There is often a friend asked flux welding consumables will not corrode, and if that is how to solve it? Love stand the flux to do the following answer on how to solve this problem soldering flux corrosion of weldments, want to help people. No matter what kind of flux on welding consumables has certain corrosive, just corrosive size, high activity flux indeed improve the operation of electronic butt weldability, but also very serious corrosion of weldments. Because the flux has an organic acid component is present, even if it is a pure pine fragrance (in general of the rosin acid content of the resin is 85.6 to 88.7%, fatty acid content of 2.5 to 5.4%, neutral substance content of 5.2 to 7.6% fatty acid) around the generally radiate around the weakly acidic 4.0-6.5 PH value, even out of the volatile gases are the presence of the organic acid component, the metal corrosion. Of course, some flux appropriate add some other ingredients as corrosion inhibitors, antioxidants, stability, corrosive mitigation role, but that does not mean that it is not corrosive, is only a short-term can not see it. But the use of welding flux is inevitable, therefore recommendations need to be cleaned after welding too, such flux residues can all be washed after not corrosive weldments. Flux weldments corrosion prevention reduce but not completely eliminate only.
