End To End

The reliability of ultrasonic testing (UT) of the quality of welded joints of polyethylene pipelines, made end-to-end with a heated tool, is considered in comparison with mechanical tests and radiography. The greatest detection of solid defects is provided by ultrasonic inspection with the use of chord tipe probes (not less than 90 %). When detecting defects translucent for ultrasound (lack of penetration, lack of fusion, etc.), the reliability decreases to 70÷80 %.

Arc Welding Process

The analysis of the electric arc welding process is performed. The main types and causes of defects in welded joints have been identified. The main non-destructive methods of control of welded joints are analyzed. The revealed advantages and disadvantages of each method. The method of ultrasonic testing is considered in sufficient detail. Shown on the practical experience of ultrasonic inspection of welded joints by a flaw detector with antenna arrays. The features of application of the program for PC «USD-soft», which allows automating the control of welded seams, are considered.
