There are many types of welding rods on the market, such as 47018 welding rods and so on, so what is 47018 welding rod material? Next, I will briefly give you an introduction.
A, 47018 welding rod is what material
47018 is about the standard provisions of the welding materials of pressurized equipment, 47018 welding rod refers to the pressurized equipment with welding rod, mainly stainless steel welding rod, carbon steel welding rod, low alloy welding rod and other different materials. One of the stainless steel welding rod belongs to the acidic welding rod, its diameter is usually 2.5-5.0 millimeters, is widely used in chemical, petroleum, medical machinery and other fields. We are in the choice of welding rod material, according to the material of the base material, welding process performance and other aspects to determine the type of welding rod.
Two, the use of welding rods to pay attention to what
1, we use welding rods to first determine whether the electrode is appropriate, such as the tensile strength of the electrode to be similar to the base material, according to the working conditions of the weld to choose the right electrode. For example, we want to weld carbon steel and stainless steel together, then we can use stainless steel welding rod. If you use carbon steel welding rod will cause some corrosion of the base material, affecting the mechanical strength of the metal and so on.
2, if the electrodes are not well preserved moisture, then we need to use the electrodes before welding, the electrodes need to be dried first. For example, alkaline structural steel welding rod, its drying temperature is usually set at 300-400 degrees, drying time is generally 1 -2 hours. If it is acidic stainless steel welding rod, its drying temperature is usually 150 degrees, drying time for 0.5-1 hours and so on. After the product is dried, we also need to do performance tests to check whether the product can continue to use.
3, in welding electrodes, must be strictly in accordance with the requirements of the construction process. For example, when welding, we must first clean up the dirt at the joints of the base material. Welding rods with a torch, the torch can be tilted a little bit, not and the base material is vertical, otherwise we are not good to observe the welding of welding rods and so on.
Summary: On the 47018 welding rod is what material, I will briefly introduce to you here. I hope that after reading this article, you can have an understanding of 47018 welding rod.
