Ud. Mallya et Hs. Srinivas, MAGNETIC STEERING OF ARC AND BEAD CHARACTERISTICS IN SUBMERGED-ARC STRIP CLADDING, Welding journal, 72(11), 1993, pp. 190000517-190000522
Submerged arc strip cladding has been widely used when larger thicknes
ses of clad materials are required. Use of wider strips and higher cur
rent have all been attempted to achieve higher productivity and these
have been associated with arc blow phenomena and unacceptable bead cha
racteristics. Investigations were carried out to study the effect of v
arious magnetizing parameters (flux density, dwell time) and welding c
urrent on the bead characteristics, using 60-mm-wide strips of 309L st
ainless steel. Results of the investigation indicate very encouraging
trends in increasing the melt-off rate/bead height and decreasing pene
tration and hence dilution by 23%. The magnetizing flux density indivi
dually did not indicate significant influence on any of the bead chara
cteristics studied.
