“…Elements 1-3 make up an electrode device (ED). The electrode device (ED) is placed in the axis of the weld of a welded joint, fixed to mounting plate (5) by means a fixing load (q). After the capacitive energy accumulator (CEA) has been fully charged and with the power switch (K) being in the off-position, electric pulsed current flows through circuit elements 1-3 to 4.…”

“…The disc (3) is connected to the induction coil (4). Above the connection terminals there is a casing (5), which is also used for the positioning of the electrode device (ED) during electrodynamic treatment. The electrode device is connected to the source of electric pulsed current (SEPC) using terminals 6 and 7 located at the top of the housing (2).…”

“…The holder is used by the operator to move the tool. The plate is provided with the lighting of the EDT area (4), the electrode device (ED) (5) from SEPC to processed metal and two support (6), which, along with the electrode device provide the three-point support of the tool on the processed metal surface. The tool is provided with a transport cart (7) used for moving and setting the electrode device (ED) along a welded joint.…”

“…To optimise the model of the EDT regime it was necessary to develop a mathematic model of non-stationary electrophysical [5] and dynamic [6] processes determining the mechanism of the electrodynamic effect. The model is used for selecting EDT characteristics aimed to control the internal stresses of alloy AMg6.…”

“…A stringer (2) (resting on a rigid base) is located between a stamp (1) and a die (3). The stamp is rigidly connected with a disc (6) made of a non-ferromagnetic material, which, in turn, is the base of a flat induction coil (5). After starting a capacitor (C) discharge cycle using a contactor (K), repulsive electrodynamic force is generated between the induction coil and the disc.…”

The article discusses the electrodynamic treatment (EDT) of thin-walled welded structures and EDT equipment, presents results of mathematical modelling concerning the effect of EDT on stresses in welded sheets made of aluminium alloy AMg6 as well as discusses the effect of EDT on the plastic strain mechanism. In addition, the article presents tests results concerning the effect of EDT during the welding of ship structures made of AMg6 plates and discusses the role of EDT in bulge formation. In addition, the article discusses the application of EDT during the repair welding of aero-engine nacelles made of magnesium alloy ML10 and the effect of EDT on openings in an airplane wing stinger in relation to its service life.
