Welding of Q345R Steel Plates

When yield ratio is ≤ 0.75, more than 0.8 might have higher risk of crack forming. Preheating of steel plate welding is not required. When steel plate thickness is ≤34, preheat to 100 ~ 150 ℃ when steel plate thickness is > 34, additionally eliminate stress is needed after welding heat treatment, heating temperature range 600 ~ 640 ℃, usually air cooling after the heat preservation furnace cooling to under 400 ℃.
When the carbon content of partial minimum Q345R steel welding basic no strict limits on line, for it is overheating sensitivity is not high, cold cracking tendency is low, but for the goodness of plasticity and toughness overheated zone, small linear energy is better.
When welding Q345R steel of carbon content on the high side, for the hardening tendency increases, the content of martensite increases, it will cause the string cable energy cold cracking tendency increase, embrittlement of overheated zone also become serious, this situation is offline energy partial bigger is better.
