Distortion or deformation can occur during welding as a result of the non-uniform expansion and contraction of the weld and base metal during the heating and cooling cycle.Stresses form in the weld as a result of the changes in volume, particularly if the weld is restrained by the fixed components or other materials surrounding it. If the restraints are partly removed, these stresses can cause the base material to distort and may even result in tears or fractures. Of course, distortion can be very costly to correct, so prevention is important. .here are various types of distortion and dimensional change including longitudinal; transverse; angular; twisting and bowing. Two or more types of distortion may occur at the same time

What is Attenuation distortion in networking?
Attenuation distortion is the distortion of an analog signal that occurs during transmission when the transmission medium does not have a flat frequency response across the bandwidth of the medium.
Which type of distortion occurs when a connection cable is inadequately insulated?
Impulse noise
The distortion of enzyme molecules which occurs at high temperatures is known as?
Denatured
A change in the accuracy of shapes and distances on a map is called?
A change in the accuracy of shapes and distances on a map is called distortion. Distortion occurs because it is impossible to represent the Earth's curved surface on a flat map without some degree of distortion in shape, size, or distance.
What is the relationship between pincushion distortion and barrel distortion, and how do they differ from each other?
Pincushion distortion and barrel distortion are both types of optical distortions that occur in images. Pincushion distortion causes the image to appear pinched inwards towards the center, while barrel distortion causes the image to bulge outwards towards the edges. The main difference between the two is the direction in which the distortion occurs - pincushion towards the center, and barrel towards the edges.
What happens when the curves of a globe become straight lines on a map?
distortion of a size, shape, distance, or area occurs.
What type of reaction does a dental material undergo when distortion occurs?
When distortion occurs in a dental material, it typically undergoes a physical or chemical reaction. Physical reactions involve changes in shape or size due to external forces, while chemical reactions involve bond breakage or formation due to exposure to certain substances or conditions. It's important to identify the type of reaction to determine appropriate corrective measures.
What is the meant by harmonic distortion in wave analyzers?
distortion refers to any deviation in any parameter like amplitude,time shape of an electrical signal from an ideal input signal.the distortion occurs due to the inherent non-linear characteristics of the component and devices that form the electronic circuit cause some harmonics to take place in the waveform and resultant deviation is know as harmonic distortion.
Where is the smallest distortion in an azimuthal projection?
In an azimuthal projection, the smallest distortion occurs at the center point of the projection, where the point is tangential to the surface of the Earth. As you move outward from this center point, distortion in scale, shape, and area increases. This projection is often used for polar regions, where the distortion is minimized at the poles. Thus, the central point is the most accurate representation in terms of distance and direction.
What happens when a curved surface is transferred to a flat map?
When a curved surface, such as the Earth's surface, is transferred to a flat map, distortion occurs. This distortion can affect the shape, size, distance, and direction of features on the map, known as map projection. Different map projections are used to minimize these distortions for specific purposes.
In which amplifier occurs Maximum distortion?
CLASS -C amplifier is having high ditortion due to which they are not used in audio frequency work
What type of map doesn't show distortion?
A type of map that doesn't show distortion is a globe. A globe is a three-dimensional representation of Earth, which accurately depicts the true shapes and sizes of continents and oceans without distortion that occurs on flat maps.
