Carbide Studs are cylindrically shaped standard parts (fasteners) with threads on both ends. Widely used in electric power, chemical industry, oil refining, valves, railways, bridges, steel structures, auto parts, machinery, boiler steel structures, pendant towers, large-span steel structures and large buildings. It is a very versatile standard part.

What are the welding methods for Carbide Studs?
First, you need to clean up the rusted rust and dust impurities on the Carbide Studs. After that, you can apply some hard film anti-rust oil to prevent rust. You can also apply paint, epoxy resin, and some asphalt. These coatings can Play a good anti-rust effect. If it is for aesthetics, you can use some clear hardcoat anti-rust oil or the same paint as the other color parts.
We distinguish low carbon steel, medium carbon steel and high carbon steel and alloy steel by the content of carbon in carbon steel material.
1. Low carbon steel C%≤0.25%. Mainly used for 4.8 grade bolts.
2. Medium carbon steel 0.25%< grade bolts and 8.8 etc. Mainly used for No. 8.8 steel, basically called 1035 abroad, CH38F, 1039, 40ACR
No. 45 is usually referred to as 35> in China
3. High carbon steel C%>0.45%. The current market. Basically not used.
4. Alloy steel: Add alloying elements to ordinary carbon steel to increase some special properties of steel: such as 35, 40 chromium molybdenum, SCM435. Alloy steel is mainly used in the production of high performance grade Carbide Studs.
(2) Stainless steel
Performance Class: 45, 50, 60, 70, 80
Divided into 201, 304, 316, 316 and so on. Simply put, the higher the grade, the better the corrosion resistance and the stronger the high temperature resistance. The reason is that the content of Ni is different. The higher the Ni content, the more corrosion-resistant, and the stronger the corrosion-resistant ability at high temperature. Among the strengths of 316 and 3161, the strength of 316 is better, and the yield strength and tensile strength are greater. However, the high temperature and corrosion resistance of 316I is stronger than that of 316.
1. Unstable arc stud welding. The capacitor discharges between the workpiece and the end of the Carbide Studs, completing the stud weld. Since capacitive discharge is an unstable arc process, that is, the arc voltage, as well as the welding power source, changes rapidly and the process is uncontrollable. This unstable arc stud welding is commonly referred to as capacitor energy storage stud welding, or capacitor discharge stud welding.
2. Arc stud welding, also known as short cycle stud welding. The welding arc undergoes current waveform modulation, covering a larger welding arc current, as well as a smaller pilot arc current. The power supply for this short-term stud welding is usually two parallel power supplies, which successively supply power to the pilot arc and the welding arc.
The widespread use of Carbide Studs has continuously increased the demand for them in the market. Zhuzhou Jinxin Group Cemented Carbide Co., Ltd., as a Chinese pioneer in Carbide Studs can ensure the machines’ quality and after-sales service.
