Robotic welding is used for resistance spot welding along with arc welding. Spot welding is a type of electric resistance welding where two metal sheet products are joined by the heat which is obtained through the resistance to the electric current. These mobile robots are used in automotive industry which involves a high level of production applications.

Electric resistance welding refers to a group of thermoelectric welding processes, such as spot and seam welding. The weld is made by conducting a strong current through the metal to heat up and, finally, melt the metal at a localized point (Figure 6.4). This point is predetermined by the design of the electrodes and/or the workpiece being welded. A force is always applied before, during, and after the application of current to confine the contact area at the weld interfaces and, in some applications, forge the workpieces.
Deposition of coatings of non-ferrous metals and alloys on a carbon steel substrate*
Published in Welding International, 2018
A combined filler, consisting of SV-08 GOST 2246-70 wire with a diameter of 1.8 mm, inserted through the brass tube L63 GOST 494-90 with an inner diameter of 2 mm and a wall thickness of 0.5 mm, was welded to a steel 45 shaft (GOST 1050-88) with a diameter of 50 mm. Perforations 8 mm wide with a depth of up to 50% of the tube diameter were produced in the tube, the width of the bands between the perforations was 5 mm. Electric resistance welding conditions were: welding current 13 kA, electrode force 1.7 kN and current pulse time 0.06s. The duration of the break between the pulses was 0.08 s and welding speed was 15 mm/s.

Tube-making process usually involve two types of tubes, i.e. seamless tubes and electric resistant welded tubes. Seamless tubes are straightaway manufactured from solid billet and hence doesn’t require any metal joining operation. Whereas, electric resistance welding tubes (ERWs) are manufactured by welding the flat sheets of metal along longitudinal direction. Thus, cross-section of ERW tubes have welded joint throughout its length. ERW tubes are primarily used in low- or medium-pressure application.

Tungsten-copper alloys (W-Cu) are used mainly in electrical and thermal fields of applications [1,2], such as electric resistance welding, electrical contacts, heat sinks, in electrodes for electrical discharge, machining and electrochemical machining, chip carriers, substrates, flanges, frames for semiconductor power devices or charge liners, and especially suitable for oil-well completion [3,4].
