Hawking welding stress relief equipment

Hawking welding stress relieving equipment
principle is use the high-power frequency tool to impact the metal
surface as per twenty thousand times per second,to 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 shock wave change the original stress field and
creat a certain number of hitting stress,and strengthen the
impacted site.
The advantages of 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 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.
