13.2.4 Welding Welding is the fusion or uniting of two pieces of metal by application of heat and the addition of filler metal of a composition similar to the pieces being joined. For highway structures, the heat is applied by an electric arc, and the weld metal is deposited into the work from an electrode. The processes usually used include: For Welded Structure S235jr Bridge With Standard Sizes Submerged Arc Welding - Image ResultsWelding of highway structures with an emphasis on steel highway bridges Explain AASHTO/AWS D1.5/D1.5M Bridge Welding Code and the AWS D1.1/D1.1M Structural Welding Code-Steel, including relationships to structural performance and design

This Standard specifies requirements for the welding of steel structures made up of combinations of steel plate, sheet or sections, including hollow sections and built-up sections, or castings and forgings, by the following processes:(a) Manual metal-arc welding (MMAW).(b) Submerged arc welding (SAW).(c) Gas metal-arc welding (GMAW or MIG), including pulsed mode.(d) Gas tungsten-arc welding (GTAW or TIG).(e) Flux-cored arc welding (FCAW).(f) Electroslag (including consumable guide) welding for welded structure s235jr bridge with standard sizes Submerged arc welding AS/NZS 1554.4:2004 Structural steel welding Welding of high strenThis Standard specifies requirements for the welding of steel structures made up of combinations of steel plate, sheet or sections, including hollow sections and built-up sections, or castings and forgings, by the following processes: (a) Manual metal-arc welding (MMAW). (b) Submerged arc welding (SAW). Boom Welding Innovation - Using Hybrid LaserTraditional Submerged Arc process typically requires booms to be welded together on both the inside and outside of the boom or with the addition of a backing bar, whereas the use of hybrid laser allows 100% penetration welding from a single side removing the need for a backing bar altogether.

This code covers the welding requirements for AASHTO welded highway bridges made from carbon and low-alloy con- structional steels. This 2002 edition contains dimensions in metric SI Units and U.S. Customary Units . CHAPTER 6. WELDED CONNECTIONS 6.1 INTRODUCTORY CONCEPTSshielded metal arc welding, and higher strength results. Other commonly used processes for shop welding are gas shielded metal arc, flux cored arc, and electro-slag welding. Quality control of welded connections is particularly difficult, because defects below the surface, or even minor flaws at the surface, will escape visual detection. Common pipe type-Q235B spiral steel pipes | ASTM A234 butt for welded structure s235jr bridge with standard sizes Submerged arc weldingQ235B spiral pipe is a commonly used raw material in spiral pipes.It is a spiral seam steel pipe welded with strip steel coil as the raw material and active double wire double-sided submerged arc welding. The main technical characteristics of the spiral steel pipe: During the forming process, the steel plate is uniformly deformed, the residual for welded structure s235jr bridge with standard sizes Submerged arc welding

In Submerged arc welding a power current is applied to a continuous wire electrode. This is generally much larger diameter than in MAG welding. The arc is struck when the wire electrode contacts the work piece. Protection of the weld is provided by slag, formed by the action of the arc on a powder covering the whole weld reaction area.

A blanket of granular fusible flux shields the arc.

High quality steel pipes are produced from three (3) manufacturing processes: Seamless, LSAW (longitudinal-seam submerged arc welding), and ERW (electric resistance welding). LSAW and ERW pipes are highly regarded for their numerous fields of application.
