The usa.e of c.ntinuous c.oling tra.sform.tion （c.T） dia.ra.0} in num.ric.0} welding sim.la.ions is sta.e of the a.t. Nevertheless, spec.fic.0}ions provide lim.ts in c.em.c.0} c.m.osition of m.teria.s whic. result in different c.T beha.ior a.d c.T dia.ra.0}, respec.ively. Therefore, it is nec.ssa.y to a.a.yze the influenc. of va.ia.ions in c.T dia.ra.0} on the developing residua. stresses. In the present pa.er, four c.T dia.ra.0} a.d their effec. on num.ric.0} c.0}c.la.ion of residua. stresses a.e investiga.ed for the widely used struc.ura. steel S355J2 ＋ N welded by the ga. m.ta. a.c.welding （Gm.W） proc.ss.
