soldering and welding
Welding uses steel rod, which is melted into the joints or voids. Strongest of the three.
Soldering is similar, except a low temperature melting point lead//tin alloy is used. Weakest of the
three. Also there os silver solder, somewhat stronger.
othing really. It concerns the metal your working with. You braze with brass, solder with lead and weld
with steel. That's about it.
Soldering is a joint repair for two pieces of metal, like a chip to a circuit board using lead.
Welding is taking two pieces of metal and heating them up to the same temperature and making
a single piece of metal out of two seperate pieces.
I was taught that soldering,as it relates to piping, is the heating of the base metal to a point to
where the filler metal will melt and fill the gap between the two pieces of metal being soldered.
The base metal is NOT melted, only the filler metal. Soldering is usually used to join non-ferrous
metals. Welding is when the base metal is heated to a point where it will melt and , with the filler
metal, becomes part of the weldment. In other words, the two pieces become one, and the
resulting weld is now a blend of base metal and filler metal.
