The circuit board is an essential accessory in all electronic equipment or electronic products. All components need to be attached to the board and electrically connected through the pads on the PCB board in order to operate. The solder pad is the most important basic unit in PCB circuit board desig

As the most harmful type of welding defects, welding cracks seriously affect the performance and safety reliability of welded structures.-----

With the development of industry, there are many different types of metal materials that have emerged. The common ones are plated steel sheets, stainless steel sheets, aluminum alloys, copper alloys and other materials. When spot welding machine is used to weld these corresponding metal materials, d

The submerged arc welding process is ideal for important applications in pipeline, pressure vessel and tank, rail fabrication and major construction, with the simplest single wire forms, double wire construction, tandem double wire construction and multi wire construction.

Welding cracks are the most harmful type of welding defects, which seriously affect the performance and safety and reliability of welded structures. Today, I will take you to know one of the types of cracks - layered cracks.

Due to the increasingly prominent pressures such as environmental protection, energy conservation and emission reduction, carbon peaking, and carbon neutrality, lightweight will be an inevitable trend in automobile manufacturing. The concept of lightweight originated in motorsports, its advantage is
