1、A Study on Side Defects of Hot Rolled Q235B and Q345B Strip Steels;
2、Welding Application of Auto Submerged Arc Welding Technique in the Boiler and the Pressure Vessel Tube Body(Q235B,δ=6mm)
3、The surface defect on medium and heavy plate Q235B was investigated by means of the optical microscopy, scanning electron microscopy and energy spectrum analysis in this paper.
4、In this paper, it was studied to improve the fatigue strength of welded joints and structrures of low carbon steel Q235B by peening the welded toes with ultrasonic equipment.
5、Ultrasonic fatigue tests were carried out on Q235B base metal and welded joints by an ultrasonic fatigue test equipment in order to investigate their super high cycle fatigue properties.
6、用超声疲劳试验装置对Q235B母材及焊接接头试件进行超声疲劳试验，研究其在超高周疲劳寿命区间的疲劳*能。
