steel
core of the rod to melt together, cooling quickly to form queue rails a solid bond

During
welding
, the flux that surrounds the rod’s core vaporizes, forming an inert gas that serves to protect the weld from
atm
ospheric elements that might weaken it,
welding
speed queue rails is important

rods, MIG uses a spool of continuously fed wire, which allows the welder to join longer stretches of
metal
without stopping to replace the rod
