本文结合钛复层复合钢板的特性,介绍了山东鲁西化工集团蓝瑞分公司烧碱装置钛钢复合板设备阳极液循环槽焊接工艺及焊接质量重要控制点,以及该设备钛钢复合板焊缝无损检测一次合格率达99%的事实。依此证明,其焊接工艺是切实可行的,其焊接质量重要控制点是准确的。证明加强钛贴条的密封程度、母材与焊材的清洁度以及焊接熔池的气体保护等是保证钛焊接质量的重要条件,实践证明其焊接工艺是有效且可行的。
Based on the characteristics of titanium clad composite steel plate, this paper introduces the anodic liquid circulation tank welding process and important control points of welding quality of the titanium steel composite plate equipment of Shandong Ruixi Chemical Group Blue Rui Branch caustic soda plant, as well as the equipment of titanium steel clad plate weld Nondestructive testing a pass rate of 99% of the facts. It proves that the welding process is feasible and the important control point of welding quality is accurate. It is proved that strengthening the sealing of titanium strip, the cleanliness of base metal and welding consumables and the gas protection of welding pool are the important conditions to ensure the quality of titanium welding. The welding process is proved to be effective and feasible.
