Electron-beam welding (EBW) is a fusion welding process in which a beam of high-velocity electrons is applied to two materials to be joined. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact.
Radio-frequency welding, also known as dielectric welding and high-frequency welding, is a plastic welding process that utilizes high-frequency electric fields to induce heating and melting of thermoplastic base materials. [1] The electric field is applied by a pair of electrodes after the parts being joined are clamped together.
Typically the sheets are in the 0.5 to 3 mm (0.020 to 0.118 in) thickness range. Forcing a large current through the spot will melt the metal and form the weld. The attractive feature of spot welding is that a large amount of energy can be delivered to the spot in a very short time (approximately 10–100 milliseconds). [2]
Some applications and patents connected with friction welding dates back to the turn of the 20th century, [3] and rotary friction welding is the oldest of the methods. [4] W. Richter patented the method of linear friction welding (LFW) process in 1924 [ 5 ] in England and 1929 [ 5 ] in the Weimar Republic .

Is responsible for the Collaboration Projects of EWF and has coordinated more than 20 large projects involving organisations from all EU.
The Canadian Welding Bureau, through CSA Standards W47.1, [3] W47.2 [4] and W186, [5] specifies both a WPS and a Welding Procedure Data Sheet (WPDS) to provide direction to the welding supervisor, welders and welding operators. The WPS provides general information on the welding process and material grouping being welded, while the WPDS ...
