Component and method for electrogas welding crack sensitivity test

The invention relates to a component and a method for electrogas welding crack sensitivity test, the component is a steel plate, the length of the steel plate is not less than 300mm, the width of the steel plate is not less than 250mm, a V-shaped groove is formed in the surface of the steel plate, and parameters related to the groove form are a groove truncated edge a, a groove root gap b and a groove angle alpha; and the thickness of the component is not less than 50mm. By adopting the method disclosed by the invention, the welding crack sensitivity of the steel plate during electrogas welding can be inspected, a reference is provided for formulating an electrogas welding process, and welding cracks during actual welding are avoided. 一种气电立焊焊接裂纹敏感性试验用构件及方法，所述构件为钢板，钢板长度不低于300mm，宽度不低于250mm，钢板表面打V型坡口，与坡口形式相关的参数为坡口钝边a、坡口根部间隙b、坡口角度α；构件厚度不小于50mm。采用本发明的方法可对钢板气电立焊焊接时的焊接裂纹敏感性进行检验，为气电立焊焊接工艺的制定提供参考，避免在实际焊接时出现焊接裂纹。
