快速判断堆焊耐磨板关注的几个点!

所属分类:常见问题 发布时间:2021-05-14 来源:https://www.lcnaimoban.com/ 浏览量:

由于堆焊耐磨板具有不错的使用性能,使用范围较广。但也看到,有的企业采购人员不清楚如何区分堆焊耐磨板质量的好坏。
Because of the good performance of hardfacing wear-resistant plate, it has a wide range of applications. But also see, some enterprise purchasing personnel do not know how to distinguish the quality of hardfacing wear-resistant plate.
一.尺寸
1、 Dimensions
第一看整板尺寸是否复合规格,一般产品板面上会清楚准确地标注出整板编号、整板尺寸和焊接规格。第二看焊道尺寸是否均匀,焊道宽窄不均,误差超过5mm一般为不合格产品,焊枪最后一道焊道除外。另外焊接规格、必须符合要求,否则为不合格产品。?
First, whether the whole plate size is composite specification, the overall plate number, the whole plate size and welding specification will be clearly and accurately marked on the surface of the general product. Second, it is necessary to see whether the size of the weld bead is uniform, the width and width of the weld bead are uneven, and the error is generally unqualified products, except for the last pass of the welding gun. In addition, welding specifications and requirements must be met, otherwise, they are unqualified products.?

二.厚度与平整度
2、 Thickness and flatness
不同规格的堆焊耐磨板有不同的厚度标准,测量焊道的中间,测五个值取平均值。平均厚度公差0到0.7mm最为完美,厚度公差>1mm一般都是不合格产品。

Different thickness standards are available for different specifications of hardfacing wear plates. Measure the middle of the weld bead and take the average value by measuring five values. The average thickness tolerance is the most perfect from 0 to 0.7mm, and the thickness tolerance is generally unqualified products.
板 面 平 整
Flat plate surface
三.表面成型
3、 Surface forming
表面成型要注意的细节比较多,第一观察是否有坑(直径大于4mm,深度大于2mm的凹痕定义为坑),坑是否修复一般修复痕迹单个坑修复面积最好在20mm*20mm内。第二要看焊道表面要注意是否存在有气孔(耐磨层内由于气体溢出不好没有被敷熔金属填满的空穴。),焊道成型不好(电流低或焊丝原因造成的),断弧等问题。第三要观察基板与耐磨层的结合。耐磨板大面积脱落,耐磨层与基板结合处大面积气孔,焊接后造成基板出现裂纹、焊接时焊漏等问题一般为不合格产品。?
There are many details to be paid attention to in surface forming. First, observe whether there are pits (pits with diameter greater than 4mm and depth greater than 2mm are defined as pits), and whether the repair area of single pit with general repair traces is better within 20mm * 20MM. Second, it is necessary to pay attention to whether there is air hole on the surface of weld bead (the hole in the wear-resistant layer is not filled by the deposited metal due to the bad gas overflow), The welding bead is not formed well (caused by low current or wire reason), arc breaking and other problems. Third, the combination of substrate and wear-resistant layer should be observed. The wear-resistant plate falls off in large area, and the joint of the wear-resistant layer and the substrate have large area of air holes. The cracks in the base plate and welding leakage are generally unqualified products.?
