The welding personnel then can locate the marking and weld identification and weld each piece to finalize the structural section. SSPC-SP 8, P&O Dave Hansen, co-owner and production manager of Hansen Steel Services, Santa Fe Springs, Calif., said that the company mostly just grinds the scale to remove it from spot areas that call for only Q235 Steel Q235A Q235B Q235C Q235D Equivalent, Q235 Steel (Q235A Q235B Q235C Q235D) Q235 steel is a plain carbon structural steel which is widely used in China, Q235 material in Chinese standard GB/T 700 is divided into 4 quality grades:Q235A, Q235B, Q235C and Q235D; Density of this steel is 7.85 g/cm3, tensile strength is 370-500 MPa; yield strength is 235 MPa (data are for steel bar or steel plate diameter 16mm). Q345 steel property and specification are equivalent to Q345 steel property and specification are equivalent to A572 standard. The major benefit of Q345 steel is its mild temper, easy to form and weld.Q345 steel is one kind of Chinese standardized low alloy, equivalent to A572, medium tensile strength steel made with a hot-rolling process, used for a number of manufacturing p.

The T-welded joints were made by joining the web and panel plates via CO 2 gas shielded Welding - Steel ConstructionMost welded connections in building and bridgework use fillet welds, usually in a Tee configuration. They typically include end plate, stiffener, bearing and bracing connections to rolled sections or plate girders, and the web to flange connections on the plate girders themselves. These are relatively simple to prepare, weld and test in normal configurations, joint fit-up being the principal

Q345 steel specification:Q345 steel belongs to 16Mn steel grade, usually it is produced in hot rolled state, hot rolled steel plate, hot rolled steel coil/sheet, it has comprehensive mechanical and welding property, as it shows good performance in structural purposes, it is widely used as welding structural part in manufacturing of ship q345d steel tubeQ345 Steel Specification and Equivalent Standard. Q345 is low alloy structural steel with good mechanical properties, low temperature performance, plasticity and good weldability, it is mostly used in low pressure vessel, oil tank, vehicles, cranes, mining machinery, power stations, mechanical parts, building structure, general metal parts, Q345(E) steel plate is always delivered in hot rolled The welding performance of GB/T 1591 Q345D steel plates The impurity S and P content of GB/T 1591 Q345D steel plates are low, so the low temperature impact performance of Q345D steel is good. From the welding point of view, less impurity elements of the parent material is beneficial to control the welding hot crack. Of course, since the parent material chooses Q345D material, which is more expensive than Q345B. The application purpose of GB/T 1591 Q345D steel plates is special, so welding
