我们用国产LM-150型自动对接焊机对φ32毫米和φ36毫米钢筋的闪光对接焊进行了半年多的试验研究。通过1600多对接头的试焊、分析,确定了工艺和有关参数,并在此基础上制订了施工操作规程。我们按这一工艺和有关参数,应用到几座装配式钢筋混凝土桥的φ32毫米和φ36毫米钢筋的对焊工程中,按照国家规定进行检验,全部合格。现将我们对这一工 We used the domestic LM-150 automatic butt welder to perform flash butt welding on φ32 mm and φ36 mm steel bars for more than six months. Through the welding and analysis of more than 1600 pairs of joints, the process and related parameters were determined, and on this basis, the construction operating rules were formulated. Based on this process and related parameters, we applied the φ32 mm and φ36 mm steel bars of several assembled reinforced concrete bridges in the butt welding works and inspected them according to the national regulations. All were qualified. Now we will work on this
