Computer software systems in the field of welding are mainly used in the following areas: 1.1. Computer simulation techniques including simulation of the welding thermal process, welding metallurgical processes, welding stress and deformation. Welding is a complex process involving the disciplines o

1) Laser power. There is a laser energy density threshold in laser welding, below which the depth of melt is shallow, and once this value is reached or exceeded, the depth of melt increases substantially. Only when the laser power density on the workpiece exceeds the threshold (material dependent),

For manual arc welding "single-sided welding double-sided forming" process according to the method of operation, can be divided into continuous welding method and intermittent arc extinguishing welding method.In low carbon steel and low alloy steel welding the first layer almost always use intermitt

Cold cracking is a more common type of cracking in welding production, which occurs when the weld is cooled to a lower temperature, for low-alloy high-strength steels, around the martensitic transformation temperature. The three elements of cold crack formation are the hardening tendency of the stee

This type of steel as a high-strength welded structural steel, the carbon content is limited to low, usually less than 0.18% carbon mass fraction, and in the design of the alloy composition are also considered weldability requirements, so low carbon tempered steel welding is basically similar to nor

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.
