An arc welding process wherein coalescence is produced by heating with an arc between a continuous filler metal (consumable) electrode and the work. Shielding is obtained entirely from an externally supplied gas, or gas mixture. MIG welding requires the use of an inert shield gas.

A composite tubular electrode consisting of a metal sheath and a core of various powdered materials, producing no more than slag islands on the face of the weld bead. External shielding is required.

A tubular electrode process where the hollow configuration contains alloying materials.

Similar to Metal Inert Gas (MIG) Welding.

The temperature range between solidus and liquidus.
