Hawking welding stress relief equipment
|
|
Hawking welding stress relief equipment is Huawin
introduction of Ukraine’s military technology,and
access to national patent in China.
|
|
The advantages Hawking welding stress relief
equipment:
|
|
It's the best aging method that can completely
eliminate the welding residual stress and produce
the 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).
|
|
Fatigue strength of welding joints increased
*****0%,fatigue life extended ****0
times.corrosion resistance increased about **0%
in corrosive enviroments.
|
|
It’s can complete 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 aging method can be used without
considering the material,shape,struture,plate
thickness,weight,place,especially easy to use at
the construction site,the welding process and
welding repair to eliminate the welding stress.
|
|
Can make the remain height,pits,undercut into
Arc,and reduce the stress concentration factor.
|
|
Can eliminate the micro-cracks and slag defects
of weld-toe,inhibiting the advanced initiation of
crack.
|
|
As Hawking eliminating stress treatment can also
improve the several factors of weld fatigue,for
example,residual stress,micro-crack,weld toe
geometry and surface hardening,so the Hawking
aging method is the best way to improve the
fatigue of weld toe,it’s the multiplier way.
|
|
Especially for the large-scale structure of the
eliminating the stress treatment,for example,the
site weld,high or low at the weld and repairing
the weld seam.
|
|
Environmental protection,energy
saving,safety,noe-polluting,and very easy to use
at the constuction site.
