Abstract

In this work are given the testing results of mechanical properties welded joints and microstructure of micro alloyed steel as well as its sensitivity to lamellar cracks appearance. The obtained results show that steel has good resistance to lamellar cracks appearance and with an appropriate wire choice for welding, a good combination of mechanical properties could be obtained at room (ambience) temperatures as well as at low temperatures.

Keywords

micro alloyed steel welding; mechanical properties; microstructure; lamellar cracks
