TL;DR: In this paper, a non-destructive determination of the quality of a weld seam is performed by using a measuring device, an analyzing unit, and a welding device, which are connected by a seam produced by a welding operation and measured a surface temperature of the weld seam and surface temperatures of areas of the first and second components adjacent to the seam.
Abstract: A process for the non-destructive determination of the quality of a weld seam, the process steps comprising: providing a first and a second component; connecting the first and second components by a weld seam produced by a welding operation; and measuring a surface temperature of the weld seam and surface temperatures of areas of the first and second components adjacent to the weld seam that were heated by the welding operation. A system for carrying out the process for the non-destructive determination of the quality of a weld seam, the system comprising: a measuring device, an analyzing unit, and a welding device.

TL;DR: In this article, a new friction stir welding process for high strength and high melting point materials such as steel and titanium, called "electrically enhanced friction stir welding process (EHFSW)" has been suggested and analyzed using finite element modelling.
Abstract: Conventional friction stir welding (FSW) of high strength and high melting point materials, such as steel and titanium, has the disadvantages of a serious tool wear problem and slow welding speed. A new friction stir welding process for such materials called 'electrically enhanced friction stir welding process (EHFSW)' has been suggested and analysed using finite element modelling. The basic idea of EHFSW is that electric current passes from the welding tool into the workpiece through the contact area in the welding region. Thus it results in more localised heating while welding is in progress and is not simply a preheating process. The temperature distribution in the workpiece during the pin plunge stage and the welding stage of the EHFSW process has been determined. The results show that EHFSW can reduce the plunge force significantly with the help of localised electrical heating during the pin plunge stage, which may imply lower tool wear when compared with conventional FSW. At the same time, i...

TL;DR: In this paper, the authors introduced a way of ultrasonic generation by exciting electric arc and found that the effect of grain refinement was found in the Ti-6Al-4V welding joint.
Abstract: Traditional ultrasonic generation ways can not be applied in welding process effectively. This letter introduced a way of ultrasonic generation by exciting electric arc. When electric arc is excited by high frequency current, it generates ultrasonic. Experiments showed that welding arc had broad band response characteristic and the main factor of ultrasonic intensity was the exciting current. With the ultrasonic treatment generated by exciting arc, effect of grain refinement was found in the Ti–6Al–4V welding joint. This method of ultrasonic generation is believed to have an extensive use in material processing.
