High-carbon steel refers to w (C) higher than 0.6% of carbon steel, which has a greater tendency to harden than medium carbon steel, and the formation of high-carbon martensite, more sensitive to the formation of cold cracks.At the same time, the martensite organization formed in the welded heat-aff
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
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
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
