Description

technical field

[0001] The invention relates to the field of welding technology, in particular to a precision welding method for ultrafine stainless steel mesh. Background technique

[0002] Ultra-fine stainless steel mesh is usually woven from ultra-fine stainless steel wires. The ultra-fine stainless steel screen has the characteristics of wear resistance, heat resistance, acid resistance and corrosion resistance, and can screen various fine particle raw materials. Due to these properties, it is widely used in many fields such as mining, chemical industry, food industry and pharmaceutical industry. In many occasions, stainless steel wire mesh needs to be welded before use. If the wire diameter of the screen is smaller and the mesh number is larger, the welding difficulty will be higher.

[0003] In the production and production of ultra-fine stainless steel screens, according to the specific requirements of use, it is often necessary to weld them in order to connect two...
