“…In order to improve the joining performance of the pressure welding process, a lot of studies were conducted at elevated temperature. 5,9,13 A survey was performed by McQueen 14 to review how the fundamental knowledge developed in hot working applied to various non-fusion welding methods. However, complex heating facilities were required in the warm pressure welding process.…”

Efficient joining technique of thin metal sheets is required in the mass production of fuel cell bipolar plates, micro-reactor carriers and so on. Solid-state bonding (pressure welding) process is found to be a promising solution, because the process is efficient and large area welds can be achieved in one welding/bonding procedure. However, successful bonding cannot be achieved by conventional pressure welding process for some materials (e.g. stainless steel). In order to realize successful bonding and improve the bond performance, an electrical-assisted solid-state welding process was proposed in the present study. Experimental setup was developed to investigate the joining process of stainless steel and brass sheets. The effects of electric current as well as process conditions (e.g. welding pressure, sheet thickness and temperature) on the bond strength were studied experimentally. The results indicate that the maximum bond strength of stainless steel improves from 24.4 to 33.2 MPa with the increase of current density from 6.7 to 20 A/mm2. Furthermore, an analytical model to predict the shear load force was established. In the model, different deforming behaviors of the contaminant layer and the virgin metal were discussed. Good agreement between the analytical and the experimental results was observed. Based on the model, the improvement of the weld strength in the electrical-assisted solid-state welding process was characterized theoretically, which also proves the feasibility of the process.

“…For multi-layered laminated composites, pressure-based joining comes into consideration. In the review article by H. J. McQueen, 1 the differences between pressure-based joining, diffusion bonding and friction joining are explained. In terms of production efficiency, rolling is an advantageous method, which permits the pressure-based joining of two or more dissimilar materials.…”

The fabrication of laminated steel composites by hot rolling is described. Composite sandwiches were made from martensitic stainless tool steel with an increased nitrogen content and from standard AISI 304 steel using 3 to 7 layers. The maximum strength of the martensitic steel was 1370 MPa. The composite sheets had strengths in the range 950-1200 MPa, depending on the number of layers and the proportion of the steels. A metallographic observation of the fractures revealed that the first occurrence was fracture in the martensitic steel layers, followed by deformation of the layers of tough austenitic AISI 304 steel. The notch toughness values were the highest when the notch was oriented from the sheet surface to the sheet interior. Keywords: laminated composite, steel sandwich, tension test, hot rolling, notch toughness V delu je opisana izdelava laminiranih jeklenih kompozitov z vro~im valjanjem. Kompozitni sestavi so bili narejeni iz martenzitnega nerjave~ega orodnega jekla s pove~ano vsebnostjo du{ika, in v skladu s standardom AISI 304 je bilo uporabljeno jeklo s 3 do 7 sloji. Maksimalna mo~martenzitnega jekla je bila 1370 MPa. Mo~kompozitnih slojev je bila med 950-1200 MPa, odvisno od {tevila slojev in proporcev jekla. Metalografska analiza zlomov je pokazala, da je najprej pri{lo do zloma pri slojih martenzitnega jekla, sledila je deformacija slojev te`kega avstenitnega jekla AISI 304. Vrednosti`ilavosti v zarezah so bile najvi{je, kjer je bila zareza usmerjena iz povr{ine sloja v njegovo notranjost. Klju~ne besede: laminirani kompozit, sestav jekla, napetostni preizkus, vro~e valjanje,`ilavost zareze
