摘要
针对公司内泵系列产品铸铁件多、铸铁件铸造缺陷补焊性能差、报废成本高的问题,提出了使用结构钢焊条铸铁补焊工艺,解决了铸铁补焊难、易产生裂纹等焊接难题,大大降低了生产成本,促进了生产率的提高。
For the pumps more than pieces of cast iron products, iron casting defect repair welding pieces of poor performance, high cost of end - of- life issues raised by the use of structural steel welding rod iron repair welding technology to solve a difficult repair welding of cast iron, welding and so easy to have a crack problem, greatly reduced the cost of production, and promoted an increase in productivity.
