Shielded metal arc welding (SMAW): Shielded metal arc welding, which is also known as stick welding, is the most widely used process. The arc is struck between the metal to be welded and a flux coated consumable electrode.Section 501 Steel StructuresFor structures carrying railway traffic and for other structures when specifically designated, furnish the Bridge Engineer a full set of permanent reproducibles of the final Shop Drawings. 4.

These steels were developed as a result of a joint industry-academia research project and with the primary object of re-ducing the construction cost of steel bridges.
SN Steel for Building Structure. SN Steel usage : Structural Steel for Building. Type A (SN400A) Applicable for structural members and parts that do not exhibit plastic behavior, such as beam, in-fill beam, roof frame. applicable for, even if limited, structurally significant members welded in field.Specification 1060 I Supply, Fabrication and Delivery of , for welded structure ss400 bridge millFracture-Critical Member: a structural steel component of the bridge that is subject to tensile stress in the permanent condition whose failure could lead to a collapse of the bridge or a collapse of a bridge span.STRUCTURAL STEEL TERMS/ LAYOUT AND FABRICATION The structural shape referred to as a BAR has a width of 8 inches or less and a thickness greater than 3/16 of an inch. The edges of bars usually are rolled square, like universal mill plates. The dimensions are expressed in a similar manner as that for plates; for instance, bar 6 inches x 1/2 inch.
Remove all coating, rust, dirt and mill scale within one inch of the area to be welded prior to fit-up. Remove all slag, spatter and weld discontinuities between passes. Clean the completed weld of all debris, slag and spatter. Care shall be taken to not exceed 250° in the proximity of the Elastomeric Bearing material.Galvanized Steel Grating Bridge Deck GratingSteel Bridge FabricationThe methods employed in the fabrication of a bridge structure are as variable as the structure itself.

WELDING OPTIONS IN STEEL CONSTRUCTIONThus cost effective welding is important in steel intensive construction as reliability; durability and safety of the structure. These are ensured through the strength of the fabricated joints .The standard structural steel is having tensile strength of 410-430 MPa (min), and good weldability.Use Caution When Specifying Seal WeldsWhat is a seal weld?AWS A3.0, Standard Welding Terms and Definitions, defines a seal weld as: Any weld designed primarily to provide a specific degree of tight-ness against leakage. The purpose of a seal weld may be to contain a fluid either gaseous or liquid. In the mechanical and structural fields, seal welds are used most
