摘　　要：12CrMoV珠光体耐热钢顶杆在制作过程中,采用V型坡口焊条电弧焊、水平固定全位置对接接头焊接,焊接性差,焊接难度大,通过规范焊接工艺和焊接质量控制,有效避免了未焊透、夹渣、裂纹等缺陷,保证了焊接质量。In the production process of 12CrMoV pearlitic heat resistant steel carrier rod,there are such problems as poor weldability and great welding difficulty caused by using the v-groove electrode arc welding and horizontal fixed all position butt joint welding,such defects as incomplete penetration,slag inclusion and cracks are effectively avoided by standardizing the welding process and welding quality control to ensure the welding quality.

关 键 词：珠光体耐热钢 夹渣 裂纹
