This research was conducted to investigate the effect of variations in tool rotation and surface roughness towards shear strength on the newly developed friction lap welding (FLW) for dissimilar joints between stainless steel (SS) 304 and Nylon 6 plates. Under constant welding traverse speed at 30 mm/min, the variation of tool rotation used were 1100 and 2200 rpm and surface roughness of 0.32; 1.25; and 1.88 μm initially obtained from different surface modification methods. The shear test was conducted at FLW dissimilar joint based on AWS D8.9-97 standard. The results showed that the shear stress increased along with the higher tool rotation and at the greater surface roughness. The highest shear strength value was found at the tool rotation of 2200 rpm and surface roughness of 1.88 μm with 9.447 MPa. The tool rotation may produce a higher heat input as well as an effect on the value of nylon hardness. On the other hand, rougher SS surfaces provide a larger area for the interfacial adhesive bond between nylon and metal; therefore, they can act as an interlocking site when the shear loading was applied. These phenomena were also confirmed by fracture morphology and microscopic image analysis.

The machinability information of Zr-based bulk metallic glasses (BMGs) are recently limited but essential to provide technological recommendation for the fabrication of the medical devices due to the material’s metastable nature. This study aims to investigate the material removal rate (MRR) and surface roughness under different current and pulse-on time of newly developed Ni- and Cu-free Zr-based BMG using sinking-electrical discharge machining (EDM). By using weightloss calculation, surface roughness test and scanning electron microscopy (SEM) observation on the workpiece after machining, both MRR and surface roughness were obtained to be increased up to 0.594 mm3/min and 5.50 μm, respectively, when the higher current was applied. On the other hand, the longer pulse-on time shifted the Ra into the higher value but lower the MRR value to only 0.183 mm3/min at 150 μs. Contrary, the surface hardness value was enhanced by both higher current and pulse-on time applied during machining indicating different level of structural change after high-temperature spark exposure on the BMG surface. These phenomena are strongly related to the surface evaporation which characterize the formation of crater and recast layer in various thicknesses and morphologies as well as the crystallization under the different discharge energy and exposure time.

In this study, Nylon 6 and SS AISI 304 were joined using friction lap welding (FLW) by filling the pre-hole in SS AISI 304 plate. The shear property and fracture morphology were analyzed using both experimental and numerical approaches. The pre-hole prepared SS AISI 304 plate was placed at the top of the Nylon 6 plate and constantly clamped together during the FLW process under traverse speeds of 10, 30, 50 mm/min with hole row distances of 20 and 24 mm. Afterward, the shear strength test was conducted using the MTS based on AWS D8.9-97 standard. The macroscopic fracture surface images were also provided to confirm the shear test result. The heat input is strongly determined by the shear properties of the joint, where the higher traverse speed shifts the shear strength to the lower level. On the other hand, hole row distance indicates the distance between each row to the respective heat source; therefore, the closer distance induces higher shear strength. This heat input showed a remarkable effect on determining the shear strength of the FLW joint, along with the stress concentration generated around nylon pins during shear loading, as confirmed by the simulation results. These phenomena are further demonstrated by the fracture and peel surface of the FLW joint, where the joint formed by higher heat input showed a larger brittle fracture area at the pin and deeper cleavage because of material loss moving to SS plate top surface. The shear strength value was inversely proportional to ductility.

Proses pengelasan jika tidak diperhitungkan sebelumnya dapat mengakibatkan bahaya-bahaya yang tidak diinginkan bagi pekerja las, contohnya kebakaran, peledakan, keretakan, dan bahaya yang tidak kalah pentingnya adalah bahaya yang mengganggu alat pernapasan. Bahaya tersebut berasal dari asap dan radiasi sinar las. Meskipun demikian, pedoman untuk bekerja secara aman sesuai dengan prosedur kesehatan dan keselamatan kerja seringkali diabaikan, terutama oleh pekerja las di sektor informal dengan skala kecil. Oleh karena itu sangat wajar jika seringkali ditemukan tenaga kerja di bengkel pengelasan yang bekerja dengan tingkat keamanan yang sangat minim. Keadaan tersebut menyebabkan perlunya diadakan pelatihan guna meningkatkan pemahaman bahaya proses pengelasan serta keselamatan dan kesehatan pekerja las di sektor informal.
