Portable and intelligent stud welding inverter for automotive and sheet metal fabrication

Abstract

This paper introduces a new, portable and intelligent inverter for stud welding in automotive rework and robot backup, and for general sheet metal fabrication applications. The new portable inverter combines the virtues of precision and simplicity. High repeatability, accuracy and arc stability are ensured with digital signal parallel processing and Dual LoopTM fast arc regulation technology, designed for stud welding. High surge current is provided with unique Parallel SiliconTM technology for advanced high strength steel and to overcome adverse surface coating. A user-friendly interface called Stud ExpertTM introduces a new programming methodology based on application conditions instead of machine settings such as time and current. Procedures can be memorized and recalled by the use of pre-sets. Quality assurance is embedded inside the welder to determine weld quality and to monitor production data. © 2007 Springer-Verlag Berlin Heidelberg.
