Mathematical modeling for the prediction of depth of penetration in double pulse GMA welding using fractional factorial method

The quality of weld joint is directly influenced by the input process parameters influenced by various process parameters during welding. The weld quality can be decided by bead geometry viz., depth of penetration and bead width. Inadequate depth of penetration will lead to failure of the welded str...
