However, the study by Elangovan and Balasubramanian [4] was conducted using FSP and that of Zhang et al [5] was conducted on similar joining of aluminium alloys, as such, research study into the effect of shoulder size on dissimilar materials is required due to the difference in their material properties.

Transient voltage waveforms used to assess arc stability during GTAW of samples of (a) RHP, (b) press-and-sinter and (c) wrought Ti-6Al-4V materials.
Typical weld zone microstructures for the three materials under investigation are shown in Figure 3.
The data presented below shows that the hardness levels in the HAZ of PS samples differ significantly from that of both RHP and wrought materials.

In addition, due to the excellent strength, high temperature stability, and corrosion resistance, hard passive alloys, such as nickel-based super-alloys, titanium and molybdenum alloys are widely used as aero-engine blade materials.
At present, electrochemical machining (ECM) has been developed as a main method for machining difficult-to-cut materials and shaping complicated contours and profile.
Being a non-mechanical metal removal process, ECM is capable of machining any electrically conductive materials with high stock removal rates regardless of their mechanical properties, such as hardness, elasticity and brittleness.

But in practical machining, it is hard to get the parameters by this way because of the different machine tools, different cutting tool and different materials.
The empirical formula of the life of the drill [1]: (m/s) (1) Where, Cv ——coefficient (which is related with drilling materials and feed ); T——life of drill(s); z, m, y——Index(which is the influence of d, T, f ); Kv——correction factor of cutting speed.

A model shows a system with simultaneous resin infusion from the inside and outside of the material.
Microscopic images of a slice from a part made with simultaneous resin infusion from the inside and outside of the reinforcement material.
In contrast, Figure 7 shows that resin impregnation via the guide sleeves resulted in relatively defect-free material.
