Temperature change of work piece was affect by material properties, thermodynamic performance and change of processing conditions, such as friction coefficient of interface , velocity can affect the change of temperature and temperature distribution.

In the study, thermal efficiency in MIG welding of aluminum alloy with longitudinal magnetic field was analyzed, as well as softening behavior of heat-affected zone (HAZ) and base metal were investigated.
The applications of electromagnetic field in welding is a new developed technology in recent years, by which the welding arc shape, melting droplet transition and crystallization process of liquid metal in the molten pool are influenced through additional magnetic field, accordingly refining weld crystal organization and improving mechanical properties [2]. 
DuPont had demonstrated that melting efficiency can be predicted from the welding parameters and material properties by the equation 5 [9]

But when exciting current intensity continued to increase, microstructure and mechanical property of HAZ did not change obviously.

The mechanical properties of the friction stir (FS) welds are strongly affected by the grain size in solid-solution strengthening materials [7, 8].
Since the grain size of the high-temperature deformed material mainly depends on the strain rate and temperature when the strain is high [9], both the strain rate and temperature are important factors for understanding the microstructural evolution during FSW.
In these factors, the temperature can be experimentally measured during FSW using thermocouple [10, 11].
In the plane-strain compression test, strain was about 5 in the midsection of the specimen at reduction ratio of about 83 %, which was hardly affected by the compression rate.

The aim of present work is to investigate the properties of weld bonded DP600 with KS2 specimen.
The adhesive is applied in thin layers (0.3 mm), to obtain optimal mechanical properties.

Introduction Interstitial atoms greatly affect the thermodynamic and mechanical properties of metals due to large strain effects produced on the host atoms of metals.
It is still of great interest and importance to have such information for predictions of different properties of interstitial alloys.
The factor δ/T incorporates the temperature dependence of the relaxation strength [12,15].
The relaxation time relevant to the p-th O atom is where kB is the Boltzmann constant and τ0 the pre-exponential factor.

Fig.1 System configuration of DSTATCOM When DSTATCOM is used to compensate power quality caused by reactive current of load or to improve voltage quality of PCC, it is mainly through injecting a current with magnitude equal but direction opposite to reactive current of load into power grid, or injecting some reactive current to improve the voltage quality of PCC. 2．Detection of Reactive Current Reactive current detection is a important part of DSTATCOM functions, and its detection unit performance directly affects the compensation effect of the whole DSTATCOM device.
Serving as parallel compensation device of power system, besides mitigating harmonics, compensating unbalanced voltage and power factor, DSTATCOM can still effectively mitigating voltage quality problem such as voltage sag, voltage flicker etc; The study result proposed in the paper also provides reference for the engineering application of DSTATCOM device, and proper control mode can be selected depending on different compensation purpose of DSTATCOM.
