In order to improve the tribological properties of titanium alloy Ti6Al4V composite surface
layers Ti/TiN were produced during laser surface gas nitriding by means of a novel high …

The autogenous laser welding of 2.5 mm thick butt joints of thermomechanically rolled fine-
grain steel grade S420MC was investigated. Butt joints were laser welded by the Yb: YAG …

The article presents the results of investigations on autogenous laser welding of the new-
generation advanced high-strength steels (AHSS) Domex 960, classified as …

Metallographic examination revealed that the concentrated electron beam significantly
affects the changes of microstructure in the weld and the adjacent heat affected zone (HAZ) …

The study addresses the results concerning the laser welding of TRIP (TRansformation
Induced Plasticity) steel using a beam focused at two spots (also referred to as twin-spot …

In welding processes, many factors contribute in achieving a required quality of the welds.
Those factors are numerous and they may interact with each other, affecting response …

Laser welding is the widely used method in steel industries to join hot-rolled coils and repair
mold steel, railway axles, and automotive pressure sensors. Failures in these welds can …

This work presents the results of a microstructural characterization of welds in Nb-
microalloyed TRIP steel with silicon partially replaced by aluminum. Tests of laser welding of …

In the paper the results of metallographic examination and mechanical properties of electron
beam welded joint of quenched and tempered steel grade S690QL are presented …

In this review paper an attempt has to be made to understand the effects of different heat
input values on microstructure of parent metal (PM), the coarse heat affected zone (CGHAZ) …
