Mar 13, 2019 · Laser-Welded Coils. A laser-welded coil (Figure 2) is a continuous coil of steel comprised of individual, separate coils of steel with varying thickness and grades. The basic process takes separate coils, prepares their edges for contiguous joining, and laser welds these together into one master coil.
Blanking questions have you on the edge?Reducing the damaging effects of fractures, burnishing, burrs, and rollover improves subsequent forming processes. The blanked edge condition can be improved by adjusting the punch and die clearance tolerance, shaving the area of the defected blanked edge, designing an appropriate contact profile of the tool and die, and understanding the mechanical properties of the sheet metal used.

Design for steel bridge construction - SteelConstructionfoTo ensure that a steel bridge design can be safely, economically and reliably executed (fabricated, assembled and erected), designers should be aware of the processes of fabrication and erection, the capabilities and limitations of the steelwork contractor and how the design choices affect those processes.This article provides guidance on design for construction:it generally follows the
Design of Shear key for Steel column - Structural Oct 18, 2007 · I am to design a shear key for a steel column of a braced bay in a pipe rack. Since there is a significant amount of shear at column base which is difficult to be borne by anchor bolts ,shear key has been envisaged. (rolled section or plates in + shape welded at the bottom the base plate )flexural stress of this element (shear key depth is
Nov 21, 2008 · A three-dimensional, I-shaped, flat one turn copper coil as shown in Fig. 4 was designed and fabricated for the electromagnetic impact welding of 1 mm thick aluminum sheet to 0.25 mm thick stainless steel sheet by using aluminum sheet as the driver sheet. The web of 5 mm wide and 70 mm long at the center leads to concentration of the current, thereby increasing the current density J

Gauer - Rolled Alloys, Inc.416 stainless steel is a free-machining martensitic stainless steel with 12-13% chromium that can be hardened by heat treatment to higher strength and hardness levels. In the annealed condition, it has
Aug 08, 2007 · Coil-end joiners use gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), plasma, or laser welding depending on the line's specifications. Pax's heavy-gauge line uses GTAW to reduce buildup associated with the weld joint and to eliminate any concerns related to the weld's hardness in relation to the stamping tooling.
Introduction to Welded Joints IntroductionThe welded joints provide maximum efficiency (may be 100%) which is not possible in case of riveted joints. 3. Alterations and additions can be easily made in the existing structures. 4. As the welded structure is smooth in appearance, therefore it looks pleasing. 5. In welded connections, the tension members are not weakened as in the case of

and Steel Institute and the Welding Re search Councilpublication of the paper was sponsored by the Structural Steel Committee of the Welding Research Coun cil. 1, the design formula can be generalized to include the additional shear force from Mi for an interior connection and the reduction in shear force due to the column shear V to
Structural and Plate Steel Terms Definitions Engineers EdgeSTRIP STEEL -- (Cold Rolled) A flat cold rolled steel product rolled to widths 2316/16 and narrower, under .250 in thickness, which has been cold reduced to desired decimal thickness and temper on single stand, single stand reversing, or tandem cold mills in coil form from coiled hot rolled pickled strip steel.
THE DESIGN OF CAST-IN PLATES - Steel ConstructionThe most common form of connection is a steel plate cast into the wall to which the steel beams of the floor structure can be connected. Shear studs are usually provided on the back of the plate to resist the vertical reaction from the floor beam. Axial forces in the beam are resisted by reinforcing bars which are generally welded to the plate
