Specific examples go welding (change refers to the "):
A welding machine, the use of process:
Unplug the power, adding proper amount of gasoline, plug in the power, open a switch(according to the precious metal is different, can adjust 1, 2, 3 gear switch), ignitionand flame size adjustment (to the fine degree), welding
B refers to the specific process ":
A saw a finger ring off, according to the change the size of the circle, choice ofexpanding, shrink ring
B file to fracture file
C close the interface to the up, to the density
D with damp cloth or wet water paper gem tightly wrap, or the boric acid and alcoholsolution soak jewelry equipment to prevent leaching, jewelry black and protection ofprecious stones
E flux
F ring with 8 clamp fixed, ignition started welding
G fire tweezers and flux together and put some borax, quickly put the flame at theinterface, the flux melting in the interface, see the interface is up on all sides
H clamp ring let it cool. Can not directly into the cold water cooling, as gem cracking
I after cooling the ring to the iron bar shaped, with a hammer gently interface out
The j file to the interface file, thin consistency
K gem whether there is loose, if loose cloth cover the gem clip can be
L sanded interface, with skin wheel grinding interface
M bristle wheel waxing, polishing
N put the ring in the ultrasonic cleaning machine vibration cleaning, and then with a small brush scrub clean
O finally, suede can be wiped clean
Experience.
A changed the finger ring, to change the hour should be in the target finger ring and then narrowed a bit, because of changing for the better, but also on the ring ofbeating and grinding, which can then make the finger ring becomes large.
B refers to the ", should be changed to gold, first in the fracture on both sides of thewelding on the appropriate flux, then the gold embedded fracture walk welding need to join, is more susceptible to welding.
C gem ring before welding in the solution of boric acid and alcohol can make gold dipped going dark, can also play a role in the protection of precious stones
At the interface of D jewelry to play together, file, close, the docking neatly. Interfaceposition also can leave gaps of very fine, so is better, faster melting into the solder
E borax fluxing agent with borax can, walk, borax where flux are likely to go
F solder with temperature, which is where high temperature flux, high temperaturejewelry redness, so that red flux will go there
Note: the reason of flux with borax is taking, borax can improve the precious metalmelting point, so that the temperature increases
G stone after heating can not immediately into the cold water, as will the gem burst
H change refers to the "ring do not beat used brute force to the iron bar, so easy to make the gem collapse
I try not to burn with fire directly gem, but under special circumstances, when necessary, have a good heat to burn
Common with J Jewelry: package insert, insert, insert, clamping claw groove insert,cluster setting, jewelry can change refers to the ", is based on the modified gem not loose, fall off as the standard, so in the repair of careful observation of jewelry, usuallyto circle will change the stress structure, gem cause stones off can not be changed,and it can be changed
