Video teaching of making splayed beam of steel structure

Web and flange are usually connected by continuous fillet weld, so the angle between flange plate and web is not acute, but there is arc welding. On the one hand, the fillet weld between the flange plate and the web plate is avoided, which makes the stiffening plate easier to be in place; More importantly, the weld of the stiffening plate does not directly contact with the fillet weld between the flange plate and the web plate, thus avoiding the welding stress concentration caused by the concentration of multiple welds.
