一、前言现在工厂用高硬度薄板制造的结构采用奥氏体焊条手工电弧焊,成本较高,而且焊接质量受到操作等因素影响较大。因而,拟采用混合气体保护焊工艺。该产品
I. INTRODUCTION Nowadays, the structure of the factory made of high hardness thin plate adopts the manual arc welding of austenite electrode, the cost is high, and the welding quality is greatly influenced by the operation and other factors. Therefore, the proposed hybrid gas shielded welding process. this product
