The welding technology of francis turbine runners is optimized from the view of subsection welding and local heating by numerical simulation. the result shows that welding residual tensile stress appears in the weld and its area nearby, and peak stress appears in the dangerous area of blades after practising quondam welding technology ; welding residual tensile peak stress in the dangerous area of blades can be decreased by welding both ends earlier and then welding middle section later during subsection welding, and decreasing effect on welding residual stress of the subsection welding is related to the weld length of blade outlets and welding direction of each subsection ; decreasing effect on residual stress of the local heating is direct proportional to heating time, heating temperature, heating area, and inversely proportional to cooling area, and welding residual tensile peak stress in the dangerous area is decreasing trend earlier, and then increasing trend later with heated location increased
本文利用數值模擬手段對轉輪的焊接工藝從分段焊和局部加熱兩個方面進行了優化,結果表明:採用普通工藝焊接時,葉片焊后殘余拉應力出現在焊縫及其附近區域,並且在葉片出水邊的熔合線附近(危險區域)出現了峰值;在採用優化的分段焊時,先焊兩端后焊中間的方法可以降低葉片危險區域的焊接殘余拉應力峰值,降低效果與葉片出水邊焊段長度、焊縫各段的焊接方向有關;局部加熱法降低轉輪危險區域殘余應力的效果主要與加熱時間、加熱溫度以及加熱面積成正比,與冷卻面積成反比,並且危險區域的殘余應力隨加熱區域的增大呈先降低后升高的趨勢。Solder bar is made from high purity metal. by means of strict qualitg control the oxide and metallic and non - metallic impnrities and effectively minimized, the available high purity solder bar is with uniform and glazed surface good wetting and spreading ability after molten bright joint and minimum oxide residue after soldering. our product is suitable for wave and handwork soldering with high quality requirement
本公司生產焊錫條採用高純度金屬原料,在嚴格品管條件下,有效控制氧化程度以及金屬和非金屬雜質含量,焊錫條表面均勻光滑,純度極高,熔化后流動性好,潤濕性極佳,焊點光亮,氧化渣物極少發生,適用於高品質要求的各種波峰焊和手工焊。Ultrasonic plastic welding theory is generated by the generator 20khz or 15khz pressure, high - frequency signals, the system can be adopted for the high - frequency signals into mechanical vibrations, and in plastic products working, through working surface and internal friction among elements spread by the department of the interface temperature, when the temperature reached the melting point of her own, that the working interface rapid melting, and then fill in the gaps between the interfaces when shock stop working at a certain pressure and cooling will be a perfect welding
的高壓高頻信號通過換能系統,把信號轉換為高頻機械振動,加於塑料製品工件上,通過工件表面及內在分子間的磨擦而使傳處到介面的溫度升高,當溫度達到此工件本身的熔點時,使工作介面迅速溶化,繼而填充于介面間的空隙,當震動停止,工件同時在一定的壓力下冷卻定形成完美的焊接.點擊數: 723錄入時間: 2006 - 5 - 14Surface layer welding
