Effect of welding parameters on pitting corrosion rate of pulsed current micro plasma arc welded AISI 304L sheets in 1N HCl
Austenitic stainless steel sheets have gained wide acceptance in the fabrication of components, which require high temperature resistance and corrosion resistance such as metal bellows used in expansion joints in aircraft, aerospace and petroleum industries. In the case of single pass welding of thinner sections of this alloy, Pulsed Current Micro Plasma Arc Welding (PCMPAW) has been found bene...

متن کاملPROCESS CONTROL AND DEFECTS IN Ti-6Al-4V ADDITIVE MANUFACTURING, USING PLASMA TRANSFERRED ARC (PTA) TECHNIQUES
Defects during Plasma Transfer Arc (PTA) beam fusion additive manufacturing (AM) processing of Ti-6Al-4V, including lack of fusion, porosity variations, and solidification cracking, have been monitored using near infrared (1.62 μm) imagery at 300 Hz, 300 μm spatial resolution and melt pool sizes of greater than 12μ. The temperature evolution exhibits a periodic temperature modulation of more th...
متن کاملapplication of grey relational analysis for optimizing weld pool geometry parameters of pulsed current micro plasma arc welded aisi 304l stainless steel sheets
pulsed current plasma arc welding (pcpaw) is one of the most widely used welding processes in sheet metal manufacturing industry. in any fusion arc welding process, the weld bead geometry plays an important role in determining the mechanical properties of the weld and hence quality of the weld. moreover, the geometry of weld bead involves several simultaneously multiple quality characteristics...
متن کاملDestruction of organo-halogenated compounds by DC non-transferred arc plasma
The actual technologies for the destruction of organo-halogenated substances are reviewed and compared with the emerging plasma processes based on the non transferred arc plasma torches. The associated costs are presented.
