1. Introduction. Cold Metal Transfer (CMT) is an advanced technology used in welding, which was first put forward by Fronius in 2002. Because of its advantages such as no spatter and low heat input [1], [2], [3], it is preferable in thin sheet welding.At present, CMT has been applied in welding single-pass 2-mm-thick aluminium [4] and multi-pass …
An in-process method for controlling welding distortion in fillet welds is developed. It particularly reduces angular distortion by performing reverse-side Tungsten inert gas (TIG) heating of the weld line at a fixed distance ahead of metal inert gas (MIG) welding during the weld process.

The amount of energy delivering into the welding system follows the commonly used energy generation equation: (1) Q = ∫ t 1 t 2 I 2 (t) R (t) d t, where Q denotes the energy delivered into the welding system in Joule, t 1 and t 2 respectively denote the beginning and terminating time of the welding action, I(t) is the welding current, R(t) is ...
The energy input into the process zone is higher for welding a stack of foils compared to welding a sheet of copper when using the same process parameters. 3. Part-to-part gaps can be detected because the thermal resistance between the foil stack and the arrester tab is increased by the gap, resulting in an amplification of the detected signal ...
Energy consumption and thermal efficiency analysis of arc welding processes. In arc welding processes, an intense electrical arc is used as the heat source to melt metallic materials locally, which is joined upon solidification. The energy consumption is affected by welding parameters especially welding current, welding …
Example Use Cases. This section provides three example use cases to illustrate how DOE tools can be used for storage valuations for three use-case families described earlier in this report: 1) facilitating an evolving grid; 2) critical services; and 3) facility flexibility, efficiency, and value enhancement.
The process parameters directly affect the quality and performance of laser welding (LW) by shaping the molten pool appearance. However, with the increase in the dimensions of process parameters and the number of samples, the relationship between process parameters and molten pool often exhibits high levels of uncertainty and …
Our analysis shows that substantial energy loss can occur during welding due to the flexural vibration of the Cu coupon, especially when the overhang (the upper part of the Cu coupon extended from the anvil) of the Cu coupon resonates at or close to the welding frequency (about 20 kHz), degrading the weld quality of battery tabs. This study ...
A solar energy accumulator was used as the latent heat storage unit. It can be concluded that an indirect solar cabinet dryer with paraffin wax as an energy storage material is an effective design for creating more favorable conditions for the drying process compared to an indirect solar cabinet dryer without energy storage.

Electron beam welding (EBW) is widely used to connect thin-walled high-temperature alloy structures in aeroengines. However, the residual stress and deformation caused by the high-temperature gradients generated during welding would affect the rigidity, dimensional stability, and fatigue resistance of the welded structures. The study reported here used a …

Fig. 4 (a) explains how battery cells with hard casing, i.e., cylindrical or prismatic cells, are resistance spot welded with parallel weld electrodes. Apart from the desired current I weld, a stray current I stray flows. Therefore, the power source has to provide a higher current I electrode and electrode sticking may occur. In Fig. 4 (b), spot …
