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 type of reaction does a dental material undergo when distortion occurs?
Restorative and esthetic dental reaction occurs when a dental material undergoes distortion.
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.
What type of distortion always occurs on an analog connection?
White Noise
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
What happens when the curves of a globe become straight lines on a map?
distortion of a size, shape, distance, or area occurs.
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.
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 is aperture distortion?
Aperture distortion, also known as lens distortion or optical distortion, refers to the various aberrations or imperfections that can occur in photographs due to the characteristics of the camera lens and its aperture (the opening through which light enters the camera). These distortions can manifest in different ways: Barrel Distortion: This type of distortion causes straight lines to appear curved outward, resembling the shape of a barrel. It typically occurs with wide-angle lenses and can make objects at the edges of the frame appear stretched or bulging. Pincushion Distortion: Pincushion distortion is the opposite of barrel distortion. It causes straight lines to curve inward, like the shape of a pincushion. This distortion is more common in telephoto lenses. Chromatic Aberration: This type of distortion occurs when different wavelengths of light do not converge at the same point, resulting in color fringing, especially at high-contrast edges in an image. Vignetting: Vignetting causes the corners or edges of an image to be darker than the center. It happens when the aperture is not evenly transmitting light across the entire frame. Spherical Aberration: Spherical aberration can cause blurriness or softness in an image, particularly around the edges, due to the way light rays are bent by the lens elements. Distortion from Aperture Shape: The shape of the aperture itself (e.g., circular, hexagonal) can impact the appearance of out-of-focus highlights or "bokeh" in the background of a photograph. Photographers often aim to correct or minimize these distortions through lens design, post-processing techniques, or by choosing lenses suited to their specific needs.
What is temporal distortion?
A temporal distortion occurs when 2 dimensions interact with one another, the observer may be able to catch a fleeting glance into 'another world'. A good example of a temporal distortion are ghosts. Ghosts are perceived as visitations from the afterlife where as all it is, is 2 dimensions existing simultaneously and temporarily coexisting. Man is indeed capable of creating a temporal distortion which can be induced using ancient mystical school teachings and more commonly, hallucinogens.
Does showing the round earth on flat maps distort some images?
The proof that distortion occurs is to peel an orange in one piece, and then flatten the skin.
Moving information from a curved surface to a flat surface causes?
When information is moved from a curved surface( like the Earth) to a flat surface ( like a map), distortion occurs.
