Calculation of layered welding material dosage based on model of variant parameter groove

焊材消耗用量计算是焊接工艺设计的重要内容.在双边双面U形坡口参数描述的基础上,改变参数演变为其它常见类型坡口,实现常见坡口类型统一化参数模型,便于焊缝截面面积计算.通过对该模型焊缝横截面分解,将复杂截面面积求解简化为简单图形面积计算,计算各焊接工序焊材消耗用量必须求解对应焊层横截面面积,提出了焊层截面面积计算思想并给出基于焊层厚度横截面面积计算理论,在此基础上设计了分层的迭代计算算法并开发了软件计算工具,说明了软件使用方法,测试计算了一个实际坡口焊材用量.结果表明,能够显著提高焊材计算精度和效率.

Computing dissipative welding material dosage is an important content of welding procedure.The parameter model of normal groove type is unified by modifying parameters on basic of describing both-side double-U-groove parameters,which is easy to compute cross-section area of weld.By decomposing the crosssection of weld on the model,calculating complex area is predigested to computing area of some simple graphs.For getting dosage of welding material from each welding procedure,the cross-section area of corresponding welding layer should be obtained.An idea and theory of calculating welding layer cross-section on welding layer thickness are presented.The arithmetic of layered iterative calculation is designed and is realized in the software,which the usage of calculating tool is explained.By calculating material from a real groove,the result shows that precision and efficiency of computing dissipative welding material are enhanced obviously.
