冷却至原始温度后，整个接头区焊缝及近缝区的拉应力区与母材在压应力区数值达到平衡，这就产生了结构本身的焊接残余应力。 2）焊接热输入的影响：一般情况下，热输入大时

Corner welds are a common feature in steel structure welding; their diversity not only presents challenges for welders but also imposes different standards upon them. So, how can one successfully complete corner welds to meet all the relevant requirements? We will explain this in detail below.

Methods for preventing and minimising welding distortion must take into account the design of the welding process and how to counteract thermal cycling during welding. Contraction cannot be eliminated, but it can be controlled.

[Abstract] The detection and correction of deformation in the main girder of bridge (gantry) cranes is a common issue faced by enterprises in their production processes. This paper outlines several methods for detecting and correcting such deformation, describes their characteristics, and explains their scope of application. Keywords: main girder deformation, detection, correction

316L stainless steel welded tubes are widely used in many industrial applications; their unique chemical composition and properties enable them to perform exceptionally well under specific conditions. 316L stainless steel welded tubes are renowned for their outstanding corrosion resistance, high-temperature tolerance, and excellent machinability and weldability.
