A Double Seam Profile Tracking Automation Method for Cylindrical Welding Technique

Abstract

This paper introduces a new method related to the joining of the metal pieces using cylindrical welding technique by determining double seam profile tracking. With the help of this method, solid and stabile welding quality is achieved on the applied materials. For this aim, a welding oscillator is implemented. The cylindrical welding operation is carried out properly on the applied metal pieces with the aid of two laser sensors, which find and eliminate eventual joining faults. Firstly, the position of the welding region is determined using the first laser sensor. After the welding process is done, a second laser sensor is used to check for the detection and elimination of the possible welding faults, so that a high quality welds can be performed. With the suggested cylindrical welding technique, only one special welding is required that makes the whole process more environment and budget friendly. Furthermore, the required energy and time for the welding operation are reduced significantly compared to the conventional manual welding. Moreover, consumption of hazardous gases, which are needed for protective shielding during the welding process such as carbon dioxide (CO2), electric energy and electrode mass, were reduced greatly due to the elimination of the unnecessary welding operations.
