High cutting performance is realized by welding cobalt HSS of the cutting edges to the strong spring steel body. The non-uniform arrangement of cutting edges eliminates vibration during drilling. Non-uniformly arranged cutting edges are adopted for the HSS hole saws with diameters of 21 mm or more.
High Effective FE Simulation Methods for Deformation with high accuracy, three dimensional 8-nodes solid elements are used for modeling the shape of the weld groove. And then, for modeling the movement of weld heat source, heat input elements are generated step by step in the calculation considering the welding speed. In this model, there are 30 elements in the welding c- dire tion.
Nov 30, 2018 · The parts subject to the greatest stress were made of high-strength steel, but the welding was still spot welding. The problems of overlapping edges and the risk of corrosion remained. The biggest breakthrough came with the use of butt-joint laser-welded sheet metal, which finally allowed the use of diversified steels without the drawbacks of
Hollow sections - Hot-finished, seamless or welded hollow high contour accuracy and possible restrictions in edge radius, straightness, Twist and rectangularity Outer diameter 50 x 30 mm to 500 x 300 mm Wall thickness up to 20/25 mm Material and condition of delivery according to EN 10210 / S 235 JRH / S 355 J2H / S 355 NH. Certifications and admissions Welded tubes; Precision steel tubes
Investigating Welding Distortion of Thin-Plate Stiffened Mar 25, 2021 · In industry, thin-plate metal structures are often strengthened by longitudinal and transverse stiffeners using welding process. To investigate welding deformation in thin-plate steel structures, a small-scale thin-plate stiffened panel structure as shown in Fig. 1 was fabricated by gas metal arc welding (GMAW) in the current study. The base metal is Q235 steel, while the wire is ER50

High-speed welding using the 25 kW laser was confirmed. Furthermore, the effect of preheating on increasing the welding speed was investigated using pipe fabrica-tion line with the plate thickness of 10 mm carbon steel. Only the edge of the steel plate was heated by the high frequency heat source.
Weld orientation effects on the formability of tailor Apr 01, 2020 · Tailor welded blanks of thin sheets with different thickness 1.2 mm and 1.4 mm of the similar low carbon steel material (St 14) have been produced by fabrication stir welding experimentally and numerically in different orientations to evaluate the formability.
