The basic knowledge of thread gauge, you can earn it when you see it
Basic knowledge of thread gauges A thread gauge is a gauge used to test whether a thread complies with regulations. Thread plug gauges are used to test internal threads, and thread ring gauges are used to test external threads. Thread is an important and commonly used structural element. Threads ...Read more -
A complete collection of steel knowledge, good things are to be shared! !
1. Mechanical properties of steel 1. Yield point (σs) When the steel or sample is stretched, when the stress exceeds the elastic limit, even if the stress does not increase, the steel or sample still continues to undergo obvious plastic deformation. This phenomenon is called yielding, and the min...Read more -
Zero-based hands-on argon arc welding
（1） Start up 1. Turn on the power switch on the front panel and set the power switch to the “ON” position. The power light is on. The fan inside the machine starts to spin. 2. The selection switch is divided into argon arc welding and manual welding. （2） argon arc welding adjust...Read more -
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
