Choko Care Interview Questions and Answers

There are four main types of welding positions: flat, horizontal, vertical, and overhead.

• Flat position: Welding is done on a horizontal surface.

• Horizontal position: Welding is done on a vertical surface, with the weld axis in a horizontal plane.

• Vertical position: Welding is done on a vertical surface, with the weld axis in a vertical plane.

• Overhead position: Welding is done on the underside of a horizontal surface.

There are various types of welding electrodes used in different welding processes.

• Welding electrodes are classified based on their composition, coating, and current type.

• Common types of welding electrodes include E6010, E7018, and E308L.

• Different electrodes are used for specific applications such as mild steel, stainless steel, and aluminum welding.

• Some electrodes are designed for specific welding processes like shielded metal arc welding (SMAW) or gas tungsten arc welding (G...read more

There are three types of parameters in Radiography: exposure parameters, image quality parameters, and patient-related parameters.

• Exposure parameters include kVp, mA, and exposure time.

• Image quality parameters include spatial resolution, contrast resolution, and noise.

• Patient-related parameters include patient positioning, patient size, and patient motion.

• Other parameters may include focal spot size, source-to-image distance, and image receptor type.

There are several types of NDT inspections used in various industries.

• Non-destructive testing (NDT) is a method used to evaluate the properties of a material, component, or system without causing damage.

• Some common types of NDT inspections include visual inspection, ultrasonic testing, magnetic particle testing, liquid penetrant testing, radiographic testing, and eddy current testing.

• Visual inspection involves the direct observation of a component or material to detect any vi...read more

The density of RT film refers to its mass per unit volume.

• Density is a measure of how much mass is contained in a given volume.

• In the case of RT film, density is typically expressed in grams per cubic centimeter (g/cm³).

• The density of RT film can vary depending on factors such as the specific material used and the manufacturing process.

• Density is an important property to consider in quality control as it can impact the performance and characteristics of the film.

• Measuring the...read more
