Welding Innovation Vol. XV, No. 2, Consider Direction of Loading When Sizing Fillet Welds Practical Ideas for the Design Professional by Duane K. Miller, Sc.D., P.E. Design File The traditional approach used to design a fillet weld assumes that the load is resisted by the weld’s throat, regardless of the direction of loading. Experience and. WELDING RESEARCH SUPPLEMENT TO THE WELDING JOURNAL, JANUARY, Sponsored by the American Welding Society and the Welding Research Council Cluster Porosity Effects on Transverse Fillet Weld Strength Relaxed radiographic inspection standards are recommended to allow greater porosity levels, when porosity alone is present, for fillet welds carrying static loads BY E. P. .   The fatigue strength of load-carrying fillet welds is, in most codes of practice, performed neglecting the influence of bending in the weld throat section. However, some commonly applied structural details give rise to significant bending in the weld throat section.

    The method should provide a basis for achieving a quantitative weld sizing in fillet weld design for structural applications. The paper starts with a brief description of major issues associated with strength data interpretation using the conventional shear stress formula given in AWS B which is widely used by various industries.

Comparison between two types transverse fillet weld on the Cited by: 1. fillet weld may be transverse to the axis of the weld, inclined to the axis or parallel to the axis.

The stress dis­ tribution in the weld and its static re­ sistance vary materially with the rela­ tive orientation of load and weld axis.

Most of the basic investigations on the static strength and behavior of fil­ let welds were conducted duringFile Size: KB. This report is the result of a major study on the influence of both main plate thickness and of attachment size on the fatigue strength of joints with transverse non-load-carrying fillet welds.

In particular, it defines the extent to which the size of the attachment might influence the thickness effect in such joints. A description of the comprehensive test program recently conducted at the University of Alberta to investigate the strength and behavior of transverse fillet welds is then presented.

This study deals with the fatigue life assessment of the transverse fillet weld and transverse fillet weld on weld fatigue specimen of the offshore steel SG2+M with a thickness of 10 mm. These specimens were joined using gas metal arc welding (GMAW) with ER80S-N1 filler metal of mm in diameter and mixed gases of 80% Ar + 20% CO2 as the consumables.

Fillet welds with S View other design data (BS ): Non-preloaded ordinary bolts - Grade bolts with S was investigated. Tests were conducted on longitudinal and transverse fillet welds and fillet welds oriented at 45° to the loading direction.

The specimens were prepared using the flux cored arc welding process, a Behaviour of transverse fillet welds book more commonly used in high production shop welding, and filler metals with and without a specified toughness. Higher toughness.

However, the lack of an analytical method to relate the strength of fillet welds to the angle of loading has led to a reluctance to utilize the increased weld strength for other loading angles. Designers have taken a lower-bound approach basing the strength of fillet welds on the strength of longitudinal fillets regardless of the loading direction.

1. Introduction. The static behaviour of welds has been studied extensively ever since welded joints became popular in the early 20th century. In the s, transverse and longitudinal fillet welds were recognized to define the upper and lower bounds, respectively, of the resistance of fillet welds; see for instance and Kulak noted that also the deformation capacity of the.

Fatigue is the most common cause of failure in welded structures and components, accounting for around 90% of failures, and usually design stresses in repeatedly loaded structures are limited by the fatigue strength of weld details, which can be very low (Fig.

1. Introduction. Fillet welds are common connection elements in structural joints such as beam-to-column joints. A vast amount of experimental data concerning fillet welds under quasi-static load conditions can be found in the literature, as the literature review by Miazga and Kennedy shows.

However, hardly any studies are concerned with the behavior of fillet welds under severe impulsive. The second reason for this trend is due to the fact that fillet welds can retain much of their strength after exposure to elevated temperature.

Further experimental research on post-fire fillet welds is needed to accurately evaluate the residual behavior of fillet welded connections after exposure to elevated temperatures.

Conclusions. The ductile behaviour of a large-scale simulated fillet welded double lap joint subjected to tensile loading was studied experimentally by means of a strain gauge technique.

Observations of elastic-plastic strain and ductile tearing throughout the weld zone up to ultimate failure were obtained in more detail than had been achieved by other.

Fillet Weld – A weld of approximately triangular cross section that joins two surfaces approximately at right angles to each other in a lap joint, T-joint, or corner joint. In this report, the static strength and behavior of transverse fillet welds are studied theoretically.

An approximate solution based on the theory of elasticity is reviewed and supplemented by an. Fillet welds loaded only by transverse forces exhibit considerably greater strength than those loaded only by longitudinal forces.

Current design standards in North America generally base the strength on the minimum value obtained in the longitudinal direction and consider that the strength is independent of the direction of loading.

Design weld resistance calculated by CBFEM is compared with the results of CM. The results are presented in Tab. The study is performed for two parameters, length of the weld and effective throat thickness, in three weld configurations: for the transverse weld, parallel welds, and a combination of transverse and parallel welds.

Design of a Fillet Joint. Transverse Fillet Weld. Transverse Fillet welds are designed for tensile strength. For strength calculations, the section of fillet is assumed to be a right angled triangle, with hypotenuse making equal angles with the two sides as shown in Figure transverse fillet weld and double transverse fillet weld are used for analysis.

Weld joints form an important part of pressure vessels, they are highly essential for structural integrity of the system. Typical welds are done on flat surfaces and their strengths are well catalogued for reference. The behavior of the weld model was adapted for the load resistance of welds or weld groups covered in codes rather than true weld behavior from experiments.

The model was verified on analytical models for behavior of welds in ENAISCand CSA S Though a fillet weld may be subjected to direct stresses, it is weaker in shear and therefore the latter is the main design consideration.

The fillet weld design clauses in AISC Section J(a) permit the use of a so-­called “directional strength enhancement factor” for fillet welds (i.e.

the “ + sin θ” term in Equation J2-­5), which enables the weld strength to be enhanced when the direction of loading is non-­parallel to the axis of the weld. Strength of Aluminum T-Joint Fillet Welds New design considerations are proposed for T-joints loaded in both transverse and longitudinal directions BY C.

MARSH ABSTRACT. A theoretical study of the strength of fillet welds is presented. Results are reported for tests on T-joint fillet welds. t 1 shear stress in the plane of the throat area transverse to the weld axis [MPa] The load-deformation behaviour of fillet welds is illustrated in Figure 6.

It is clear that an end fillet weld is considerably stronger than a side fillet weld. The difference is actually larger than one would expect from the calculation methods described here.

The “directionality increase,” or “ increase,” is specified in AISCSection J(b) (AISC, ), which says: “For fillet welds, the available strength is permitted to be determined accounting for a directional strength increase of ( + sin θ) if strain compatibility of the various weld elements is considered.”.

This directionality increase is a result of.Assessing Transverse Fillet Weld Fatigue Behavior in Aluminum from Full-Size and Small-Specimen Data.
