“…Primary solidification will be ferrite if the chromium and nickel ratio is in the range of 1.5 to 2.0. If the nickel and chromium ratio is more than 2.0, the solidification phase will be completely ferrite which is exhibited by duplex stainless steel [61]. Duplex stainless steel exhibits high chances of cracking to indeterminate alloys which have austenite or austenite/ferrite solidification [4].…”

The current study investigates the effect of processing parameters Advance High Strength Stainless steel (AHSS) in terms of weld geometry by using the Pulse Wave (PW) mode of the fibre laser. The mechanical characteristics and microstructure are discussed and studied based on the literature. This study conducted an extensive literature review and highlighted various types of steel important for automotive applications. After that, laser welding of steel and the corresponding effect of parameters and their effect on weld geometry are discussed. It can be concluded that the variation of laser welding parameters can cause high thermal distortion and greatly affect the joint's mechanical performance. Hence, an optimum parameter value should be investigated to obtain a strong joint. This study also highlighted several avenues that researchers in future must explore.

“…In conventional general ultrasonic welding, the vibrations applied to the parts to be welded are linear vibrations in only one direction. However, it has been shown that ultrasonic welding can be applied using vibrations that apply twodimensional stress [7][8][9][10][11][12][13][14].…”

The authors have proposed a method of ultrasonic welding using planar vibration composed of longitudinal and torsional vibrations, and obtained higher tensile shear strength in a shorter time than by ultrasonic welding using conventional linear vibration. However, the cross tensile strength was not examined. And, the comparison of tensile shear strength and cross tensile strength in which the size, etc. of the weld samples was unified, and the tensile shear strength in changing the tensile direction and cross tensile strength in changing the peel direction for the vibration direction of the welding tip which applies ultrasonic vibration to weld samples have not been clarified. We performed ultrasonic welding using planar and linear vibrations with a change in weld time when the vibration direction of the tip of the welding tip applied to weld samples was changed. As a result, high tensile shear strength and cross tensile strength were obtained in a short time by ultrasonic welding using planar vibration. It was also clarified that there was almost no effect of the vibration direction of the welding tip on the tensile and peel directions.

“…11) Ultrasonic welding is a less damaging method for welding dissimilar metals and results in less deformation than laser welding or electron-beam welding. 12,13) However, conventional ultrasonic welding uses vibrations with a onedimensional linear locus. 14) This method suffers from the problem that, since the vibration energy is small, the weld strength is low and variable depending on the installation direction of the welding sample.…”

Conventional ultrasonic welding uses vibrations with a one-dimensional linear locus. Because the vibration energy is small, this method suffers from the drawbacks that the weld strength is low and variable depending on the installation direction of the welding sample. Our previous studies have revealed that the weld strength can be improved by using vibrations with a two-dimensional planar locus. However, the question of whether welding using planar vibration could be achieved in a short weld time and the relationship between the installation direction of the welding sample and the weld strength remained unclear. Therefore, these issues were addressed by the investigation described in this paper. Consequently, we demonstrated that welding using planar vibration reaches a high strength in a shorter weld time than conventional linear vibration and that stable welding can be achieved independently of the installation direction of the welding sample.
