Things to Know About Ultrasonic Testing

Ultrasonic testing is a common and well-known method for the non-destructive testing of welding materials. One of the most significant advantages of this technology is that it has no negative consequences for the operators. According to the welding inspectors in Brunie, the ultrasonic testing find internal discontinuities using mechanical vibrations in the form of ultrasonic waves. The technology has been utilised in several engineering industries since the 1950s and is now well-established. In this blog, we are going to discuss major things to know about ultrasonic testing.

Why is ultrasonic inspection used?
The ultrasonic inspection process is mainly to detect the following defects:

• Cracks in the weld zone
• Pores
• Lack of fusion
• Weld metal stratification
• Discontinuities & improper fusion of weld joints;
• Slack metal in the weld lower zone
• Corrosion
• Chemical composition discontinuity
• Geometric size distortion

What to consider for this inspection?
Ultrasonic welding inspection is kind of a complex process requiring qualified and well-trained welding inspectors. Several factors need to be considered before the inspection can be carried out. They include:

•Ultrasound physics (Propagation, waves modes, reflection, attenuation, mode conversions, etc.)
•Transducer operation, characteristics and theory (Radiated field, piezoelectric effect, energy loss, beam spread, etc.)
•Equipment operation (Receiver, data presentation, etc)
•Ultrasonic testing testings (Through Transmission, Pulse-Echo, Pitch-Catch, etc.)
•Specific requirements (Weld type, dimensions, shape and surface quality)
•Equipment calibration & evaluation techniques (AWS, DAC, DGS, etc.)

Benefits of ultrasonic testing
Ultrasonic testing is a powerful and highly efficient inspection procedure. It has a number of industrial benefits, such as:

• High sensitivity to subsurface and surface discontinuities
• High penetration depth in comparison to other NDT methods
• High accuracy rate in determining the discontinuity position & estimating its shape and size
• Minimal part preparation
• Digital equipment offers instant results
• In addition to flaw detection, thickness measurement is performed

The importance of ultrasonic welding inspection is huge. This is essential that NDT specialists or welding inspectors who perform an ultrasonic inspection of weld materials should have proper certification and training. The international welding standard (ISO 9712:2012 – certification and qualification of NDT personnel) determines the criteria. Not only the NDT operator or inspector should be qualified to perform the ultrasonic inspection process, the inspection equipment, procedure, evaluation method and calibration test blocks are also regulated by an adequate set of industry standards

4×4 Vehicle General Check-Ups & Maintenance Tips

A 4×4 vehicle is built with high traction power that allows driving on rough terrains such as icy roads, rocky areas, wet roads and off-roads. The 4WD system is one of the modern technologies used in several types of cars and trucks today. However, due to a lack of maintenance and general repairs, the 4WD systems can start showing unwanted behaviours. A 4WD vehicle contains too many components. According to expert mechanics in Mooroolbark, 4WD components always need basic maintenance services to keep the vehicle functional & long-lasting. Essential general repair services include

• Clean and check all 4WD components
• Lubricate the locking hubs properly
• Transfer case inspection
• Drain out differential fluids & refill it

Other maintenance services include:

Inspection
4WD vehicles contain several components & sub-components that enable the 4WD engine to generate high power to build maximum traction. Major parts include differential, hubs, transfer cases, etc. Professional inspection & maintenance service can identify potential problems in the 4WD vehicle. Experts can fix initial problems very easily.

Lubrication
Checking or maintaining the lubrication and fluid level of the 4WD cars is essential. This is because lubrication loss causes expensive damage.

Leak checks
Any minor leak in the 4WD engine should be inspected as early as possible. Repairing the minor leaks will prevent an expensive repair or replacement of a 4WD vehicle.

Transfer case
The transfer case of a 4WD vehicle mainly takes the power of the engine from the transmission system & routes to the front and rear differentials. Nowadays, these units are used in both 4WD & AWD vehicle systems. The transfer case should be inspected to keep it functional for a long time.

Hub Service
Hubs are mainly used in the 4WD systems for transforming them into vehicle wheels, offering the ultimate traction power & grip in the vehicle & improved fuel economy. Professional mechanics in Mooroolbark will accurately inspect & restore the locking hubs.

Other services
Trusted car workshops also offer additional 4WD repair and general maintenance services at the lowest price. Professional mechanics and technicians can inspect different kinds of 4WD problems occurring due to lack of maintenance:

• Suspension problems
• Tire & wheel damage
• Worn-out braking systems
• Broken steering gear

Periodic maintenance and general checkups both are extremely essential to keep the 4WD system functional as well as long-lasting. Proper diagnostics & maintenance services will fix all the 4WD related issues efficiently.
