The invention discloses a method for welding a metal beam column and a carbon fiber composite wall plate, a vehicle body structure and a railway vehicle before a tetragonal common commercial dense triangle is disclosed. The method comprises the following steps that the carbon fiber composite wall plate is placed on a metal supporting platform; the metal beam column is placed on the carbon fiber composite wallboard; and applying heat to the metal beam column by using the hot melting annular electrode, so that resistance heat is formed on the contact surface of the metal beam column and the carbon fiber composite wallboard, and the steel structure and the carbon fiber composite material are connected in a hot melting manner. Through mutual cooperation of the metal supporting platform and the hot melting electrode, perfect welding of the metal beam column and the carbon fiber composite wallboard is achieved. Through single-face hot melting connection, the excellent performance of the two materials is brought into full play, and the problem of welding marks on the surface of the exposed stainless steel wallboard is avoided.

    四方股份普通商密▲公开前本发明公开了一种金属梁柱和碳纤维复合墙板焊接的方法、车体结构及轨道车辆,如下:将碳纤维复合墙板放置在金属支撑平台上;将金属梁柱放置在碳纤维复合墙板;利用热熔环形电极在金属梁柱上施加热量,使得金属梁柱与碳纤维复合墙板接触面上形成电阻热,热熔连接钢结构和碳纤维复合材料。本发明通过金属支撑平台与热熔电极的相互配合,实现了金属梁柱和碳纤维复合墙板的完美焊接。本发明通过单面热熔连接,充分发挥了两种材料的优良性能,规避了外露不锈钢墙板表面的焊接痕迹问题。
