One should pay attention to the following specifications while selecting a fluorescent tube for the X-ray machine:
 
1. X-ray source type:
Opt for the open source or closed source type, which is correlated with the resolution and life expectancy of the inspection devices. The more the resolution, the more will be the view of intricate and delicate details. If you inspect the target at a large scale, then it’s not an issue to choose the device with a relatively low resolution.

2. Target type:
The target type plays a vital role in influencing the distance between the sample and the X-ray source focus. This type will eventually influence the magnifying level of inspection devices. Hence, the target type should be reflective or penetrating.

3. X-ray voltage and power:
The penetrating ability of the X-ray source is always proportional to the voltage. Hence when the voltage is large, it is easier to inspect the objects with higher density and thickness. If the inspected target is single-sided boards, select the devices with low voltage. Similarly, if the inspected target is multi-layer boards, select the high voltage. At a certain voltage level, the image definition is proportional to the X-ray tube power.

The following are the parameters considered for the X-ray tube:
 
● Voltage in KV
● Tube current and tube power
● Target current and target power
● Relationship between tube power and target power
● Target current measurement
● Focus port size
● Spatial resolution
● Focal size VS geometric shading
● Feature resolution
● Detail detectability of the system

There are three types of X-ray sources listed below:
 
1. Open X-ray source (open source)
● Expensive
● It needs regular maintenance
● Can self-calibrate
● Filaments and targets are the consumables
● X-rays will be transmitted through the target
 
2. Conventional enclosed radiographic source (closed source)
● Not so expensive
● No need maintenance
● The life span of the tube life will be about 5000 hours. After that, the tube should be replaced
● As the tube ages, its focus will increase followed by the blurring of the image
● Here, tubes are the consumables
● X-rays are emitted by refraction
 
3. New type closed source (marketed as “NT” ray source)
● Not so expensive
● The life span of the tube life will be about 5000 hours. After that, the tube should be replaced with the new one.
● As the tube ages, its focus will increase followed by the blurring of the image
● Here, sources are the consumables for users. Filaments should be changed for manufacturers.
● X-rays get emitted by the transmission

X-ray inspection systems for auto parts are divided into two categories. The inspection systems may be 2D or 3D, which may be operated either online or offline. Let us go through them in detail:
 
● 2D X-ray inspection system:
It shows the two-dimensional images from both sides of the auto parts at the same time, thereby delivering a clear picture of the board’s components. This mechanism is similar to the traditional medical X-ray, which was used to view the bone fractures. These 2D systems can be operated either online or offline.
 
● 3D X-ray inspection system:
It creates the three-dimensional image of an auto parts by forming a series of 2D cross-sections. This mechanism is similar to the CT scan used in the medical industry. This system also works using the tomography method, where it combines the cross-sections and eliminates the images from other sections to build up a specific area precisely. The CT method of the 3D system can only work offline due to its complex algorithms. But the tomography method can be used both online and offline.
 
● Online X-ray inspection system:
Several X-ray devices are used online for data collection and comparison. Most of these devices are put after the reflow oven. Hence, it will be easier to process enormous quantities of complex auto parts, based on the additional cost and safety elements. However, the online operations will slow down the efficiency of the X-ray machine, thereby consuming more time and expenses. It is the slowest part of the assembly line, where the ability of the fabrication line becomes low.
 
Offline X-ray inspection system:
All types of X-ray devices can be operated offline to achieve panel inspection and sampling inspection. This operation type is comparatively quick to run. It is possible to inspect auto parts conveniently at any stage in the assembly line. Hence, it is less cost-effective with higher productivity.
 
Selecting the perfect system for your operation must be done carefully. Opting for a 2D or 3D system with online or offline abilities usually depends on the measure of the target product inspected, the expected quality of the inspection, as well as the quantity of time required to complete the inspection process.
 
The X-ray inspection system with CT function is usually operated offline due to the requirement of more 2D images and complicated algorithms. Hence, this CT X-ray inspection system is used only in the less significant professional research areas. Other 2D and 3D systems were instructed with the best image at the least time in order to cut the cost of the inspection.

The major parameters of an automotive X-ray inspection machine include:
 
1. Magnification
● Geometric magnification, with the optical magnification
● The total magnification that can enlarge the photo digitally via the computer, followed by an in-depth observation.
2. Manipulator
● Anti-collision design
● The more the shafts, the better will be the precision
● 360-degree plane rotation
● Sample holder
3. Radiation protection to prevent leakage
● As per the international standards, the permissible level of radiation leakage will be less than 1µSv/hr.  

Automobile Engine Hood
 
This magnesium alloy has been developed as many automobile parts such as steering wheel frame, transmission case, seat frame, wheel hub, instrument panel frame, etc. by engine factories and parts suppliers nationally and internationally. How should we ensure the quality of magnesium alloy parts then? This is where X-ray based nondestructive testing machines play a significant role.
 
X-ray based non-destructive testing equipment can be conveniently used to detect magnesium alloy parts, for any defects at a glance via real-time imaging. It can get connected with the production line of the factory, implement the complete automatic loading and unloading manipulator, decrease the manpower cost, understand the integration method of production, testing, and evaluation thereby improving the production efficiency. With maximum resolution, high definition qualitative imaging, automatic defect recognition, and the automatic evaluation function, this entire system can inspect the magnesium alloy parts automatically and thoroughly with 100% accuracy in real-time.

Highly qualitative fluoroscopic images can be emitted using a non-destructive X-ray inspection device that converts the signals received by a flat-panel detector. The entire functioning can be carried out with the help of a mouse. This system is quite easy to use. Standard high-performance X-ray sources can inspect defects below 5 microns, and the system can magnify up to 1000 times, by tilting the object in any direction. The associated software can automatically or manually detect the test object and generate a detection data report.
 
The features of industrial flaw detector include:
 
1. Maintenance-free sealed tube-type micro focus X-ray source
 
2. Sports full-time stocked with step drive and ball screw to promote characteristics such as more stability, low noise, high precision, etc.
 
3. High-voltage power supply with light integration to achieve more stable and reliable work
 
4. Automatic protection function of the lamp – after 20 minutes, there will be an automatic power cut, without any process safety phase.
 
5. Automatic protection function of the equipment – If anyone opens the door, the equipment will stop emitting X-rays at once, and reach the shutdown protection phase.
 
6. The function of angle tilt, automatic timing, as well as automatic navigation for the cumulate light tube’s utilization time.

The common defects in the castings include especially holes and inclusions. So, let us understand the differences between loose holes, slag, shrinkage holes, pinholes, and trachoma in the defect.

There are two categories of defects:
1. Inclusion type
2. Hole-type

Deficiencies such as slag and trachoma come under the inclusions category.

1. Slag: It occurs during the pouring process in the liquid metal in a timely manner without separation

2. Trachoma: If the sand debris gets entrained in the liquid metal, trachoma is formed. Due to the sand formation, it remains in the liquid metal into the cavity before it already exists during individual pouring.

Deficiencies such as loosening, shrinkage, and pinhole come under hole-type defects (i.e., no inclusions in this defect).

1. Loosening: It is officially called as shrinkage – a honeycomb defect due to inadequate shrinkage during the liquid metal solidification step.

2. Shrinkage hole: This defect is more serious, where the hole is usually accompanied by the upper part of the shrinkage area. It gets concentrated into one or several larger holes.

3. Pinhole: As per the formation mechanism, it is divided into many types. At times, slag porosity phenomenon may take place due to the slag or sand containing gas material formation.

The quality of the castings typically includes internal quality, external quality, and service quality.
 
● External quality– refers to the roughness of the casting surface, shape deviation, size deviation, weight deviation, and defects.
 
● Internal quality– refers to the mechanical properties, physical properties, chemical composition of the casting, metallurgical organization along with the internal defects such as the presence of cracks, holes, inclusions, segregation, and other conditions within the casting.
 
● Service quality– refers to the strength of the castings in varied conditions, including corrosion resistance, wear resistance, heat and cold resistance, shock absorption, fatigue, and other properties like weldability, machinability, and other technological properties.
 
Varied inspection methods including X-ray, γ-ray, eddy current and ultrasound can check and determine the internal quality of the castings. With the help of the ray detection effect, it’s possible to predict the size, shape, type, and distribution of internal defects in the castings.
