一种焊接H型钢构件加工工艺

本发明公开了一种焊接H钢构件加工工艺，包括采用数控火焰/等离子切割机，对翼缘板和腹板进行下料；对所有下料后的板材采用辊式矫平机进行矫平，然后对翼缘板与腹板的待焊区域及其两侧进行抛丸除锈，并在除锈后喷涂车间底漆；采用数控H型钢组立机进行组立；根据焊接工艺评定确定的变形规律，在焊接夹具上预设反变形量；采用双弧双丝埋弧焊设备，在构件两侧同步对称施焊翼缘板与腹板之间的主角焊缝；焊接过程中，通过红外热像仪实时监测焊缝及附近区域的热循环，并通过焊接电源的数据采集模块实时记录电流、电压数据焊接完成后，将构件连同胎架移至保温区；对焊接并消应力后的构件进行检测，若仍有局部超标变形，采用数控液压矫直机进行精矫。
