Interaction of impact-compressed gas in the welding gap with the welded surfaces in explosive welding

Welding International, 2017
AbstractIt is shown that in explosive welding in conditions preventing the formation of a cumulative jet, the cleaning and activation of the welded surfaces take place ahead of the contact point by the plasma flows. Impact plasma forms in the welding gap during the hypersonic discharge of the high-temperature impact-compressed gas at its boundary with ...

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 of the Switching Frequency on the Welding Current of a Spot-Welding System

IEEE Transactions on Industrial Electronics, 2017
This paper deals with an analysis of a middle-frequency resistance spot-welding (RSW) system with a dc welding current controlled by a pulsewidth modulated inverter, which supplies a welding transformer with a full-wave rectifier mounted at the secondary.

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.
