The experts will lead you to understand the cause of poor joint after spot welding of hardened steel and high carbon steel
The defects of quenched steel and high carbon steel welding mainly include joint embrittlement and joint crack. The solution is to adopt soft standard welding and increase the tempering current.If multi-pulse welding is used, it is necessary to pay attention to the interval time between pulses to ensure that the solder joint is cooled below the temperature of the martensite transition point, and the tempering current should not be too large to avoid the secondary quenching caused by the metal in the welding area re-exceeding the austenite transformation point.
