What welding method should be used for welding iron, aluminum, copper and stainless steel
How to weld mild steel? Low carbon steel has low carbon content and good plasticity, and can be prepared into various forms of joints and components. In the welding process, it is not easy to produce hardened structure, and the tendency to produce cracks is also small. At the same time, it is n...Read more -
How to distinguish molten iron and coating during manual arc welding
If it is manual arc welding, first of all, pay attention to distinguish molten iron and coating. Observe the molten pool: the shiny liquid is molten iron, and what floats on it and flows is the coating. When welding, pay attention to not let the coating exceed the molten iron, otherwise it is eas...Read more -
The origin of CNC tools, unimaginable greatness of human beings
The development of knives occupies an important position in the history of human progress. As early as the 28th to 20th centuries BC, brass cones and copper cones, drills, knives and other copper knives had appeared in China. In the late Warring States period (third century BC), copper knives wer...Read more -

CNC common calculation formula
1. Calculation of trigonometric functions 1.tgθ=b/a ctgθ=a/b 2. Sinθ=b/c Cos=a/c 2. Calculation of cutting speed Vc=(π*D*S)/1000 Vc: line speed (m/min) π: pi (3.14159) D: tool diameter (mm) S: speed (rpm) 3. Calculation of feed amount (F value) F=S*Z*Fz F: Feed amount (mm/min) S: speed (rpm...Read more -
We use welding rods every day, do you know the effect of the coating
The coating plays a role in complex metallurgical reactions and physical and chemical changes during the welding process, basically overcoming the problems of light electrodes during welding, so the coating is also one of the main factors that determine the quality of the weld metal. Electrode co...Read more -
How much do you know about argon protection
Argon arc welding is based on the principle of ordinary arc welding, using argon to protect the metal welding material, and through high current to make the welding material melt into a liquid state on the base material to be welded to form a molten pool, so that the welded metal and the welding ...Read more -
Harmful factors of welding materials, what should be paid attention to when using welding materials
Harmful factors of welding materials (1) The main research object of welding labor hygiene is fusion welding, and among them, the labor hygiene problems of open arc welding are the biggest, and the problems of submerged arc welding and electroslag welding are the least. (2) The main harmful fac...Read more -
Generation and Elimination of DC Component in AC TIG Welding
In production practice, alternating current is generally used when welding aluminum, magnesium and their alloys, so that in the process of alternating current welding, when the workpiece is the cathode, it can remove the oxide film, which can remove the oxide film formed on the surface of the mol...Read more -
Why does the machine tool collide Here’s the problem!
The incident of a machine tool colliding with a knife is big and big, let’s say small, it’s really not small. Once a machine tool collides with a tool, hundreds of thousands of tools may become waste products in an instant. Don’t say I’m exaggerating, it’s true. A machine too...Read more -
