MachineMfgSep 13,2020 welding steel plates#0183;1.Problems of welding of large thick plates and measures to solve them (1) Number and size of welded steel plates.It is made of 3 steel plates,with widths of 1,900mm,1,900mm and 1,050mm (2) Welding method and groove type.General thick plate welding methods are electro slag welding,submerged
cover steel plate (8 x0.6 cm) with weld size 6mm,the two strengthen patterns (labeled as A and B) are shown in Fig.2.Pattern A was to weld the cover plate to lower flange of the test specimen,where pattern B was to weld the plate to the upper and lower flanges.The tested beam is referred,throughout the paper,as BX-Y-Z Where:File Size 780KBAuthor Nashwa M.YossefPage Count 6Publish Year 2015Welding AR400 Plate - Lincoln ElectricAR400 is a quench and tempered steel and may be difficult to weld due its high strength and hardenability.The base steel around the weld rapidly heats and cools during welding,resulting in a heat affected zone (HAZ) with high hardness.Any hydrogen in the weld metal may diffuse into HAZ and may cause hydrogen embrittlement,resulting in delayed underbead or toe cracks outside of the weld.
Charpy impact testing did not show any major reduction in toughness of coarse grained HAZ on S355J2 or S460N steel plates.Acceptable weld metal toughness also could be achieved with appropriate welding consumables.A hardness survey of the welds did not indicate any abnormal effect of welding on the weld metalStructural Steel Connections,Joints Details The maximum size of a fillet weld is as follows Along the edge of a connected part less than welding steel plates#188;inch thick,the maximum fillet weld size (w) equals the plate thickness For other values of plate thickness,t,the maximum weld size is t 1/16 in.BMA Engineering,Inc. 6000 14
The plate is secured vertically and the weld will be made down the groove vertically,either from top to bottom or bottom to top.11 Figure 4 The effect of shielding gas composition on the weld penetration and bead shape for steel.11 Figure 5 (a) The plates were marked into test specimens according to AWS D1.1 and (b) the sections were
