Tungsten Inert Gas (TIG) welding is otherwise known as the Arc soldering (GTAW) process which when significant levels of weld quality or high precision are required, to represent an advanced arc process. However impact factors on this form important for its produced in single-pass welding. In investigation, autogenous was performed a carbon mild steel plate with four parametric variables. High ...
The prediction of the weld bead geometry parameters is an important aspect welding processes due to it related strength welded joint. This research focuses on using statistical design techniques and a deep learning neural network predict shape shielded metal arc (SMAW), inert gas (MIG), tungsten (TIG) processes. With techniques, experiments were carried out obtain data for generating regression...
EDF Energy has the requirement to detect and size lack of penetration type defects in thin-walled stainless steel components. A high frequency ultrasonic phased array inspection technique has been successfully developed and applied to thin walled pipes and is currently used as an ENIQ qualified inspection on nuclear plant. The welds are manufactured with an autogenous Tungsten Inert Gas (TIG) w...
In this study, TIG welding was used to clad and repair the surface of cast AZ91C magnesium alloy. Then, friction stir processing and T6 heat treatment wrer applied on the welded region. Microhardness results showed an improvement in the mean hardness of welded zone and also FSPed zone. Increase in the mean microhardness of the welded zone after T6 heat treatment to the maximum value was also co...
The present study presents a numerical prediction of residual stresses (RS) using the single-pass tungsten inert gas (TIG) welding process for stainless steel plates and two-pass TIG pipes. effect heat exchange between material environment was studied. work consists two parts: first one is based on determination existence numerically Cast3M software, which has been validated by literature resul...
Current guidelines favor the radial approach for coronary angiography. Therefore, specialty radial diagnostic catheters were designed to engage both coronary arteries with a single device. However, it is unclear if single catheters are superior to conventional catheters. A retrospective analysis was performed of consecutive right radial coronary angiographies to determine catheter use, fluorosc...
