Safety parts within the automotive industry, such as the treated transmission element of the steering mechanism, are subject to the most severe conditions and controls within the production process.
汽車工業(yè)中的安全部件，例如轉(zhuǎn)向裝置中經(jīng)處理的傳動元件，在生產(chǎn)過程中經(jīng)受最劇烈的條件和嚴(yán)格的控制
To meet these conditions, the nondestructive ultrasonic inspection for the detection of flaws due to the die-forming has been envisaged among other methods.
為了滿足這些條件，因模具成型在眾多無損檢測方法中超聲波無損檢測已經(jīng)在考慮當(dāng)中
Typical flaws include overfoldings and cracks which are only seldom visually recognizable on the surface.
像典型的折疊和裂紋缺陷在表面上目視檢測很難檢測到。
SOLUTION:方案

Because of the defined flaw area, scanning in a fixed probe position is sufficient for the flaw detection using the H5K probe's large sound beam which is additionally expanded by being reflected from the curved backwall.
對于限定區(qū)域的缺陷檢測，H5K探具有較大的聲束寬度，被曲面反射后有更進(jìn)一步的聲束擴散，所以用H5K探頭在一個固定的位置足夠?qū)θ毕葸M(jìn)行檢測。
The component analysis is carried out by evaluating the flaw indications between the interface echo at sound entry and the indications from the geometry, such as edges – openings – holes.
通過對界面回波和幾何回形狀回波之間的回波信號評估來分析產(chǎn)品部件，例如工件邊緣回波，開孔之類的回波是來自幾何形狀回波。
