Zusammenfassung:Title screen
The paper reports changes in strain fields on welded sample surfaces from commercial pure titanium, joined by both laser beam welding (LBW) and gas tungsten arc welding (GTAW) procedures, under uniaxial tensile loads. Their dynamics were investigated by the digital image correlation method using a ‘Vic-3D’ optical system. In addition, stress-strain curves were drawn in both ?eng-?eng and ?true-?true coordinates. It was shown that the laser welded sample was characterized by a higher ultimate tensile strength to yield point ratio than the as-received one. The GTAW sample fractured under much less stresses than the LBW one.
