ANGLE BEAM IN ULTRASONIC INSPECTION.

Angle Beam 1:- Angle Beam Transducers and wedges are typically used to introduce a refrected shear wave into the test material. An angled sound path allows, the sound beam come in from the side,thereby improving detectability of flaws in and around welded areas.
Angle Beam 2:- Angle beam transducers and wedges are typically used to introduce a refrected shear wave into the test material. The geometry of the sample below allows the sound beam to be reflected from the back wall to improve detectability of flaws in and around welded areas.

The Technical Aspects of Modern Cars: Understanding How Your Vehicle Works

Image
Host : Welcome to our show, where we bring you the latest news and updates on cars and their technical aspects. Today, we're going to take a closer look at the various technical aspects of modern cars and how they work. First, let's talk about the engine. The engine is the power source that drives the car and propels it forward. A modern engine is a complex piece of machinery that is made up of various components such as the pistons, crankshaft, camshaft, and valves. The engine works by burning fuel in the combustion chamber, which generates heat and energy. This energy is then used to turn the crankshaft, which in turn rotates the wheels of the car. Next, let's talk about the transmission. The transmission is responsible for transferring the power generated by the engine to the wheels of the car. There are two main types of transmissions - manual and automatic. In a manual transmission, the driver changes gears by using a clutch pedal and a gear lever, while in...

BASIC PRINCIPLES OF MAGNETIC PARTICLE TESTING.

Image
In the theory, magnetic particle inspection (MPI) is a relatively simple concept. It can be considered as a combination of two nondestructive testing methods: magnetic flux leakage testing and visual testing. Consider the case of a bar magnet. It has a magnetic field in and around the magnet. Any place that a magnetic line of force exits or enters the magnet is called a pole. A pole where a magnetic line of force exits the magnetic is called a north pole and a pole where a line of force enters the magnet is called a south pole. When a bar magnet is broken in the center of its length, two complete bar magnet with magnetic poles on each end of each piece will result. If the magnetic is just cracked but not broken completely in two, a north and south pole will form at each edge of the crack. The magnetic field exits the north pole and reenters at the south pole. The magnetic field spreads out when it encounters the small air gap created by crack because the air cannot support as much ...

WELDMENTS ( welded joints) in ultrasonic inspection.

Image
The most commonly occurring defects in welded joints are porosity, Slag inclusions, lack of side - wall fusion, lack of inter - run fusion, lack of  root penetration, undercutting, and longitudinal or transverse cracks. With the exception of signal gas pores all the defects listed are usually well detectable by ultrasonic. Most applications are on low-alloy construction quality steels,however, world's in aluminium can also be tested. Ultrasonic flaw detection has long been the preferred method for nondestructive testing in welding application. This safe,accurate, and simple technique has pushed ultrasonics to the forefront of inspection technology. Ultrasonic weld inspections are typically performed using a straight beam transducer in conjunction with an angle beam transducer and wedge. A straight beam transducer, producing a longitudinal wave at normal incident into the test piece, is first used to locate any laminations in important because an angle beam transducer may not a...
