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 -

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 -
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 -
Note that not all post weld heat treatments are beneficial
Welding residual stress is caused by the uneven temperature distribution of welds caused by welding, thermal expansion and contraction of weld metal, etc., so residual stress will inevitably be generated during welding construction. The most common method to eliminate re...Read more -
Why does the machine tool collide with the tool
The matter of a machine tool collision is not a small matter, but it is also a big one. Once a machine tool collision occurs, a tool worth hundreds of thousands of yuan may become waste in an instant. Don't say I am exaggerating, this is a real thing. ...Read more -
The precision requirements of each process of CNC machining center are worth collecting
Precision is used to indicate the fineness of the workpiece product. It is a special term for evaluating the geometric parameters of the machining surface and an important indicator for measuring the performance of CNC machining centers. Generally speaking, machining acc...Read more
