Questions regarding the selection of welding electrodes for Q235B and Q345B welding

2017-05-25View Original

Thread Content

Regarding the welding of Q235B and Q345B materials, the relevant regulations specify the use of J426/J427 or J506/J507. How should one choose among them in practice? Some steel structure codes specify the use of materials with lower performance levels, namely J426/J427, while some pressure vessel codes require the use of materials with higher performance levels, namely J506/J507

Those with high requirements should choose the higher option; those with lower requirements should choose the higher one when the prices are similar.
