Webb4 dec. 2024 · Keyhole welding requires metals with poor thermal conductivity. If the parent material has poor thermal conductivity, this results in heat accumulation in a concentrated area, which is a prerequisite for the keyhole method. Typical materials used are high-alloy or Duplex steels. In contrast to this, the better the thermal conductivity, the less ... WebbCold welding is a unique bonding technique that can create very strong bonds without the use of heat. It has been used since the Bronze Age, yet only really began to be understood scientifically in the 16th Century.
