designing fillet welds for skewed t joints part 2
For angles between 60 and 80 degrees the designer has to account for the effective throat using the formula contained in Annex B D11. A weld preparation the weld prep is therefore.

In order to weld the full thickness of a plate and achieve the weld throat thickness required by design it is therefore necessary to cut away sufficient metal along the joint line so that the welding electrode has access to the root of the joint enabling the root pass to be deposited and then the remainder filled to complete the joint.
. Fillet Weld The required fillet welds are shown in Figure 8. See Annex II for formula governing the calculation of effective throats for fillet welds in skewed T-joints. Used to calculate the required fillet weld size for the far side weld.
Skewed T-joint fillet welds have either been qualified by analysis andor testing or are considered nonload carrying welds. Other welds include partial penetration groove welds. Fillet weld size shown in Table 10-14C on page 10-177.
Fillet weld that is. Typical welds capable of being measured with gauge 10 are welds 12 and 14 shown in FIGS. Depending on the skewed t.
The American Welding Society Structural Welding Code - Steel AWS D11 provides design and detailing requirements for skewed t-joints. Depending on the skewed t-joint geometry designers are required to define the required weld leg or effective throat size. Fillet Weld The required fillet welds are shown in Figure 8.
However many designers are unaware of the AWS D11 skewed t-joint requirements and apply typical 90. Depending on the skewed t-joint geometry designers are required to define the required weld leg or effective throat size. The American Welding Society Structural Welding Code - Steel AWS D11 provides design and detailing requirements for skewed t-joints.
The present invention comprises a gauge for measuring certain dimensions of welds at skewed T joints the gauge being broadly denoted by the numeral 10. W 1 20221 in. Consider the Transfer of Stress through Members Welding Innovation Vol.

Notice that the far side weld is less than the 5 16-in. W 1 20221 in. However many designers are unaware of the AWS D11 skewed t-joint requirements and apply typical 90.
The effective throat shall be the shortest distance from the joint root to the weld face of the diagrammatic weld see Annex I. Oenoral Construction Specification O-29C has been revised to clarity. Engineers and designers have been alerted to the AISCAWS requirements for limiting angles for skewed T-joints.
Notice that the far side weld is less than the 5 16-in. A tabulation of mea-. If the dihedral angle is less than 80 or more than 100 degrees it is a welded skewed T-joint.
Designing Fillet Welds for Skewed T-Joints Part 1 Lessons Learned in the Field. A series of equations can be used to. The effective throat shall be the shortest distance from the joint root to the weld face of the diagrammatic weld see Annex I.

Detailing fillet welds for 90-degree T-joints is a fairly straightforward activityTake the 90-degree T-joint and skew itthat is rotate the upright member so as to create an acute and obtuse orientation and the resultant geometry of the fillet welds becomes more complicated see Figure 1The greater the degree of rotation the greater the differ-. The term fillet weld is applicable to welds deposited on the joint with dihedral angles between 80 and 100 degrees.
Depending on the skewed t-joint geometry designers are required to define the required weld leg or effective.
