How to choose the welding rod model when welding different types of steel?
I believe that all welders know that welding rods are necessary for welders to weld. After the welding tongs are connected to the welding rod, they can start working on the workpiece. However, do welders know the model of your welding rod? The use of welding rods is very particular. Weldin...Read more -
The most comprehensive protection strategy in history: How to protect your eyes when welding?
The welding industry is not only hard work, but also dangerous. It is very necessary for welders to pay attention to eye health. Do you know how welders protect their eyes? In this issue, the editor will introduce to you how welders protect their eyes and what we should do after being burned? Xi...Read more -
What is “arc welding” and how to move the wire?
What is arc pick welding? When the first molten pool is formed, the electrode is picked up, but the arc is not extinguished. After the molten pool solidifies, the electrode is guided to the top of the first molten pool to spot weld the second molten pool. Then the electrode is picked up again, an...Read more -
This article will help you understand the welding performance of metal materials
Welding performance Metal weldability refers to the adaptability of metal materials to welding processing. It mainly refers to the difficulty of obtaining high-quality welded joints under certain welding process conditions (including welding materials, welding methods, welding proc...Read more -
What is the reason for the sticky electrode during welding
Electrode sticking is the phenomenon of electrode and part sticking together when the welder spot welds and the electrode and parts form an abnormal weld. In severe cases, the electrode is pulled out and the cooling water flow causes the parts to rust. There are four main reasons for electrode st...Read more -
When welding aluminum tubes, the surface always turns black. What should I do
Porosity is very common in aluminum welding. There are a certain amount of pores in the base material and in the welding wire, so it is necessary to avoid large pores during welding to ensure that the pores do not exceed the standard. When the humidity exceeds 80℅, welding must be stopped. The pr...Read more -
Narrow gap welding process should not use a single concave weld, so what should be used
The narrow gap welding process belongs to the deep and narrow groove welding process of thick workpieces. Generally, the depth-to-width ratio of the groove can reach 10-15. When the submerged arc welding process is used, there is a problem of slag removal and removal of the slag shell of each we...Read more -
Welding of titanium
1. Metallic properties and welding parameters of titanium Titanium has a small specific gravity (specific gravity is 4.5), high strength, good resistance to high and low temperatures, and excellent crack resistance and corrosion resistance in wet chlorine. The mechanical...Read more -
Take you closer to plasma arc welding
Introduction Plasma arc welding refers to a fusion welding method that uses a high-energy-density plasma arc beam as a welding heat source. Plasma arc welding has the characteristics of concentrated energy, high productivity, fast welding speed...Read more -
Do you know the rolling welding process
1. Overview Roll welding is a type of resistance welding. It is a welding method in which the workpieces are assembled to form a lap joint or butt joint, and then placed between two roller electrodes. The roller electrodes press the weldment an...Read more -
Welding tips Precautions for galvanized pipe welding
Galvanized steel is generally a layer of zinc coated on the outside of low-carbon steel, and the zinc coating is generally 20μm thick. The melting point of zinc is 419°C and the boiling point is about 908°C. The weld must be polished before welding The galvanized layer a...Read more -
Tips How to distinguish welding slag and molten iron during welding
During the welding process, welders can see a layer of covering material floating on the surface of the molten pool, which is commonly known as welding slag. How to distinguish welding slag from molten iron is very important for beginners. I think it should be distinguis...Read more
