“…Besides the applications of MRW, an interesting study was performed by [41] in resistance welding when joining thin walled NiTi tubes to create ordered architectural cellular structures as an alternative to other manufacturing technologies to produce porous structures in NiTi for biomedical and other applications. Two tubes were joined along their generatrix, using superelastic NiTi with 7 mm outer diameter and a wall thickness of 0.2 mm.…”

“…Micro welding of dissimilar metals not only can meet the needs in the manufacturing industry but also is an effective way to realize multiple performance requirements, especially for microelectronics and with sensitive materials. There are numerous common micro welding methods, e.g., electric resistance welding [1], friction welding [2], laser welding [3], and electron beam welding [4]. Laser micro welding has gained popularity owing to advantages as such as its high energy density, concentrated heat source, small heat affected zone, good controllability, and low environmental requirements.…”

Micro welding of dissimilar metals can meet many performance requirements for modern engineering structures. In this experiment, laser micro welding of copper-aluminum dissimilar metals was conducted with an HWLW-300A energy negative feedback Nd:YAG pulse laser. By using the overlap welding method with copper on aluminum, with the laser energy being distributed unevenly, good weld joints were obtained. In this paper, the welding mechanism was analyzed from aspects such as welding temperature and the specific heat capacity of the solid metal. Existing defects were identified, and a feasible improvement scheme was proposed.and has currently become one of the most important and advanced manufacturing technologies in fields ranging from the aerospace industry to ship building and automobile manufacturing. Through half a century of development, laser micro welding of multiple dissimilar metals has been realized [5] [6] [7].Nevertheless, this does not mean that laser micro welding of all dissimilar metals can be realized. The process of laser micro welding of dissimilar metals relates to multiple physical effects [8], so there are still many difficult problems to solve both experimentally and theoretically. Studying laser micro welding of more dissimilar metals and its mechanism remains a theme explored by researchers.Copper and aluminum metals are widely used in electronics. Partial substitu-J.

“…Heat of transition is generally measured by DSC [8] or Differential Ther-8 mal Analysis. All these classical techniques allow a global measurement of 9 the desired property at the specimen scale. However, in some cases, a local 10 measurement of these properties would be useful, for example in the case 11 of heterogeneous specimens [9] or graded material [10,11].…”

This paper proposes a non-contact original method to estimate local thermophysical properties (heat capacity and thermal conductivity) and heats of transition from plane thin specimens. This method is based on measurement of temperature fields with an infrared camera during a drop calorimetric experiment. A studied specimen and a reference specimen, with similar geometries, are simultaneously tested. Firstly, the method is validated by estimating heat capacity and thermal conductivity of Vanadium specimens and by comparing the determined values with those obtained by Differential Scanning Calorimetry and by a laser flash method, respectively. Secondly, the method is used to determine latent heats of martensitic transformations. Delobelle et al, Exp. Mech., Exp. Mech., 55, pp 711-723, 2015 dance with results obtained by Differential Scanning Calorimetry.
