在我厂机车车辆焊接结构中,焊后变形通常是用火工锤击来矫正的。例如:机车锅炉内外火箱焊接后,在焊缝上经常出现凸凹不平现象,这就要靠火工加热后,以猛烈的锤击来矫平的(不用水冷)。这种矫正方法对钢板及焊接接头质量的影响如何?就是本试验的目的,试 In our factory locomotive and rolling stock welding structure, after welding deformation is usually used to deal with fire hammer to correct. For example: locomotive boiler fire inside and outside the box after welding, weld often appear rugged, which rely on the fire heating, with a heavy hammer to leveling (without water). This correction method on the quality of steel and welded joints how? Is the purpose of this experiment, the test
