 shows the setup of experiments.
What are the conditions for K-TIG welding?
1. The necessary conditions for K-TIG welding are sufficient current and voltage as well as sufficient cooling of the torch. This ensures a high arc current density, makes the effect of electromagnetic contraction significant, and leads to the increase of arc energy.
Can high-power fiber laser welding produce heavy section structures?
Author to whom correspondence should be addressed. High-power fiber laser welding is an efficient and effective way to produce heavy section structures. However, there is a significant challenge in producing the welds with free of imperfections such as nail-head-shaped welds, spatters, and root sagging.
What happens if a weld ejects a spatter?
On the one hand, spatters falling on the specimen surface burn the surface material and create a poor surface appearance. On the other hand, ejection of spatters was accompanied by formation of underfill, undercuts, craters, and blowouts, which can severely reduce the mechanical properties of a weld [ 12 ].
