Embodiment
[0020] The chemical compositions of the austenitic stainless steel welding wires with antibacterial properties of Examples 1-6 are shown in Table 1. Controlled smelting is carried out according to the chemical composition range of the welding wire of the present invention. The smelted steel ingots are rolled into wire rods, and then heat treated, drawn, and finally obtained. diameter of the wire. Manual arc welding was carried out on the test plate with welding wires of three components. The test plate was a 20mm thick 316L stainless steel plate, the welding voltage was 13V, the welding current was 180A, the welding speed was 100mm / min, the shielding gas was high-purity argon, and the interlayer temperature was less than 100°C.
