Probably not, no. Iron is an example of a ferromagnet. These loose their magnetism when heated above the Curie Temperature. This is typically lower than the melting point. So an arcwelder will destroy any magnetism in the material.

Magnetism is a function of the crystaline structure of metals.

In liquid form, there are no crystals.
