Revealing Internal Flow Behaviour in Arc Welding and Additive
ARTICLE https://doi.org/10.1038/s41467-018-07900-9 OPEN Revealing internal flow behaviour in arc welding and additive manufacturing of metals Lee Aucott 1, Hongbiao Dong 2, Wajira Mirihanage3, Robert Atwood 4, Anton Kidess5,10, Shian Gao2, Shuwen Wen6,11, John Marsden6, Shuo Feng2, Mingming Tong7,12, Thomas Connolley 4, Michael Drakopoulos4, Chris R. Kleijn5, Ian M. Richardson8, David J. Browne7, Ragnvald H. Mathiesen9 & Helen.V. Atkinson2,13 1234567890():,; Internal flow behaviour during melt-pool-based metal manufacturing remains unclear and hinders progression to process optimisation. In this contribution, we present direct time- resolved imaging of melt pool flow dynamics from a high-energy synchrotron radiation experiment. We track internal flow streams during arc welding of steel and measure instantaneous flow velocities ranging from 0.1 m s−1 to 0.5 m s−1. When the temperature- dependent surface tension coefficient is negative, bulk turbulence is the main flow mechanism and the critical velocity for surface turbulence is below the limits identified in previous theoretical studies. When the alloy exhibits a positive temperature-dependent surface tension coefficient, surface turbulence occurs and derisory oxides can be entrapped within the subsequent solid as result of higher flow velocities. The widely used arc welding and the emerging arc additive manufacturing routes can be optimised by controlling internal melt flow through adjusting surface active elements. 1 United Kingdom Atomic Energy Authority, Culham Science Centre, Abingdon, Oxfordshire OX14 3DB, UK. 2 Department of Engineering, University of Leicester, Leicester LE1 7RH, UK. 3 School of Materials, University of Manchester, Manchester M13 9PL, UK. -

Tiny Vise Edge Clamps Truly Exert Down Thrust Force on the Workpiece, to Prevent It from Lifting
+44 (0)1204 699959 [email protected] www.hyquip.co.uk/web/index TINY VISE ™ EDGE CLAMPS BODY: 1018 STEEL, CARBURIZED-HARDENED, BLACK OXIDE FINISH THRUST WASHER: 1144 STEEL, HEAT TREATED, BLACK OXIDE FINISH FLAT-HEAD SOCKET SCREW: STEEL, BLACK OXIDE FINISH An important clamping development! These mini edge clamps grip the side of a workpiece to keep the top clear for machining. Patented design features a slotted countersink to provide strong, reliable clamping force with the easy turn of a hex wrench. These compact clamps are ideal for fixturing multiple parts, small or large. Each clamp has both a serrated face (for maximum gripping) and a smooth face (to avoid marring finished parts). These clamps look so simple, but work amazingly well, with major advantages over earlier designs. Flat Jaw Patent number 5.624.106. Made in USA. (Reversible, Serrated or Smooth) Clamping force is applied by positive screw action with the easy turn of a hex wrench (not with an unreliable, unsafe eccentric cam as Clamping force is applied by positive screw action with used in other designs). A high-strength Flat- the easy turn of a hex wrench. Head Socket Screw engages a mating offset countersink to exert strong clamping force. Much more durable than other designs. Only Tiny Vise Edge Clamps truly exert down thrust force on the workpiece, to prevent it from lifting. A thrust washer underneath the clamp engages a mating offset countersink to provide downward action. Patented design features a slotted countersink. Available in a wide range of sizes, from a miniature #8-32 thread size, up to a powerful 1”-8 thread size with 2500 lbs clamping force. -

Notes on Using the Height Gage
3. Lifting of the base from the reference surface Notes on using the height gage When setting the scriber height from a gauge block stack, or from a workpiece feature, the base may lift from the surface plate if excessive downwards force is 1. Keep the column, which guides the slider, clean. If dust or dirt accumulates used on the slider, and this results in measurement error. For accurate setting, on it, sliding becomes difficult, leading to errors in setting and measuring. move the slider slowly downwards while moving the scriber tip to and fro over the gauge block surface (or feature). The correct setting is when the scriber 2. When scribing, securely lock the slider in position using the clamping PG is just felt to lightly touch as it moves over the edge of the surface. It is also arrangements provided. It is advisable to confirm the setting after clamping 25 necessary to make sure that the surface plate and height gage base reference because the act of clamping on some height gages can alter the setting surface are free of dust or burrs before use. slightly. If this is so, allowance must be made when setting to allow for this effect. 3. Parallelism between the scriber measuring face and the base reference surface should be 0.01 mm or better. Remove any dust or burrs on the mounting surface when installing the scriber or lever-type dial indicator before measurement. Keep the scriber and other parts securely fixed in place during measurement. 4. If the main scale of the height gage can be moved, move it as required to set the zero point, and securely tighten the fixing nuts. -
