Magnetic Pulse Welding
Magnetic pulse welding is a contactless process where electromagnetic forces accelerate tubular parts and join them by cold welding to create a form-fit joint. It requires precise control of speed and distance.
Physicochemical Mechanism of Action
Electromagnetic fields accelerate the parts, which then join positively via cold welding. The rapid movement and cool contact ensure a high welding speed.
Metallurgical Relevance & Risks in Welding
Incorrect speed or distance can lead to uneven welding, porosity, or even loss of the positive connection. This increases the risk of cracks and reduces mechanical strength.
Workshop Practice & Operating Instructions
Make sure the parts are at a fixed distance from each other and the acceleration speed is precisely set. The recommended speed is typically 50-100 m/s. Continuously monitor the process and correct the settings as needed.
