Problems solved by technology

And at present, including clean lubricating oil, most of them are composed of base oil, additives and nanoparticles, which all need to contain a large amount of nanoparticles. Nanoparticles are not only complex in composition, but also expensive
Moreover, the protective film formed by the granular lubricating oil may be detrimental to the subsequent welding of the aluminum alloy welding wire, because under conditions such as welding high temperature, these substances are formed on the surface of the welding wire in many cases, which will lead to unstable combustion and poor weld formation.
Although it may solve the problem of welding wire feedability, it does not focus on the cleaning of the welding wire surface, let alone the impact on the weld porosity during welding
[0004] And for aluminum alloy MIG welding wire, these metal particles will also be added to the welding wire during welding. Silicon, manganese, iron and other trace elements are formed by the interaction with oxygen, but it is very easy to form oxides, which appear in the weld Black "silicon islands" are difficult to clean, affect the appearance of the weld, and even cause pores in the weld, thereby affecting the performance of the weld

Abstract

The invention belongs to the technical field of lubricating and cleaning oils, and provides a synthetic lubricating and cleaning oil for an aluminum alloy MIG welding wire. Oxygen agent and base oil, wherein the extreme pressure anti-wear additive is obtained by compounding thiophosphoramidate, 1-hydroxyethylidene-1,1-diphosphonic acid (dioctyl) ester and isooctyloxy cerium borate, through The compounding of base oil is optimized to obtain synthetic lubricating and cleaning oil, which is used before winding the finished product in the final process of producing aluminum alloy welding wire. After several aluminum alloy welding tests, the resistance of the welding wire during the conveying process is uniform, the black "silicon island" will not be formed on the surface of the weld, and there are fewer pores after the surface of the weld is polished.

Description

technical field [0001] The invention belongs to the technical field of lubricating and cleaning oils, in particular to a synthetic lubricating and cleaning oil for aluminum alloy MIG welding wires. Background technique [0002] Aluminum welding wire is a soft material with relatively poor columnar strength and is extremely sensitive to the solubility of hydrogen in melting, so its success in a production environment depends largely on its method and control in the production process. Whether the method is reasonable or not, the factors that have the greatest influence on the performance of MIG aluminum welding wire are the surface cleanliness of the welding wire and the surface lubricity of the welding wire. The aluminum alloy welding wire inevitably uses lubricants when drawing the die. Most of them are mixed oily substances such as engine oil and cylinder oil. The welding test shows that a large number of spatters and pores are generated during the welding process of the u...
