The paper deals with various metallurgical problems associated with good welding in steel. Metallurgical background of defects like hot crack, hot tear, cold crack, weld metal and heat affected zone brittleness have been discussed from the point of view of weld metal and base metal compositions, impurities and deoxidation conditions. The role of oxygen, hydrogen and nitrogen and various inclusions, their distribution and morphology have been examined.
