q345d steel for welded structure dimension

#TITLE# |KOBELCO - KOBE STEEL, LTD.

Fillet weld sizes must be large enough to carry the applied load, but the specified fillet weld size should not be excessive to minimize welding distortion and costs. AWS Dl.l (Structural Welding Code Steel) specifies the minimum fillet weld size for each base metal thickness:e.g. 6-mm size for thickness over 12.7 up to 19.0 mm. AWS Dl.l
