CN102744498A - Method for welding specially-thick high bridge s235jr steel plate width Submerged arc welding
The invention provides a method for welding a specially-thick high-strength bridge steel plate and belongs to the technical field of specially-thick plate welding. The test plate of the method adopts a symmetric narrow gap U-shaped groove form, is combinedly welded by using two efficient welding methods, namely gas shielded welding for priming and bottom filling, and double-wire submerged arc welding 5/5(22)Publish Year: 2012Author: , , , , , , , , , , Development of submerged arc welding method using hot May 02, 2014 · May 02, 2014 · In the fabrication of steel bridge, submerged arc welding (SAW) is widely utilized. In order to increase the efficiency for the production of welds, the increase in electrode such as SAW with multiple wire electrodes is effective. However, heat input also increases with increasing the number of electrode. The new welding method based on SAW method with one How is SpaceChem used in steel bridge fabrication?Spacechem has latest Auto CNC Steel Plate Cutting, Assembly, Robotic Submerge Arc Welding, Flange Straightening, Grinding, Die-penetration, Blasting, Painting, Testing and Quality Control for fabrication of Beams, Boxes for Bridges and heavy structures from prime quality steel plates.See all results for this question

What is a submerged arc flux and wire?
submerged arc. A variety of welding flux and wire designed to be paired together to meet any industry specific welding requirement.See all results for this questionWhen to use a bead in submerged arc welding?Submerged arc welding is most efficient if the joint can be filled with as few passes as possible. If, when working in mild steel, the workpiece can be turned over and if the material is not too thick, a bead is often applied from each side of the joint. If the basic material is an alloy steel, a multi-pass procedure is normally necessary.See all results for this questionWhich is more efficient submerged or submerged arc welding?Submerged arc welding is most efficient if the joint can be filled with as few passes as possible.
