Si loo daboolo baahida suuqa, shirkadeena waxay soo saartey heerkul aad u hooseeya oo kala duwan, qallafsanaan sare oo austenitic ahama electrodes, ka kooban kiimikaad ee birta kaydsan (sida ku cad Shaxda 1) iyo sifooyin farsamo oo deggan (sida ku cad shaxda). 2), oo uu leeyahay heer aad u fiican oo dhan-bog alxanka habka Waxqabadka, iyo heerkul hoose oo aad u fiican saamayn adag, saamaynta ay qadar ferrite on qiimaha saamaynta (Shaxda 3).
