ilar conclusions in the research on QSTE340 steel welded tubes. A large number of studies show that welding caused a change in the hardness of the weld area. For example, in laser welding, the weld area hardness increased by 50%15 to 306 M. Zhan et al. Experimental and numerical studies on the prediction of Request PDF Experimental and numerical studies on the prediction of bendability limit of QSTE340 welded tube in NC bending process For a low carbon steel tube with small wall factor D/t and

The steel grades of the S315MC to S700MC series are used for cold-formed components of the most varied designs. The user of these steel grades must make sure that his calculation, design and processing methods are appropriate for the material. The forming process used must be suitable for the intended application and comply with the

Feb 10, 2021 · The material of the metal backrest is generally DC01, DC03 and QSTE340, and the thickness of the material is 0.5mm and 0.6mm. The metal backrest is connected with the frame by spot welding, which is generally used for the seat of the middle class vehicle. Numerical and Experimental Study of Forming Limit The paper establishes the forming limit diagrams (FLDs) for QSTE340 seamed tube hydroforming and the mother sheet metal forming by numerical approach and experimental approach. A novel experimental approach is proposed to evaluate the formability for tube hydroforming under biaxial stretching through elliptical bulging.Then the Nakazima and three types of tube hydroforming tests are simulated Q/BQB QStE 340 TM Q/BQB 310 - BBN STEEL STORESSteel, as we all know, offers great strength though it is light in weight. In fact, the ratio of strength to weight for steel is the lowest than any other building material available to us. Temperature

The welded tube NC bending tests were carried out to evaluate the weld on the formability of the QSTE340 welded tube. The results show that the wall thinning degree, cross-sectional deformation and springback angle increase significantly as the weld line is
