This paper presents how to design and test vibration induced truck chassis brackets via magnetic impelled arc butt welding. Magnetic impelled arc butt welding is a technique which reduces the manufacturing costs, flexible in design and improved durability when compared to other welding techniques. Design of magnetic impelled arc butt welded parts using Finite element (FE) techniques and testing the parts with Road Load Data (RLD) tests is explained. Natural frequencies of the parts are calculated, and then, frequency response FE analysis has been performed for worst case conditions. Correlation of the design has been performed via real-life tests with RLD data. It has been shown that magnetic impelled arc butt welding can be applied for other parts working under vibration load.
