stress relieving equipment

Hawking welding stress relief equipmentpricinple:
Hawking welding stress relieving equipmentprinciple is use the high-power frequency tool to impact the metalsurface as per twenty thousand times per second,to make the metalsurface a great plastic deformation due to hawking highfrequency,high efficiency and high energy under focus.at the sametime,the hawking shock wave change the original stress field andcreat a certain number of hitting stress,and strengthen theimpacted site.

The advantages of Hawking welding stress reliefequipment:
It’s the best aging method that cancompletely eliminate the welding residual stress and produce theideal hitting stress(others aging methods to eliminate the residualstress of the situation as follows:30-50% of VSR,40-80% heataging,80-10% hawking aging).
Fatigue strength of welding joints increased 50-120%,fatigue lifeextended 5-100 times.corrosion resistance increased about 400% incorrosive enviroments.
It can complete replace the heat aging and VSR aging,the processsimple and the result is stable and reliable(it can be usedeverywhere,everytime,every process,vert easy to use)
Hawking aging method can be used without considering thematerial,shape,struture,plate thickness,weight,place,especiallyeasy to use at the construction site,the welding process andwelding repair to eliminate the welding stress.
Can make the remain height,pits,undercut into Arc,and reduce thestress concentration factor.
Can eliminate the micro-cracks and slag defects ofweld-toe,inhibiting the advanced initiation of crack.
As Hawking eliminating stress treatment can also improve theseveral factors of weld fatigue,for example,residualstress,micro-crack,weld toe geometry and surface hardening,so theHawking aging method is the best way to improve the fatigue of weldtoe,it’s the multiplier way.
Especially for the large-scale structure of the eliminating thestress treatment,for example,the site weld,high or low at the weldand repairing the weld seam.
Environmental protection,energy saving,safety,noe-polluting,andvery easy to use at the constuction site.
