Abstract
A method of welding metals wherein the size and shape of a weld pool as w as the traversing of the arc from one metal to the other is commanded magnetically by predetermined data, which data is updated by observing and characterizing isotherms in the weld pool, comparing the observed isotherms with a predetermined set of desired isotherms and then updating the command data for optimum performance.
