浅谈用超声波探伤钢网架球管焊缝

Talking about Ultrasonic Detection of Welding Seams on Ball and Tube of Space Frame

指出对空间钢网架球管焊缝进行超声波探伤,检测结果表明;超声波探伤完全能保证控制焊缝质量,并对裂纹、根部未焊透等缺陷有较高的检出率和较高的可靠性。

This text deals with ultrasonic detection of welding seams on ball and tube of space frame. The detecting results prove that ultrasonic detdction of welding seam can assure good welding quality and is highly efficient and reliable to find cracks and defects of lack of penetration.
