Q: How to solder metal frame hinges?
A: Clean any corrosion away from the surface for being soldered with fine emery cloth. Such as corroding optical frame temples, etc. You should never mar the completed in other locations that will spoil the look off the frame.
Clean areas with the frames and hinges the location where the solder will attach them together. Use solvent and also a rag to clean away any oil, grease, or fingerprints.
Apply soldering flux on the areas for the frame and hinges the place you will solder.
Squeeze frame a vise and employ clamps to hold the hinge set up. The hinge must fit flush because the solder will never fill gaps. And it must remain steady during the entire soldering process. When the joint moves even slightly while solder cools, the joint will fall apart while using slightest pressure. It must remain perfectly still.
Heat the joint with the torch a couple of seconds, and then touch the solder towards joint. The solder should melt and flow to the joint by capillary action. When the solder doesn't melt instantly when touched, the joint isn't hot enough yet.
Wait for the solder for cooling before moving the frames. The solder should harden within 10 seconds, but the frames may remain too hot to the touch much more time, with respect to the size and thickness in the frame and hinges.
Offer the frames gently in a rag while loosening the vice and clamps. When you find yourself sure the frames are cool enough to touch, clean the soldered joint using the solvent and rag to clear out any residue in the soldering flux.
