The principle of Hawking
equipment of eliminate welding stress:
The principle of Hawking
equipment of eliminate welding stress is to use the high-power frequency tool to
impact the metal surface as per twenty thousand times per second
and make the metal surface a great plastic deformation due to
hawking high frequency,high efficiency and high energy under
focus.at the same time,the hawking vibration wave change the
original stress field and creat a certain number of hitting
stress,and the impacted site will be strengthened.
The principle of Hawking
equipment to improve the fatigue strength and life of welded
point:
Use the
Hawking equipment to impact the weld toe,then make it become
compression deformation and smooth geometry transition,thus
reduce the weld toe over height and the stress greatly.it also
eliminate the micro crack and slag defects,and restrain the crack
initiation in advance.Ajust the weld residual stress
field,eliminate the pulling stress and creat hitting stress
around the weld toe,at the same time,make the toe part more
strengthened.Therefore,The hawking equipment eliminate the
residual stress and improve the several influence factors of
fatigue performance,for example,the toe geometry,residual
stress,micro crack , slag defects and surface strengthened,so it
will improve the weld toe’s fatigue strength and
life.
The advantages
ofHawking equipment
to eliminate welding stress:
It’s the method
that eliminate weld residual stress completely and creat ideal
hitting stress(others aging methods to eliminate the residual
stress of the situation as follows:****0% of VSR,****0% heat
aging,****0% hawking aging).
Improve the weld
strength *****0%,fatigue life ****0 times.corrosion resistance
**0% in corrosive enviroments.
It can completely
replace the heat aging and VSR aging,the process simple and the
result is stable and reliable(it can be used
everywhere,everytime,every process,vert easy to use)
Hawking method can
be used without considering the material,shape,struture,plate
thickness,weight,place,especially easy to use at the construction
site, to eliminate the welding stress while welding and
repairing.
Can eliminate the
micro cracks and slag defects of toe,restrain crack intiation in
advance.
Improve the several
influence factors of weld fatigue performence,for example,the
residual stress,micro crack, toe geometry and surface
strengthen.
It’s good for the
large structure especially,for example,the site,over height or
over low.
Environmental
protection,energy saving,safety, and very easy to use at the
construction sites.
