The Effect of Weld Penetration on Blast Performance of Welded Panels

Abstract

A modified explosion bulge test method was used demonstrate the difference in performance of full-penetration (nominally 100%) welds and partial-penetration (nominally 70%) welds under blast loading. The welded coupons consisted of armour steel plate, Bisalloy BisPlate High Hardness Armour steel, welded to Bisalloy BisPlate80 steel with an austenitic filler material, TETRA S 20 9 3-G . If was found that full-penetration welds will withstand, without cracking, closer blasts, and correspondingly greater blast loading, than partial penetration welds. However, there may be some critical length and size dimensions of the incomplete penetration for which the blast performance of the welded panel is not adversely affected.
