Dissimilar Welding of EN 10025 Carbon Steel to AISI 316L Stainless Steel by Friction Stir Welding

In the present Study, a dissimilar joint of carbon steel sheet EN 10025 with 316 L has been welded by FSW and the welding parameters were optimized by RSM software method. For investigation of mechanical properties and microstructural analysis carried out by using optical, scanning electron microscopes with EDS analysis, tensile and hardness test of different area of joints, SZ, TMAZ, HAZ, thei...

Plasma Plume Oscillations Monitoring during Laser Welding of Stainless Steel by Discrete Wavelet Transform Application

The plasma optical radiation emitted during CO2 laser welding of stainless steel samples has been detected with a Si-PIN photodiode and analyzed under different process conditions. The discrete wavelet transform (DWT) has been used to decompose the optical signal into various discrete series of sequences over different frequency bands. The results show that changes of the process settings may y...

Microstructural Study of 17-4PH Stainless Steel after Plasma-Transferred Arc Welding

The improvement of the surface qualities and surface hardening of precipitation hardened martensitic stainless steel 17-4PH was achieved by the plasma-transferred arc welding (PTAW) process deposited with Co-based alloy. The microstructure of the heat affected zone (HAZ) and base metal were characterized by optical microscope (OM), scanning electron microscope (SEM) and transmission electron mi...
