Finite Element Analysis of a Welding Transformer
نویسنده
چکیده
The study introduces the detailed sequence of operations necessary to determine the selfand mutual inductances of power transformers from numerically simulated open-circuit and bucking experiments. Parameters of a welding style transformer are compared to those of a normal step-down transformer of equivalent ratings. The investigation identifies the different patterns of magnetic flux circulation when the two transformers operate with rated load. Implications of the high reactance of welding transformers on the consumption of reactive power and power factor are analyzed.

Power Auto-transformer Mechanical Faults Diagnosis Using Finite Element based FRA
Frequency response analysis (FRA) is a sensitive method established for testing the mechanical integrity of transformers. However, interpretation of FRA signature still needs expert opinions and there is no FRA interpretation code generally accepted. Various mechanical faults with different extents on power transformers are required to aid FRA interpretation. To address this challenge, in...

Although a few models have been proposed for 3D simulation of different welding processes, 2D models are still more effective in design goals, thus more popular due to the short-time analysis. In this research, replacing "time" by the "third dimension of place", the gas tungsten arc welding process was simulated by the finite element method in two dimensions and in a short time with acceptable ...

In the present research, the effects of spot-welding process parameters on the nugget diameter and electrode penetration depth of spot-welded joints were investigated. To achieve this, a spot-welded joint of three-thin sheet low carbon steels (same thicknesses of 0.8 mm) was simulated as an electerical-thermal-mechanical coupling of 3D finite element model. After validating the finite element s...
