A thermal-metallurgical-mechanical model for laser welding

Dec 01, 2016 · In the present work, a conical heat source model with the parameters Z T = 6 mm, Z b = 0, R T = 2 mm, and R b = 0.6 mm (shown as Fig. 2a) was selected to represent the heat input of the laser beam welding. The locations at which the equivalent stress was measured and the area used to measure phase fractions after welding are also shown in Fig. 2b. E6013 carbon steel welding electrode J421 J38.12 Global E6013 welding electrode carbon steel welding rod China supplier Introduction:E6013 welding electrode is rutile-based carbon steel electrode. It has very good welding usability that enables it to perform all-position welding, operates on AC/DC, removal of slag is easy, has stable arc and also has very good bead appearance.

Influence of welding sequence on residual stress

Jul 01, 2021 · 1. Introduction. H-section steel members feature (i) excellent bending resistance and (ii) high ratio of strength to weight, and have been widely used in bridge engineering, building structure, offshore platforms and shipbuilding industry [, , ].During the fabrication of complex or large-span structures, different H-section steel members are often assembled utilizing welding technique. Numerical and Experimental Investigations in Laser Welding Jul 06, 2018 · The experiments of laser welding for steel and magnesium alloy in an overlap steel-on-magnesium configuration were carried out, the effect of adding Sn- foil on microstructure and mechanical properties of the weld were investigated, and numerical simulations of laser welding with/without Sn-Foil were also finished. A good agreement between the experimental results and numerical simulations for

Structural Steel Connections, Joints Details

Basic of Welding Structural welding is a process whereby the parts to be connected are heated and fused with a molten filler metal. Upon cooling, the structural steel (parent metal) and weld or filler metal will act as one continuous part. The filler metal is deposited from a special electrode.
