Money collection presents particular problems in terms of effective vehicle routing. Planning the collection or distribution of money for ATMs or parking meters gives rise to two problems: while the total collecting time should be minimized, tours on successive days should be different to prevent robberies. The combination of these two problems is named as the Dissimilar Routing Problem. When t...

This study evaluates the macrostructure, microstructure, hardness, and tensile strength in dissimilar metal welding applied to bus body construction. The process involved joining hollow stainless steel galvanized at dimensions of 80 x 40 3.2 mm through Gas Metal Arc Welding (GMAW). current was varied 90, 100, 110 A while ER70S-6 electrodes with diameters 0.8 1.0 were used. results showed that e...

Dissimilar Metal Welds are required in high temperature sections of boiler reheater and superheater tubing to join low alloy steel tubing to the finishing stainless tubing. The intrinsic difference in the coefficients of expansion cause high stresses to develop at the relatively weak ferritic/weld interface. The power generation industry began to experience failures of type 309 stainless steel ...

Studies on dissimilar metal welding and mechanical fastening using metallic glasses in Utsunomiya University have been introduced. Metallic glass ribbons placed between the two plates become supercooled liquid with low viscosity by resistance promote supercooling at nuggets. As a consequence, residual stress boundary formation of brittle intermetallic compounds are suppressed, resulting excelle...

Aluminum of cylindrical profile (of diameter 1–4 mm) was trailed by laser metal wire deposition for potential riveting applications. The rivet built onto a Ti6Al4V substrate through hole in an AA6061 sheet. feature postprocessed high-frequency washing technique to obtain the desired finish. Parameter optimization has allowed increased productivity almost seven times while achieving required wet...

Time-of-flight neutron diffraction, contour method, and surface hole drilling residual stress measurements were conducted at Los Alamos National Lab (LANL) on a lab sized plate specimen (P4) from Phase 1 of the joint U.S. Nuclear Regulatory Commission and Electric Power Research Institute Weld Residual Stress (NRC/EPRI WRS) program. The specimen was fabricated from a 304L stainless steel plate ...
