What welders must know Macroscopic analysis of weld defects
The quality requirements for welded structures, welded products, and welded joints are multi-faceted. They include internal requirements such as joint performance and organization. At the same time, there must be no defects in appearance, shape, size accuracy, weld seam formation, surface and int...Read more -
What points should we pay attention to when welding high carbon steel
High carbon steel refers to carbon steel with w(C) higher than 0.6%. It has a greater tendency to harden than medium carbon steel and form high carbon martensite, which is more sensitive to the formation of cold cracks. At the same time, the martensite structure formed in the welding heat-affecte...Read more -
Welders, how do you understand steady, accurate and ruthless

Now the editor has summarized his own methods for everyone to learn and communicate. Please feel free to correct me if I am wrong. It can be summed up in thr...Read more -
When it comes to drilling cycle selection, we usually have three choices:
1.G73 (chip breaking cycle) is usually used to process holes whose depth exceeds 3 times the diameter of the drill bit, but does not exceed the effective edge length of the drill bit. 2.G81 (shallow hole cycle) is usually used to drill center holes, chamfering and does not exceed the drill bit...Read more -
CNC operation panel explanation, see what these buttons mean
The operation panel of the machining center is something that every CNC worker comes into contact with. Let’s take a look at what these buttons mean. The red button is the emergency stop button. When this switch is pressed, the machine tool will stop, usually in emergency or unexpected condition...Read more -
Basic knowledge to help you get started with UG programming
CNC machining programming is to write the process of machining parts, process parameters, workpiece size, direction of tool displacement and other auxiliary actions (such as tool changing, cooling, loading and unloading of workpieces, etc.) in the order of movement and in accordance with the prog...Read more -
What is the reason for poor weld formation
In addition to process factors, other welding process factors, such as groove size and gap size, inclination angle of the electrode and workpiece, and spatial position of the joint, can also affect the weld formation and weld size. Xinfa welding equipment has the charact...Read more -
