This Tensile Residual Stress.
The residual stress is mainly due to the large temperature gradient in the molten pool.
By heat treatment Release residual stress;
Remove residual stresses in the part.
In the process of metal laser 3D printing,high residual stress is generated.
Therefore, residual stresses are low in a finished weld.
This mixture is poured into moulds, hardened andthen processed to reduce residual stress.
(3) Large welding residual stress and residual deformation cannot be produced.
When the transformer is subjected to shock and vibration,these external forces superimpose the residual stress of the weld.
Welding residual stress is another major cause of oil leakage in transformer welds.
The effect of heating temperature andholding time on the residual stress of TC4 titanium tube and titanium alloy.
To remove the residual stress, a little shake hands, and the hands are rotated in a clockwise direction and vice versa.
Hydrostatic testing machine is mainly used to make a pressure test on the steel pipe and eliminate residual stress.
Although the residual stress is self-phase equilibrium, it still has some influence on the performance of steel members under the action of external force.
Once it exceeds its fatigue strength,cracks will occur at the peak region of the residual stress and not through the weld defect.
The main methods of residual stress are: 1 adjusting the processing technology, controlling the size of the molten pool, so that the heat can be dissipated faster;
It can also be used for surface matting,descaling and eliminating residual stress of casting, forging and weldments.
The residual stress is the internal self-phase equilibrium stress without external force, andthe hot rolled section steel with all kinds of sections has this kind of residual stress.
Initially observed micron-scalepores are the main cause of fatigue strength, where residual stress increases fatigue crack growth.
In the process of metal laser 3D printing,high residual stress will be generated, and the stress deformation and cracking of complex structure parts during forming are always the biggest challenges faced by metal 3D printing.
Its defect is easy to deformation,this is because the steel after processing, the residual stress inside the release lead to deformation.
This, the mechanical expansion ratio is preferably from 0.5 to 1.5% under the condition that a predetermined steel pipe roundness can be obtained and the residual stress can be removed.
The cause of the stress corrosion cracking is mainly the welding stress, especially the stress source caused by the residual stress caused by the repair welding and the structural stress generated during the manufacture of the equipment.
Comparative analysis of BaF2 epitaxial growth on Si(111) and on CaF2(111)/Si(111) was carried out. It was established that epitaxy of BaF2 directly on Si(111)without intermediate layer CaF2 occurred by a layered growth mechanism leading to residual stress reduction and to surface morphology improving.
Aging treatment can be divided into natural and artificial ageing two natural aging is the casting is placed in the open area for more than half a year,then slowly occurs, thereby the residual stress eliminating or reducing artificial aging is heated casting to 550 to 650 DEG C for stress relief annealing, it than natural aging save time,residual stress could be removed more thoroughly.
Welding process must be in accordance with the order of the construction,4 can not produce a large welding residual stress and residual deformation.
The main factors affecting the two are the thickness andmaterial of the workpiece, the original residual stress, and the final degree of stress relaxation.
The purpose of the copper plate pre-feeding baking plate(150 degrees Celsius, time 8±2 hours) is to remove the moisture in the plate, and at the same time completely cure the resin in the plate,further eliminating the residual stress in the plate, which is to prevent the plate from being warped.
After seam welding of the jointing parts,the pipe is processed for mechanical expansion for the purpose of removing the weld ing residual stress and improving the steel pipe roundness. In.
Nondestructive testing: studies and research by means of the neuronal networks and of the phase logic, methodologies andequipment to determine the residual stresses during welding using the US and Barkhausen methods;
