What is NOT the welding inspection methods Visual Ultrasonic

What is NOT the welding inspection methods? Visual Ultrasonic Magnetic particle, liquid penetrate Gamma-ray X-ray Porosity in welding process can be reduced by proper selection of and by welding speeds. Electrodes, reducing Electrodes, increasing Welding temperature, reducing Welding temperature, increasing In welding process. is caused by compounds, such as oxides and fluxes that are caught in the weld zone Porosity Slag inclusions Incomplete fusion and penetration Cracks In welding process, which one is NOT an effective method to prevent incomplete fusion? Raise the temperature of the base metal Provide sufficient shielding gases Clean weld area prior to welding Increase the travel speed during welding In Welding process, which one is NOT the method to prevent the cracks? Preheat the components to be welded Rapid cooling of the welded component Modify the joint design to minimize stresses developed from shrinkage during cooling Change the parameters, procedures, and sequences of the welding operation In welding process, which sequential combination is the correct mark for each welding defect: under fill-crack-undercut-porpsity in the figure below? 1-5-6-2 1-3-6-5 6-3-1-2 6-2-1-5

Solution

11) Anser is option \"c\".

The magnetic particle and liquid penetrate is not the same NDT testing method as in magnetic particle testing the yoke magnetic field is used and in liquid penetrate a developer is sparyed and inspected visually.
