The wholesale market for aluminum welding electrodes is booming. Aluminum pipe welding wire is one of the products that has many applications in the welding industry and today it is produced in various sizes and shapes and will have many uses, due to the frequent use of welding wire. Demand for their purchase is high day by day. Therefore, aluminum pipe welding wire is sold in different ways so that customers can easily buy these products in the volume they need.
Review of Aluminum Electrode and Its Application in Welding
In an important industry called, welding electrode uses different wires are used, each of which, according to their different materials, are in different categories. In fact, each of these types of products are produced for different purposes, and these items are divided into different categories based on price. In order to be able to use these products properly, you need to know the different types and buy the product carefully enough. If we want to tell you about the types of lower amperage aluminium electrode wires, it must be said that some of these products are made of aluminum and are made of this widely used material.
In welding with aluminum, we face the problem of folding and cracking of the weld surface, because the expansion and contraction of aluminum due to welding and cooling is more than steel. Fixers and retainers are commonly used to reduce the effects of this problem. Welding aluminum requires a lot of skill and experience, because if it is exposed to too much heat, it does not show discoloration; Therefore, melting and adsorption of gas can occur. The melting point of the metal welding electrode is 450 to 660 ° C, while the pure melting point of pure iron is 1535 ° C.
The heat of boiling causes the surrounding areas to soften. These areas, which are made of aluminum alloys and are hard, now soften, which is likely to crack in the weld area. For the above reasons, welding with aluminum is a difficult task and the electrode should be selected according to the classification according to the characteristics of the surface to be welded in order to deliver quality welding.
Tensile Strength Importance In Choosing Welding Electrodes?
In welding joints with high strength and thickness, the mechanical properties of the weld, including tensile strength, yield strength, percentage of relative elongation and toughness, are of great importance. Some of the factors affecting these properties are the type of electrode used and preheated. Cellulose electrodes Unlike alkaline type, they have more hydrogen and this has a negative effect on mechanical properties such as toughness
So it has been tried to replace this decrease in mechanical properties to some extent by replacing 8108 E alkaline electrode with 8101 E cellulose electrode. It has been shown that the amount of preheat heat and heat between passes is useful in reducing the formation of hydrogen cracks. The choice of preheating and interpass temperature depends on the type and amount of alloying elements as well as the thickness of the part. Therefore, in welding high grade pipes (API 5L X70) which have more equivalent carbon as well as high thickness,
it is necessary to observe preheating and maintain the temperature between passes. Cracks due to non-compliance with the preheating temperature and between passes may not occur even after welding, but this problem appears in the bending test (PQR) or in cases where the pipe is subjected to dynamic stresses. Therefore, the correct choice of electrode and also determining the appropriate preheating and interpass temperature to achieve the desired mechanical properties, will be effective.
4 Amazing Features of Good Aluminum Welding Electrodes
Aluminum is a very popular metal in the world industry as well as in our country. The charms that can be seen in this metal, has made it the most consumed industrial metal after iron. Surely you also want to know what properties and characteristics distinguish aluminum among other metals and elements of the periodic table?
1) Lightweight yet high strength: The density of aluminum is only 7.2 grams per cubic centimeter. That is about 1⁄3 the weight of steel! But at the same time, aluminum alloys are usually strong and, in fact, have a high strength-to-weight ratio. Taking advantage of this feature makes aluminum widely used today in the automotive, aircraft and other transportation industries. The use of this metal reduces weight, reduces fuel consumption and, consequently, increases the efficiency of these devices.
2) Excellent corrosion resistance: Corrosion resistance of most aluminum alloys is lower than that of pure aluminum, but some of these alloys, such as marine alloy 5083, have very high corrosion resistance and are used in humid and corrosive environments. These alloys also have a higher resistance during the anodizing and painting process. Anodizing operation increases the thickness of the oxide layer and improves the corrosion resistance of aluminum.
3) Proper electrical and thermal conductivity: Although the electrical conductivity of aluminum is lower than that of copper, it can be an excellent choice for power transmission lines due to its lower density than copper. For this reason, this metal is used in the manufacture of cables and transmission lines in the electricity industry.
4) Reflection of light and heat: One of the features of aluminum is that it has a good ability to reflect light and heat. In fact, this metal can reflect up to 95% of the incoming heat! Therefore, the use of this metal in the construction of buildings can cool their interior space. Used in the construction of solar panels, suspended ceilings and gables, facades of buildings and some other applications of this metal.
