Can you overheat copper pipe when soldering? Overheating is a major problem when brazing or soldering copper pipe because the flux will burn (become oxidized), stop working, and become a barrier to tinning. In addition, a heavy oxide can be formed on the pipe itself, preventing a bond from forming between the filler metal and the pipe surface.
Can you overheat a solder joint? If the solder does not melt, remove it and continue heating. CAUTION: Do not overheat the joint or direct the flame into the face of the fitting cup. Overheating could burn the flux, which will destroy its effectiveness and the solder will not enter the joint properly.
Can you use too much solder on copper pipe? Don’t feed too much solder into the joint. It’s tempting to melt a few inches of solder into a joint as extra insurance against leaking. But excess solder can puddle inside pipes, restricting water flow, and can form small balls that break loose and damage faucet valves. Use about 1/2 in.
How long does it take to heat a copper pipe for soldering? The biggest mistake a rookie makes soldering copper is they allow the heat of the torch to melt the solder. Do NOT do that. You must heat the copper tubing and fitting for about ten or fifteen seconds before touching the solder wire to the hot copper. The HOT copper will melt the solder, not the torch.
