φ12钢筋电渣压力焊施焊技术与经济效益

Electroslag Pressure Welding Technique and Economic Effect of φ12 Reinforcing Steel Bar

钢筋电渣压力焊为我国1962年首创的一项施工技术,现在已经在全国获得广泛的应用。但是,当钢筋直径为12mm时,钢筋较细较软,焊接夹具夹挂后,钢筋容易弯曲,从而在接头中产生错位、气孔、夹渣等焊接缺陷。本文通过试验研究,提出适用于φ12钢筋电渣压力焊施焊技术和焊接参数,在陕西、河南、四川等省的多个工程中试用,接头质量合格,并取得良好的经济效益。

Electroslag pressure welding was a first inventive construction technology at 1962 in China and is used widely in our country now.When the diameter of reinforcing steel bar is 12mm,it is thinner and soft.The steel bar may be bended when welding apparatus is clamped.Therefore,some welding defects of misalignment,gas pore,slag inclusion may be appeared in the welding joints.In this paper,the electroslag pressure welding technology and welding parameters for 12mm diameter reinforcing steel bar are introduced,which was used in many construction engineerings in Shaanxi,He＇nan,Sichuan Provinces,and brought proper quality of joints and economic effect.
