Effects of Reactive Interlayers in Magnetic Pulse Welding

, 2018
Surface coatings affect the joint formation in magnetic pulse welding processes (MPW). Two types of coatings were identified in former studies. Anodized layers, for instance, are detrimental for the weld formation if they are not removed before or during welding. Contrastingly, a nickel layer on a steel parent part was found to be advantageous since it

Optimization of electromagnetic steel lamination laser spot welding process parameters using response surface methodology

Scientific Reports
Electrical steel is a critical material for key components such as electric motors and transformers. Conventional continuous welding, characterized by high heat input and a wide heat-affected zone (HAZ), often leads to magnetic degradation.

Development of Multi-Part Field-Shapers for Magnetic Pulse Welding Using Nanostructured Cu-Nb Composite

Journal of Manufacturing and Materials Processing
Magnetic pulse welding (MPW) employs a strong pulsed magnetic field to accelerate parts against each other, thus forming an impact joint. Single-turn tool coils and field-shapers (FSs) used in MPW operate under the most demanding conditions, such as ...
