Xu K, Zou B, Wang Y, Guo P, Huang C, Wang J () An experimental investigation of micro-machinability of aluminum alloy using Ti (C 7 N 3)-based cermet micro end-mill tools. J Mater Process Technol 30()–27 Figure 1 illustrates the basic experimental set-up: a Hobart DC SAW machine; an ultrasonic plastic welding machine (frequency levels at 15 and 20 kHz); and a horn made of aluminum, known as a ‘cational horn’, which reduces the stress and risk of cracks developing. Table 1 lists the welding condition and nominal composition of the.

A similar residual stress distribution has been reported by Ahn et al. () in AA laser welded T-joints, where the lower level of residual stress seen in the workpiece side with first weld. Three weld groove shapes of type V-groove, X-groove and U-groove are studied here.
The effect of groove shape is studied for two different thicknesses of 6 mm and 10 mm. The diameter and length of the pipes in all models are the same and equal to mm and mm, respectively, using the same material properties in all by: The weld root has a stress concentration, and the stresses near the weld root in the 20 steel are larger than those in 0Cr18Ni9 steel, making the weld root become the most risk zone for SCC.

This Specification has been based upon past successful usage, advances in the state of knowledge, and changes in design practice.
The experimental set-up involved robotized gas metal arc welding (GMAW), performed on U-groove and double-V weld preparation cut into 50 and 75 mm-thick steel plates. Half of the welds were robotically hammer-peened after each weld layer, except for the root pass. Weld Metal That part of an arc weld that was completely molten at one time during welding.
28 Weld Pool The molten metal, prior to its solidification, under and adjacent to the arc. Weld Reinforcement Weld metal in excess of the quantity required to fill a joint. Weld Root The region of a weld pass where the underside of a weld bead meets the 5/5(29). The radius used to form the shape of a J or U-groove weld joint.
Groove Type. The geometric configuration of a groove. Gouge to Sound Metal (GTSM) The process of back gouging to a depth to where sound weld metal, previously deposited from the other side, is achieved so that a weld with complete fusion through the root is obtained.

A slot weld is similar to a .Aluminum has relatively stable and pre-dictable properties. Therefore, it should be possible to meet specific requirements established in AWS D While the code does not state how to achieve specific results, it does provide the requirements for aluminum weld design, qualification (of welding procedures and welders), fabrication, and inspection.
