This book focuses on how to control welding deformation. The contents include the law of welding deformation and the calculation of welding bending deformation of beams and columns, the calculation of pre-arching of the web plate of box girders of welded plate structures, the method of reducing welding deformation

Bridge crane main girder deflection detection and correction methods I. Bridge (gantry) crane main girder deflection detection in the bridge (gantry) crane safety inspection, the main girder arch detection is a very important content. jb1036-82 (general bridge...

The present invention relates to ships, and in particular relates to a method of modifying the structure of a ship. BACKGROUND TECHNOLOGY: 1. The hull structure needs to be modified during the construction of a ship, and it is common to divide a modification area in the hull and remove the original structure in the modification area

Manufacturing is the foundation of national strength, please pay attention to “metal processing” (mw1950pub).

影响焊接变形的因素有很多，总结起来主要有材料、结构和工艺3个方面。 在保证结构承载力的情况下，尽可能采用较小的焊缝尺寸，减少焊接热输入对材料性能的影响。
