Numerical simulation of laser impact spot welding

Journal of Manufacturing Processes, 2018
Abstract Laser impact spot welding (LISW) is a relatively novel high-speed impact welding technology. It has obvious advantages in welding dissimilar metal foil plates which have a large difference in melting point. However, the bonding mechanism of laser impact spot welding and dynamic mechanical behavior during LISW are difficult to be revealed ...

Dynamics of space welding impact and corresponding safety welding study

Acta Astronautica, 2004
This study was undertaken in order to be sure that no hazard would exist from impingement of hot molten metal particle detachments upon an astronauts space suit during any future electron beam welding exercises or experiments. The conditions under which molten metal detachments might occur in a space welding environment were analyzed.

Impact modeling of the weld line of tailor-welded blank

Materials & Design, 2008
Finite element analyses of tailor-welded blank based on vehicle impact are performed to determine the effects of weld modeling techniques on simulation results. A novel welding model is put forward in this paper, including a simple representation of the weld geometry and material properties, which uses two-fold beams to simulate the behavior of the ...

The impact strength of butt welded vibration welds related to microstructure and welding history

Polymer Engineering & Science, 1989
Abstract A study has been made of vibration butt welds between plaques of polypropylene. The quality of the welds, as determined by impact tests, has been examined as a function of the welding variables: pressure and vibration amplitude.

Explosive and impact welding: technical review

Materials Technology, 2007
AbstractExplosive welding has proven to be an economical and technologically successful process. However, detailed understanding of the parameters involve in the process has only recently been developed and tailored through gas gun experiments. The use of welding processing domains, obtained from these gas gun studies, makes it possible to determine ...

Impact strength measurement of spot welds

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2001
The impact strength of spot welds is a very important quality index in the automotive industry. However, impact testing is not routinely performed for weld quality testing because of its complexity, cost and relatively low reliability and repeatability.
