Quality strongly depends on good mechanical properties of any manufacturing material. Similarly, quality Tungsten Inert Gas (TIG) welding Duplex Stainless Steel (DSS) like percentage elongation, ultimate tensile strength etc. Better Percentage Elongation (PE) is produced using proper parameters and their values at the time TIG welding. In this study, has been done ASTM/UNS 2205 duplex stainless...

Minor problems arising from optimizations by welding of fixed prostheses frameworks can be identified by macroscopic and microscopic visual inspection. The purpose of this study was to highlight the visible discontinuities present in the laser welds of dental Ni-Cr alloys. Ni-Cr base metal alloys designated for fixed prostheses manufacture were selected for the experiments. Using cast plates, p...

Process monitoring is important for the laser welding system, especially for the weld seam deviation monitoring. A 10kW high power fiber laser butt joint welding of type 304 stainless steel was performed. By combing two different band pass filters, high speed photography was employed to capture the near-infrared images of molten pools. Image difference algorithm was used to obtain the weld seam...

The feasibility of using laser–cold metal transfer (CMT) misaligned hybrid welding to join an X80 line-pipe steel in a narrow gap configuration was investigated. laser beam interacted with the sidewall and its bottom at small angle, while CMT arc acted on backside beam. influence distance parameter between spot tip wire formation defects filled weld were Narrow bevel welds performed, joints ten...

Cracking of laser hybrid welding of eccentric fillet joints has been studied for stainless steel. Laser hybrid welding enables narrow deep welds with freedom for shaping the upper weld geometry. The significance of geometrical aspects like weld toe radius, weld surface topography and lack of fusion on fatigue cracking is discussed. Constant amplitude four point bending tests, S/N-curve, topogra...

The punchless welding point detection system using laser diagnostics for continuous strip production line has been developed. At the entrance of the steel strip production line, the preceding and following coils are welded for continuous processing. The welding point detection and tracking of the position is essential for the setup change of various important processing facilities according to ...
