Abstract

PURPOSE: To perform penetration of a start part sufficiently and prevent oil leakage, air leakage, etc., by carrying out welding by setting the initial electric current at the start of welding at a value slighting larger than steady current.
CONSTITUTION: Arc welding is carried out by setting the initial electric current at the start of welding at a value larger than that of steady current. If the current value is increased, penetration increases and the penetration is accomplished sufficiently in spite of the absence of a temp. rise by the arc heat in the start part of welding. It is preferable to set the initial current at the current value larger by about 1/3W1/4 than the steady current.
