filet weld penetration cross section - Sections Of A Weld : Maine Welding Company


A cross section of a weld (particularly when etched) will show you the penetration profile of the weld, including the depth and width of penetration (see examples in Figures 3 and 4, which also name and highlight the various parts of a fillet and groove weld). To achieve the proper weld strength, all welding requires complete fusion to occur. 2.3.4 Complete Joint Penetration Groove Welds 2.3.4.1 Weld Size. The weld size of a complete joint penetration groove weld shall be the thickness of the thinner part joined. No increase in the effective area for design calculations is permitted for weld reinforcement. Groove weld sizes for welds in T-, Y-, and K-connections in tubular members.

Jul 29, 2019 · The dimensions of a weld may be added to a drawing in the following manner. Dimensions relating to the cross section of the weld are symbolized by b and are given on the left-hand side of the symbol. The cross-sectional dimension to be indicated for a fillet weld is the leg length. If the design throat thickness is to be indicated then the leg. ness of the fillet weld is 0.707ω, where ωis the weld size. The deep penetration of fillet welds made by the SAW process is recognized in the LRFD Specification Section J2.2a wherein the effective throat thickness is considered to be equal to the weld size for 3/8-in. and smaller welds, and equal to the effective throat thick-.

Figure 1 shows a cross section of a fillet weld, where the penetration profile can be seen. The welding variable that has the greatest effect on the degree of weld penetration is current (measured in amperage or amps). Quite simply, as welding current increases (i.e., more amperage), weld penetration increases and as welding current decreases. The following terms are used to describe the parts or sections of a weld: Fusion Zone (Filler Penetration). The fusion zone is the area of base metal melted as determined in the cross section of a weld. Leg of a Fillet Weld. The leg of a fillet weld is the distance from the root of the joint to the toe of the fillet weld.
