Soldering Soldering Tips and Procedures Soldering is most likely the most difficult craft to master. A good solder joint should hold up for the life of the horn. Cleanliness is the key to good solder joints.
Materials selection can help make the job easier and produce a stronger joint.
There are also a few tools which are necessary to do the job well. It is up to you to try these and see which works best. You effect the strength of the soldered joint by the amount of lead or tin content. Over time, the tin will crystalize weakening the joint. Tin, more than lead, is effected by a wide variety of chemicals.
