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 cleaning oil, and provides synthetic lubricating cleaning oil for an aluminum alloy MIG welding wire. The synthetic lubricating cleaning oilis composed of, in percentage by weight, an extreme pressure anti-wear additive, a demulsifying agent, an antirust agent, an antioxidant and base oil, wherein the extreme pressure anti-wear additiveis obtained by compounding thiophosphoric amide ester, 1-hydroxyethylidene-1(HEDP) and isooctyloxy cerous borate; and the synthetic lubricating cleaning oil is obtained by compounding and optimizing the base oil and is used before the last procedure of producing the aluminum alloy welding wire, namely, winding a finished product, the synthetic lubricating cleaning oil is uniformly smeared on the surface of the aluminum alloy welding wire according to a certain amount through oiling equipment, the cleaning and lubricating effects on the surface of the aluminum alloy welding wire are achieved, through multiple aluminum alloy welding tests, the resistance of the welding wire in the conveying process is uniform, black 'silicon islands' cannot be generated on the surface of a welding seam, andfew air holes are seen after the surface of the welding seam is polished.

Description

Technical field [0001] The present invention belongs to the technical field of lubrication cleaning oil, and specifically, a synthetic lubricating oil of aluminum alloy MIG welding wire. Background technique [0002] Aluminum welding wire is a soft material relatively poor in columnar intensity, and is sensitive to the solubility of hydrogen, so it depends to a large extent on its method and control in the production process. The means is reasonable or not, and the surface cleaning of the welding wire and the surface lubricity of the welding wire in the factors in the performance of MIG aluminum welding wire. Aluminum alloy wires inevitably use lubricants when the mold is drawn, and they are mostly mixed oily substances such as oil, cylinder oil, showing a large number of splashes and pores, weld, and surrounding mothers during unmancing wire welding process. There is a black gray surface on the surface, and the weld is formed. The main reason is that the surface oil is carbonize...
