welding current
21resistance welding — welding utilizing pressure and heat that is generated in the pieces to be welded by resistance to an electric current. [1910 15] * * * …
22Gas metal arc welding — RMD redirects here. RMD may also refer to IRA Required Minimum Distributions. Gas metal arc welding …
23Arc welding — uses a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point. They can use either direct (DC) or alternating (AC) current, and consumable or non consumable electrodes.… …
24Electric resistance welding — (ERW) refers to a group of welding processes such as spot and seam welding that produce coalescence of faying surfaces where heat to form the weld is generated by the electical reistance of material vs the time and the force used to hold the… …
25Electron beam welding — (EBW) is a fusion welding process in which a beam of high velocity electrons is applied to the materials being joined. The workpieces melt as the kinetic energy of the electrons is transformed into heat upon impact, and the filler metal, if used …
26Shot welding — is a specific type of spot welding used to join two pieces of metal together. This is accomplished by clamping the two pieces together and then passing a large electric current through them for a short period of time. Assuming the right amount of …
27Induction welding — is a form of welding that uses electromagnetic induction to heat the workpiece. The welding apparatus contains an induction coil that is energised with a radio frequency electric current. This generates a high frequency electromagnetic field that …
28Stud welding — is a form of spot welding where a bolt or specially formed nut is welded onto another metal part. The bolts may be automatically fed into the spot welder. Weld nuts generally have a flange with small nubs that melt to form the weld. Studs have a… …
29resistance welding — noun : a form of electric pressure welding in which the necessary heat is produced by a flow of current through the parts to be welded and sufficient pressure to make the weld is applied simultaneously with the flow of current compare butt… …
30Magnetic pulse welding — (MPW) is a welding process that uses magnetic forces to drive two workpieces together and weld them together. The welding mechanism is most similar to that in explosion welding.[1] Process A very high AC current (the primary current ) is passed… …
