TL;DR: In this article, the strength differences between laser-spot and resistance-spot welds must be ascertained before LSW can be implemented in selected applications, and the low-cycle fatigue strength and residual stress of laser spot welded specimens were measured and compared with those of RSW results.

TL;DR: In this article, three welding speeds designated as low (1.5mm/s), medium (2.5 mm/s) and high (3.5 millimeters/sec) were operated during gas tungsten arc welding (GTAW) process and joints made were subjected to analysis of the microstructures, mechanical and corrosion properties of the joints.

TL;DR: In this article, the influence of laser power modulation during copper welding on weld imperfections is discussed and it is shown that a sinusoidal power modulation leads to a strong reduction of melt ejections and also to an increase in penetration depth.

TL;DR: The morphology and structure of the weld interface in magnetic pulse welding of similar and dissimilar metals were investigated in this paper, where extensive characterisation techniques were used, including the focused ion beam (FIB) method, to prepare a cross-section of the Al-Mg interface for TEM characterisation.
Abstract: The morphology and structure of the weld interface in magnetic pulse welding of similar and dissimilar metals were investigated. The interface zone of dissimilar metal couples such as Al–Mg, was studied in comparison to Al–Al welds. It was found that intermetallic phases (IMP) of different compositions are created during welding of the Al–Mg couple by rapid solidification of a thin melted layer at the interface. According to the calculated energy balance of magnetic pulse welding (MPW), there is enough energy to melt a thin interfacial layer and create IMP. Intensive characterisation techniques were used, including the focused ion beam (FIB) method that was used to prepare a cross-section of the Al–Mg interface for TEM characterisation. It was established that the jet action plays an important role in the melting process at the bonding zone.

05 Apr 1994TL;DR: In this paper, a thin layer of metal mesh is formed on the surface of the implant for the bonding with a porous surface layer (16) to prevent the formation of notches within the body of implant.
Abstract: The method forms a thin layer of metal mesh (14) on the surface (12) of the implant (10) for the bonding with a porous surface layer (16) to prevent the formation of notches within the body of the implant (10) The layer of metal mesh (14) can be formed by a number of known methods including conventional welding processes such as arc welding, resistance welding, electron beam welding, laser beam welding, friction welding, ultrasonic welding, cladding The porous metal surface layer (16) is preferably formed from titanium wire or titanium beads in a known process The porous surface layer (16) is bonded by a known process such as diffusion bonding, sintering, welding, or cladding By bonding the porous surface layer (16) to the thin layer of metal mesh (14), notches normally formed in the body of the implant (10) are substantially eliminated Therefore, the designer of the implant (10) is not limited as to the location and amount of porous surface layer (16) to be placed on the implants (10)
