AWS E309-16 Welding Electrodes is stable austenite structure containing 22Cr-12Ni, of which certain ferrite is contained. It contains low carbon element and has good crack resistibility and excellent weldability.
Both AC and DC can be applied, it can be used for all position welding with excellent performances:stable arc, small apatters, good appearance of weld. And also the welding electrode shows good heat-resistance character, not easy to turn red.
AWS E309-16 Welding Electrodes is suitable for welding low carbon stainless steel and coated steel, SUS309S, 13Cr with heat-resistance, 18Cr rust or dissimilar metal.
1. Before welding, the welding electrodes should be baked at the temperature from 300 to 350 ℃ for one hour.
2. The stainless steel brush must be used to clean the weld seam, in order to avoid iron fillings penetrating there to affect its quality.

Incomplete gear mechanism structure design The incomplete gear mechanism consists of a standard analog spur gear 7 and a partial gear 5. The incomplete gear 5 is a combined gear which can be freely disassembled or indexed by the incomplete gear seat and the incomplete gear ring. The number of teeth can be adjusted within the range to meet the requirement of the mm blank length.
Incomplete gear ring zm5 Incomplete gear seat zm53.1 Incomplete gear seat zm5 Design Incomplete gear seat is the main body of the incomplete gear 5.
The main design features are: the inner hole of the incomplete gear seat with the keyway is connected with the shaft O1―O1 through the key, and the shaft rotates incompletely. The left side has a convex disk diameter, which serves as a shaft diameter for forming a transition fit with the phase fittings, and functions to position and assemble the concentricity. On the same circumference of the gear plate surface, there are five groups of identical groups of A, B, C, D, and E; each group has three holes, two sizes of apertures, and the slightly larger ones are screw holes and small. It is a hinged hole for positioning and fixing when the incomplete gear 5 is assembled. Changing the number of teeth of the incomplete gear 5 is achieved by selecting a set of assembly holes at five different positions of the AE. There are incomplete teeth of 27 teeth on the tooth surface, which is the number of meshing teeth required for the wire feeding of the 200mm length of the binding wire, and the nominal number of teeth of the entire gear is 70 teeth.
Incomplete gear seat zm5=27 Reaming hole thread hole β disk diameter 3.2 Out of gear ring zm5 design Incomplete gear ring is an accessory of the incomplete gear 5, and the combination of the incomplete gear seat changes the number of teeth of the incomplete gear 5, It can achieve the effect of changing the wire length to process different specifications of the binding wire. The main design features of ferrous sulfate heptahydrate are: the inner hole of the incomplete gear ring is a hole with a transitional fit with the incomplete gear seat. It is easy to be concentric with the incomplete gear seat and can not completely complete the gear seat during installation. The shaft is indexed to change the number of teeth of the incomplete gear 5. The ring gear body has a set of two large and small holes on the disk surface, and the slightly larger ones are two through holes, and the small holes are the hinge holes for positioning and connection. The tooth surface is designed with 34 teeth with incomplete teeth. Nylon conveyor belt is the number of meshing teeth required for the size of the bundled wire 250mm. The actual number of teeth of the gear ring is 70 teeth. One ring is quite incomplete. The gear 5 is rotated by the nominal number of teeth. . The time from the unit speed: T01 = 3.57 s / min, available: t01 = 3.5770 = 0.051 s / tooth.
Unit tooth count wire length calculation The number of teeth that the incomplete gear mechanism meshed by the incomplete gear 5 and the gear 7 determines the time during which the equal-diameter wire feed wheels 13, 17 are rotated, thereby determining the wire feed length. From this, the length of the wire feed when the incomplete gear 5 is rotated over one tooth can be calculated. From n02=n03=0.76r/s and t01=0.051s/tooth, we can get: s=v line×t01=ω02Rt01=2πn02Rt01=2×3.14×0.76×30×0.051=7.30mm/tooth: R― The radius of the wire feed wheels 13, 17.
The design calculation of the number of teeth of the incomplete gear 5 and the calculation result of the assembly combination chart show that the wire length of the incomplete gear 5 is 7.3 mm per one tooth rotation. In the construction project, the steel wire bundle has six sizes, so it is easy to calculate The corresponding specifications are not the total number of teeth of the gear 5. When the bundled wire is produced and processed, as long as the number of teeth of the incomplete gear 5 is required, the corresponding length specification can be cut.
(1) The actual size of the bundling wire controlled by the incomplete gear transmission mechanism after design, processing and assembly is fully satisfied.
(2) In order to ensure that the end of the incomplete gear mechanism is engaged, the damper A is set on both sides of the shaft O3 - O3 as shown. The difficulty of adding a locking arc to the incomplete gear to process and variable length feeding is avoided.
(3) As a simple operation, practical and portable, it only needs to adjust the components of the incomplete gear - the assembly hole between the ring gear and the wheel seat can meet the requirements of the new specification length machining, and expand the application range for the incomplete gear transmission mechanism. .
(4) Incomplete gear mechanism In addition to controlling the processing of steel bars, food products, handicrafts, aluminum-plastic wire, gardening wire and electrical products, a large number of wire diameters, lengths of different lengths of wire cutting processing, etc. provide a wide range of applications .
