The reason why the gas shielded welding machine needs to change the wire feeding tube when welding aluminum can be analyzed from the following points:The aluminum welding wire is softer than the iron or stainless steel welding wire, so the friction in the iron conduit will be larger, which will affect the wire running and lead to the phenomenon of unsmooth wire running.Solution: Change the special conduit for aluminum, such as graphite conduit, to reduce the resistance of welding wire in the con

What is brazing? How is brazing classified? What are the characteristics of brazed joints?Brazing is to use metal with lower melting point than the base metal as brazing filler metal. After heating, the brazing filler metal melts and the weldment does not melt. The liquid brazing filler metal wets the base metal, fills the joint gap and diffuses with the base metal, thus firmly connecting the weldments together.According to the different melting points of solders, brazing can be divided into sof

From the point of view of welding process, we should also pay attention to the following matters:First, clean the surface of aluminum alloy before welding, and all dust and oil pollution must be removed. You can use to clean the surface of aluminum alloy welds. For thick aluminum alloy, clean it with wire brush first, and then clean it again.Second, the welding wire material used should be as close as possible to the parent metal, and whether to choose aluminum-silicon welding wire or aluminum-m

It can be said that Teflon is a very stable polymer material, which can't chemically react with 99% of chemicals, so it can be described as the little prince of high temperature in chemistry. Teflon is hardly corroded by any chemical agent except molten alkali metal. For example, when boiled in concentrated sulfuric acid, nitric acid, hydrochloric acid or even aqua regia, its weight and performance have no change. It is almost insoluble in solvents and only slightly soluble in all alkanes (a

Controlling alloy: The process of making aluminum welding wire is a complicated process, but INDALCO has obvious and unique advantages in this respect. First, we use automatic tilting furnace to efficiently produce all aluminum welding wires. With this kind of mechanical equipment, we can strictly control the regular tolerance of chemical composition in alloy. The alloy has been carefully refined to ensure that the content of basic metals and impurities in hydrogen is very small.Drawing: We adop
