英文
spot melting welder-
Dark red flake, melting point 197 ` c, easily deliquescent, soluble in water poisonous, corrosive and flammable with the organic
呈紅色片狀物，熔點197 ` c ，極易溶解，易溶於水，有毒，腐蝕性強，與有機物接觸可引起燃燒。Due to two work states - - - arc burning and short current - - - existed in welding process of consumable electrode welding, and different control objectives in these two states, two close - loop feedbacks are designed in the control system : welding voltage feedback and welding current change rate feedback
根據熔化極co2焊機具有燃弧和短路兩種工作狀態，且兩種狀態下控制目標不同的特點，在控制系統中設計了雙閉環反饋：焊接電壓反饋及焊接電流變化率di / dt反饋。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 - 14As an important branch of rapid prototyping ( rp ), direct laser metal sintering ( dlms ) is used for manufacturing metal parts by scanning metal powder based on the process of selective laser sintering ( sls )
