It means that the battery of cell phone jammer can be charged.And the maximum pulse current of this kind of battery used by cell phone jammer is 800mA
When cooled to 400 ~ 350 ℃ continuous, granular or massive ferrite matrix high-carbon austenite islands (which can further change the MA group), the so-called granular bainite [25]. Compare the three to defend the access speed the M170P side of the heat affected zone can be seen that with the increase of welding speed, granular bainite content decreases, the organization of the grain size decreases, the heat affected zone width decreases. This is because the welding speed, speed up the cooling rate also will be accelerated, which raised grain caused by the welding thermal cycle phenomenon has a certain extent. DC06 lateral organization of the heat-affected zone in welding speed change 3.3.5 on the performance of tailor welded blanks. This kind of battery of cell phone jammer should be equipped with the corresponding charger. Weld heat affected zone width increased significantly with increasing frequency (M170P side from 310um to 460um, DC06 side from 400um to 630um). This is mainly because of the attendant increase in pulse frequency, the same welding speed, per unit length of the pulse number increased, so that an increase in the width of the heat-affected zone. 2 # # 18Hz, 20Hz Figure 3.3 the cross-section of the welded joints 3 # 22Hz so the extent permitted by the width of the heat-affected zone, you should try to increase the pulse frequency, pulse frequency, spot size and welding speed are matched with each other, in order to achieve the required overlap ratio. The battery of cell phone jammer can be charged if it is used out. This test makes the detection of solidification rate possible. Metallographic erosion can show the organizational structure of the solidification structure. Level of the cut of this grade of steel in the vertical center position of the deposited metal is able observed, often called the center of the weld zone, the center of the weld makes raw materials, the growth of dendrites by inhibition . Figure $ 43 Anhui University Graduation Project (Thesis) Paper 1 of the report shows the macro-and microstructure of the different kinds of steel (Fe360, IFS, and HR), and welds. In addition, taking into account their composition, the crystallization process occurs in the austenite is transformed ferrite process. The initial organization of the ferrite - pearlite (dα = 10μm) and pearlite island can be observed in a relatively short distance (heat affected zone). When the weld zone and heat affected zone has a higher cooling rate will be the formation of martensite. Actually, this kind of 3 in 1 cell phone jammer is really practical and popular in both the domestic market and oversea market.
