The present research article is focused to investigate the heating-and cooling-assisted friction stir welding (FSW) on dissimilar copper to stainless steel joints along with normal FSW. Gas tungsten arc welding torch was applied for heating-assisted source in front of the FSW tool, wherein preheating current was varied as 20, 40, and 60 A with rest of constant FSW parameters. Similarly, cooling-assisted FSW was performed by compressed air and water behind the FSW tool for constant FSW parameters, wherein the compressed air flow rate was varied as 15 and 30 PSI and water cooling was applied with 75 ml/ min one after another. Weld properties of assisted approaches were compared with normal FSW on the scale of macrostructure and microstructure analysis, tensile testing, and microhardness properties. The obtained results reveal that the normal FSW of dissimilar copper to stainless steel joint was observed as superior relative to assisted approaches. Surface oxides were observed for the welds of heating-assisted FSW and cooling-assisted FSW of compressed air. Elimination of surface oxides was noted for FSW assisted by water cooling. Highest tensile strength was reported for normal FSW relative to heating-assisted FSW and cooling-assisted FSW. Tensile strength was deteriorated as cooling conditions increase. The microstructures of the stir zone were observed as metal matrix type with Cu matrix and SS particles, wherein SS particles were reported as in random distribution with its varying size. Major defects were reported around the largely dispersed SS particles inside Cu matrix.

Quality Parameters of Explosively Welded Spring Steel and Carbon Steel

Explosive plating, or welding, is a process where part of the kinetic energy of the detonation of a certain amount of civil explosive material is used to accelerate the plate, which will form a welded joint upon an oblique impact on a stationary plate. The conditions that must be met to achieve a good weld are determined by welding criteria. Today, the most commonly used welding criteria are based on the speed of the collision point and the collision angle. In this paper a research is presented on explosion welding of two different steels and on quality of the obtained welded joint. Carbon steel and spring steel were welded using Amonex 4 explosive in different quantities. Basic characterization of the explosive was carried out: bulk density and detonation velocity were determined. Quality of the welded joint was inspected using the ultrasonic method. Possible intermetallic zones at the joint site created by the effect of increased temperature were examined by optical and scanning electron microscopy. Fracture toughness of the welded plates was determined, as well as hardness. The achieved experimental results were compared to theoretical predictions.

The microstructure evolution during dissimilar friction stir welding of copper with stainless steel 316L is studied. The welding is performed in transparence configuration using tools of two different geometries. The joints are characterized by optical microscopy, scanning and transmission electron microscopy, electron backscattered diffraction, and microhardness. The microstructure and crystallographic texture of base metals are significantly affected. The joint produced using a shoulder of 8 mm in diameter is characterized by a copper nugget with refined grains. The texture of copper is dominated by component of the shear texture. The steel beneath the tool shows a grain refinement with grains of sub‐micron size and a texture which is close to the ideal simple shear texture. For the joint produced by the 16 mm diameter tool shoulder, the nugget consists of large grains of copper, while the steel beneath the tool shows small recrystallized grains of micrometer size. The texture in the steel is dominated by the component of the shear texture. The Cu/316L interface in both types of joint is of very good quality. In a detailed study of the interface, it is revealed that the welding of metals is achieved by mutual intense mechanical interlocking without formation of any intermetallic compounds.
