How do you determine the minimum welding size?
The size of a fillet weld should be calculated by the designer of the welded structure, based on the nature and magnitude of applied loads, on the material and on the design basis.
What determines the proper size of a weld?
1. Fillet weld legs determine fillet weld sizes. Fillet weld sizes are measured by the length of the legs of the largest right triangle that may be inscribed within the fillet weld cross section. Fillet weld sizes determine theoretical throat.
What does welding depend on?
Many distinct factors influence the strength of welds and the material around them, including the welding method, the amount and concentration of energy input, the weldability of the base material, filler material, and flux material, the design of the joint, and the interactions between all these factors.
How do you determine the minimum size of a butt weld?
The minimum length of butt weld shall be:
- Equal to the thicker plate thickness.
- Equal to the thinner plate thickness.
- Two times the size of the weld.
- Four times the size of the weld.
What is minimum weld width?
b. Except that the weld size need not exceed the thickness of the thinner part joined. c. Minimum size for cyclically loaded structure shall be 3/16in [5mm].
What does weld size mean?
The leg length is usually designated as the size of the weld. The throat of the weld is the distance from the center of the face to the root of the weld. Typically the depth of the throat should be at least as thick as the thickness of metal you are welding.
What is minimum specified length of fillet weld?
What is the minimum specified length of fillet weld? Explanation: As per IS code, the actual length of fillet weld should not be less than four times the size of weld. If this requirement is not met, the size of weld should be one fourth of the effective length.
What determines the size of a fillet weld?
The size of a fillet weld is determined by its ‘leg length’. The figure is pretty theoretical – it depicts an equilateral triangle – whereas a real weld is never flat, and will be either concave or convex, and not necessarily equal-length legs. For strength calculations, we’re interested in the throat thickness.
In which factors weldability of metal depends upon?
Explanation: Weldability is dependent on five factors of the metal or alloying element. The factors being, melting point, thermal expansion, thermal conductivity, surface condition and change in the microstructure.
What should be the minimum length of the weld plate?
“The minimum length of a fillet weld shall be at least four times the nominal size, or the effective size of the weld shall be considered not to exceed 25\% of its effective length.”
