I am having a problem soldering tubing. I drew 6.5mm tubing from
0.8mm sheet Argentium. It had a tight seam.
I heated it from below with the seam and hard Argentium solder on
top. Theseam keeps spreading open. I’ve annealed, redrawn the
tubing, same problem.
I have made tubing before, including with Argentium, have not had
this happen. Why is this happening? Is this metal too thin for this
I need tubing of these dimensions, also 8.5mm Argentium tubing,
1.2mm wall thickness or heavier (for a hinge). Can this be purchased
