    • The present invention relates to an improvement method for the rigidity of piston heads to adapt to high output power engines, and an apparatus to realize the method. The method comprises: a preheating process (S10) to preheat the piston head (1); a setting process (S20) to tilt the center axis (C) of the piston head (1) at a first angle (A1) by tilting the piston head (1) at the first angle (A1) with respect to a vertical axis (V) so that the corners (5) thereof face upward; a partial melting process wherein a rim part (7) is made to repeat melting and solidification by applying high heat to the rim part (7) using a TIG welder while rotating the piston head (1) around the center axis (C) as an axis; and a cooling process to cool the piston head (1). [Reference numerals] (S10) Preheating process; (S20) Setting process; (S30) Partial melting process; (S31) Main melting section; (S32) Overlap section; (S33) Slope down section; (S40) Cooling process; (S50) Discharge
    • 本发明涉及一种用于适应高输出功率发动机的活塞头的刚度的改进方法以及实现该方法的装置。 该方法包括:预热活塞头(1)的预热过程(S10) 通过相对于垂直轴线以第一角度(A1)倾斜活塞头(1),使活塞头(1)的中心轴线(C)倾斜第一角度(A1)的设定处理(S20) V),使得其拐角(5)面向上; 部分熔融方法,其中通过使用TIG焊机将活塞头(1)围绕中心轴线(C)旋转,同时通过将高热量施加到轮辋部分(7),使轮辋部分(7)重复熔融和凝固,作为 轴; 以及冷却活塞头(1)的冷却过程。 (附图标记)(S10)预热处理; (S20)设定处理; (S30)部分熔融工艺; (S31)主熔段; (S32)重叠部分; (S33)斜坡段; (S40)冷却过程; (S50)放电
