This paper presents an experimental study on the resistance spot welding of SPA-H weathering steel sheets used in side wall and roof application of rail vehicle bodies. A timer and current controlled resistance spot welding machine having 120 kVA capacity and a pneumatic application mechanism with a single lever were used to prepare the specimens. Welding periods were chosen as 10, 15, 20, 25, and 30 periods (1 period = 0.02 s) and also welding currents were increased from 6 kA up to 11 kA by rises of 0.5 kA. The electrode force was kept constant at 4 kN. The prepared welding specimens were exposed to tensile-shear test and the obtained results were supported by diagrams and, finally, appropriate welding parameters were advised to the users.

“…In most cases, good spot-welding practice requires three parameters that have to be controlled, namely, current, time, and electrode force [8]. A common problem faced by manufacturer is the control of the process input parameters to obtain a well welded joint with required strength.…”

This paper presents an experimental study on resistance spot welding of SPA-H weathering steel sheets used in side wall and roof application of rail vehicle bodies. SPA-H steel sheets having 2.3 mm thicknesses were joined by using resistance spot welding as lap joint. A timer and current controlled resistance spot welding machine having 120 kVA capacity and a pneumatic application mechanism with a single lever was used to prepare the specimens. Welding periods were chosen as 10, 15, 20, 25, and 30 periods (1 period = 0.02 s) and also welding currents were increased from 6 kA up to 11 kA by rise of 0.5 kA. The electrode force was kept constant at 4 kN. The prepared welding specimens were exposed to tensile-peel test and the obtained results were supported by diagrams and, finally, appropriate welding current and time were advised to the users.

The Effect of Nugget Sizes on Mechanical Properties in Resistance Spot Welding of S235JR(Cu) Steel Sheets Used in Railway Vehicles

This paper presents an experimental study on the resistance spot welding of S235JR(Cu) steel sheets used in side walls and roofs of rail vehicle bodies. A timer and current controlled resistance spot welding machine having 120 kVA capacity and a pneumatic application mechanism with a single lever were used to prepare the specimens. Welding duration was chosen to be 5, 10, 15, 20, 25 and 30 periods (1 period = 0.02 s) and also welding currents were increased from 6 kA up to 14 kA in steps of 0.5 kA. The electrode force was kept constant at 6 kN. The obtained welding joints were exposed to tensile peel and tensile shear tests and their nugget sizes were measured by means of an optical microscope. The effect of nugget sizes on tensile peel strength and tensile-shear strength was determined using weld lobe diagrams. Based on this data the optimum welding currents and times were advised.
