The texture and colors of the patina provides the unique appearance and character of a structure with significant age in significantly less time. Common weathering steel specifications used in structural fabrication include ASTM A242, A588, A606 and A847. Specifications common to bridge fabrication include ASTM A709 and AASHTO M270.Help welding calculation - WELDINGThe welding geometry factor F 2 depends on the relation effective heat input to plate thickness. Approaching the three-dimensional heat flux F 2 decreases for the case of a one-pass fillet weld on a corner joint and increases for the one-pass fillet weld on a T-joint. Therefore an adaptive calculation may be necessary here. The factors given above can be selected here.China Welded H Section Steel - China H Beam, H Shaped SteelWelded H beams.

The major effect of weld imperfections on the service performance of steel structures is to increase the risk of failure by fatigue or by brittle fracture. Types of welding imperfection can be classified under one of several general headings: Cracks. Planar imperfections other than cracks, e.g. lack of penetration, lack of fusion. Slag inclusions.
