This disclosure relates to MIG welding. In order to obtain an instantaneous short circuit type of metal transfer in the process using only a pure inert gas shield a small amount of rare earth elements is added to the weld wire. The amount of rare earth added is between 0.02%-0.03% by weight of the wire.

MIG Arc welding method

Surfacing is conducted with horizontal electro-slag welding by using a strip electrode, and by applying a magnetic field, having component perpendicular to a base metal, to a molten metal and slag pool to control the flow of the molten pool.

Horizontal electro-slag welding process for surfacing

A method of welding corner joints by means of a multiple electrode submerged-arc welding and adapted to be utilized for the manufacture of a hollow square steel pillar and the like structural frameworks is disclosed. The method of welding is effected under the following three conditions:
