We all know that the production process stainless steel filter is mainly used in welding process, in order to ensure the production of quality stainless steel filter, the spot welding process must pay attention to the impact of the welding current welding quality. Next, we come to understand the knowledge of this area. 1, the changes affect the welding current on weld quality. 2, when the current is too small, we all know that stainless steel filter is made of spot welding. Welding inadequate heating, can not always reach the melting temperature. 3, increasing the current melts the middle, but the scale is too small, yet penetration. 4, when the current is too large, the current density of the forward heat increased, if the intermediate diameter to expand much faster expansion rate over the plastic ring, it appeared splash. 5, followed by a splash of constitution, it can constitute indentation depth, large-scale shrinkage and other shortcomings, reducing the joint strength. Using high-quality high-carbon, various wire as raw material preparation; after rolling the first series, two-way separated wave bending, flat curved, two-way bending, one-way wave bending, solid structure. Ginning network there is no uniform standard form, because the material, wire diameter, with different pore sizes and evolved a lot. http://www.apkefeng.com/kfnews/91.html crimped wire mesh from the shape can be divided into two categories, one is called the entire weaving crimped wire mesh, a class called Order flowers ginning network. Both the shape of the ginning network what the similarities and not the same? Several important aspects from raw materials, such as usefulness and weaving process, the entire weaving crimped wire mesh and crimped wire mesh can order flowers are substitutes. Both are not essentially different. If I have to pick out one or two years, first and foremost is to use terms. Entire weaving crimped wire mesh made out of soft mesh match some, but wear flowers than the order to go through with some ginning network. On the basis of this difference, the whole order flowers woven crimped wire mesh and cotton net basis would need to use different occasions. Entire weaving crimped wire mesh refers to a single mesh-type center no waves and turns, order flowers ginning network refers to a single mesh has had three or more waves tortuous type integer woven wire crimped wire mesh used for small macroporous crimped wire mesh, crimped wire mesh order to spend more for the large holes crimped wire mesh. Centre status can also be used with the entire order flowers woven
