Tianjin lead alloy welding Introduction: Lead solder alloy is a non-ferrous metal welding rare soldering, welding work at 300-400 degrees melting point and low thermal conductivity, commonly used in low-temperature brazing. We illustrate the use of the M51 which has introduced to the activity with the M51-F flux can be welded zinc alloy and lead alloy under low temperature M51 179 degree environment. Here comes the lead groove weld repair is a welding involves various angles, plus a greater density of lead, was 11.34g / cm3, and a low melting point, high liquidity, and therefore when horizontal welding and overhead welding very difficult, if handled badly, can make a lot of falling molten stream, so the choice of WE-34T lead alloy welding wire.
