ISO 17677-1:2019 pdf free.Resistance welding一Vocabulary
This document establishes a vocabulary of terms and definitions for resistance spot welding, projection welding and seam welding.
NOTE In addition to terms used in English and French, two of the three official ISO languages,this document gives the equivalent terms in German; these are published under the responsibility of the member body for Germany (DIN). However, only the terms and definitions given in the official languages can be considered as ISO terms and definitions.
resistance welding secondary circuit variant in which wel-ding current and electrode force (3.3.5) are applied to the workpieces by directly opposed electrodes (3.2.1) and only one weld is made by one welding operation
Note 1 to entry: See Figure 13 for typical arrangements.
resistance welding process producing a weld at the fay-ing surfaces (3.3.16) between overlapping parts by the heat obtained from resistance to the flow of welding current through the workpieces from the elec-trodes (3.2.1) serving to concen-trate the welding current and pressure at the weld area
resistance welding in which force is applied continuously and current is applied con-tinuously or intermittently to produce a linear weld, the workpieces being between two electrode wheels (3.2.5) or an electrode wheel and an electro-de bar
resistance welding in which the resulting welds are localized at predetermined points by projec-tions, embossments or intersec-tions, concentrating force and current by their geometry
Note 1 to entry: The projections are raised on, or formed from,one or more of the faying surfa-ces (3.3.16) and collapse during welding.
destructive test in which a resistance-welded lap joint is tested by applying a peel force which results in stresses mainly in the thickness direction of the weld
test in which a lap-welded spe-cimen is subjected to a tensile force with the aim of determi-ning the mechanical properties of the specimen
area through which current pas-ses from an electrode (3.2.1) to the workpiece, smaller than the electrode working face (3.2.6) and which varies during the welding operation.ISO 17677-1 pdf free download.
