An Overview of Stud Welding Processes: The best joining method for your project depends on the desired material, the stud diameter, and the sheet metal thickness. In this article, we provide a concise overview from bsk + BTV GmbH.
For every industrial application
Component geometry and material requirements play a decisive role in selecting the appropriate process. Bolt Welding Technology bsk + BTV GmbH provides an overview of all three established bolt welding processes and supplies the appropriate equipment from a single source. To ensure that automated and manual processes in your production are monitored in accordance with standards, all welds must meet strict criteria. You can find detailed information on all regulatory requirements on our information page regarding DIN standards for stud welding. The exact guidelines for ensuring reproducible quality are also specified in the official DVS Technical Bulletin 0901, available from DVS Media.
What are the main differences between stud welding methods using tip ignition and stroke ignition?
Peak ignition is a capacitor discharge (CD) process. The energy is discharged abruptly over 1 to 3 milliseconds, leaving the back side of thin sheets virtually mark-free. The classic drawn arc (ARC) process uses a reciprocating mechanism and longer welding times (100 to 2,000 ms), making it ideal for large diameters and thick, robust components. We would be happy to determine which system is the best solution for your production during a personalized consultation right at your facility.
An Overview of Stud Welding Methods: When Should You Use Short-Duration Ignition, Inert Gas, or a Ceramic Ring?
Short-pulse ignition, with a welding time of 5 to 100 milliseconds, falls right in between and is often used in industrial automation. For large bolt diameters exceeding 12 mm, a ceramic ring protects and shapes the molten pool on the component. Inert gas is a clean alternative for smaller diameters, particularly in robot-guided processes or automated production lines.
An Overview of Stud Welding Methods: What Are the Differences Between Contact Welding, Gap Welding, and Penetration Welding?
In the gap welding process, the stud is accelerated before welding, which is ideal for aluminum, where alternating current breaks down the oxide layer. The contact method is suitable for coated sheet metal. In the through-welding technique, the stud is joined to the component through a cover plate, which requires special ceramic rings. In this way, our systems guarantee a reliable joint for every application.
