钢筋电渣压力焊连接技术,适用于竖向钢筋或倾斜度在4:1范围内的钢筋焊接。和电弧焊、气压焊等钢筋连接技术相比,它具有节约钢材、施工方便、工效高、成本低等优点,因此,在竖向粗钢筋(直径为14～40mm)连接中应用广泛。一、接头断裂的定义和类型1.定义一些电渣压力焊接头在质量检查中并未出现《钢筋焊接及验收规程》中所规纳的8种外观质量缺陷,但却通不过焊件拉伸试验,且都在接头横截面上断裂,这种断裂称为接头断裂,实为未焊合。
Reinforced electro-slag pressure welding connection technology, suitable for steel reinforcement with vertical reinforcement or inclination in the range of 4: 1. Compared with reinforced connection technology such as arc welding and air pressure welding, it has the advantages of saving steel, convenient construction, high work efficiency and low cost. Therefore, it is widely used in the connection of vertical crude steel (diameter 14 ~ 40mm). First, the definition and type of joint rupture 1. Definition Some electroslag pressure welded joints did not appear in the quality inspection of the “steel welding and acceptance of the rules” in the eight kinds of appearance quality defects, but pass welding tensile Test, and both in the joint cross-section fracture, this fracture is called joint fracture, it is not welding.
