“…It is important because differences in zinc layer thickness on RSW design parameters are still unclear. This paper continues previous research that successfully joined SECC-AF material with low carbon steel material [18]. This study aims to obtain the highest tensile shear strength test results from combining RSW process parameters to joining differences in the zinc layer thickness of galvanized steel.…”

This article present the optimization work describes out to joint the dissimilar galvanized steel of SECC-AF (JIS G 3313) and SGCC (JIS G 3302) material. A zinc coating on the surfaces of the galvanized steel sheets will decrease the weldability characteristic of the material. This study used dissimilar galvanised steel sheets to obtain the highest tensile shear strength from the specified resistance spot welding. This research used the Taguchi method with 4-variables and mixed-experimental levels. The mixed-experimental level, namely 2-experimental levels for the first variable and 3-experimental levels for other variables. The highest tensile shear strength was achieved in 5282.13 N. This condition is achieved at a squeezed time of 20 cycles, 27 kA-welding currents, welding time of 0.5 seconds, and holding time of 18 cycles. The S/N ratio analysis has shown the welding current had the most significant effect, followed by welding time, squeeze time, and holding time. The delta values of S/N ratio were 0.79, 0.64, 0.26 and 0.07, respectively. The ANOVA analysis has shown that the P-value of welding current and welding time is 0.006 (0.6%) and 0.015 (1.5%), respectively. This result is expected for optimizing resistance spot welding quality in other materials or significant aspects.

“…These characteristics can be used to analyze other response data, such as tensile-shear strength [18], building strength [27], welding strength [28], corrosion resistance [29], tenacity of yarn [30], and fuel consumption. The S/N ratio for each L18 experiment has been calculated and listed in Table 7.…”

This study discusses the implementation of redox reactions on the thickness test of the galvanized (zinc-coated) layer using the JIS-H-0401 standard to help Small and Medium Enterprises (SMEs) industries. Some of the finished products go through the galvanizing process in the metal processing industry. Quality constraints, especially related to the thickness of the galvanic (zinc-coated) layer, have become an object that is less controlled because of the limitations of the test equipment used. This research uses an experimental method applied to one of its products: a flat washer with SPCC material and a thickness of about 2.20 mm. SPCC - SD material is classified as low carbon steel based on its carbon content. 5-unit flat washers were identified with sample codes A, B, C, D, and E. Flat washers have an internal diameter of 22.65 - 22.7 mm. In comparison, the outer diameter is between 43.75 - 43.80. The redox reaction process uses HCl (hydrochloric acid) with a concentration of 1 M, which is diluted with water (H2O). The zinc thickness test results show that the flat washer has an average thickness of 10.52 microns with a minimum and maximum thickness variation of 10.66 -10.72 microns.

“…Damage in SF flange often occurs at the location of Heat Affected Zone (HAZ). A HAZ is a part of the base metal located adjacent to the weld metal that undergoes a thermal cycle of heating and cooling rapidly during the welding process [1]. The HAZ is the most critical area of the welded joint.…”

This article discussed the design of dies and punched using SUS 316 material for seasoning funnel (SF) applications in the food industry. Cracks in the welding zone in the seasoning funnel (SF) result in leakage of seasonings and result in product mass, which is one of the main parameters in the food industry and a minimum. The damage location on the SF is identical, on the sides of the SF around the bolt holes. The movement of the spice powder, which rotates at high speed, produces a centrifugal force and is then transferred through the SF. The metal structure is becoming increasingly coarser in the area adjacent to the weld melting line. An additional punch with a knocking arm delivers to the SF to expedite the transfer. The knocking arm caused the SF fracture on the SF. SUS 316 sheet metal material for SF without welding is thought to reduce weld damage and speed up the procurement process. The input design for attempting to make dies has been correctly selected as SUS 316 material thickness of 1.0 mm. The two main processes required to form SF from sheet metal were blanking and bending. The SKD-11 material was selected carefully for the main components of the dies and punch. Supporting components such as shank, shaft, top plate, and bottom plate are determined using St 60 material. St 37 material determines the stripper, punch holder, and stopper components. Based on theoretical calculations, the blanking force should be about 225.5 kN. To minimize the burr in the blanking process, dies and punch allowances of 0.1 mm were chosen. The minimum required bending force calculation was 39 kN. A material factor springback value of 0.98 was selected correctly to achieve the desired bending angle. The simultaneous blanking and bending processes necessitated using a 72.96-tonne power press machine.
