Why should convex weld faces be avoided?
Convex weld faces should be avoided because they can create stress concentrations that may lead to premature failure in welded joints. The raised profile can also hinder proper penetration and fusion, compromising the overall strength of the weld. Additionally, convex surfaces can complicate inspections and make it difficult to detect defects or ensure uniformity in the weld. Maintaining a flat or slightly concave profile promotes better load distribution and enhances the integrity of the joint.
What is the ratio between the leg length and the design throat thickness on a mitre filet weld equal leg lengths?
In a mitre fillet weld with equal leg lengths, the design throat thickness (T) is typically calculated as 0.707 times the leg length (L). Therefore, the ratio of leg length to throat thickness can be expressed as L/T = L/(0.707L) = 1.414. This means the leg length is approximately 1.414 times the design throat thickness.
How do you calculate allowances for weld gaps and weld shrinkage in order to attain overall global tolerances?
To calculate allowances for weld gaps and weld shrinkage, start by determining the specific tolerances required for the final assembly based on design specifications. Assess the anticipated weld shrinkage for the materials used by referring to established shrinkage rates, typically expressed as a percentage of the weld length. Add the calculated weld gap allowance, which accounts for the joint fit-up, to the shrinkage allowance. Finally, sum these allowances and incorporate them into the global tolerances to ensure that the final assembly meets the design criteria.
How do you calculate weld inches for pipe?
To calculate weld inches for pipe, first determine the total length of the welds required for the project. Measure the circumference of the pipe (using the formula π times the diameter) and multiply it by the number of joints or welds. For multiple welds, sum the lengths of all individual welds to get the total weld inches. Finally, if applicable, factor in the number of passes required for each weld to obtain the overall weld inches.
What does z mean in weld symbol?
In weld symbols, the letter "z" typically indicates a requirement for a "z weld" or a specific type of groove weld, often associated with a particular joint configuration or preparation. It may also refer to a specific dimensional requirement, such as the depth of a weld or a certain profile. The exact meaning can vary based on the welding code or standard being referenced, so it's important to consult the relevant documentation for precise interpretation.
How to do CONCAVE filet weld?

Leg or filet weld?
Leg of the weld. Fillet is the part you cut off e.g. a corner...
What parts of a filet weld are measured?
The distances from the root to the edges of the legs (toes) and the height of the crown are basic measurements. If the face is concave it might be considered.
How do you measure filet weld?
In a fillet weld, the leg and size are the same for the convex weld.
What is pitch of a filet weld?
Pitch is center to center spacing of an intermittent weld.
Why should convex weld faces be avoided?

What is definition of the under run in filet weld?
A fillet weld in any single continuous weldmay underrun the nominal fillet weld size specified by2 mm [1/16 in] without correction, provided that theundersize portion of the weld does not exceed 10% of thelength of the weld. On the web-to-flange welds on girders,underrun shall be prohibited at the ends for a lengthequal to twice the width of the flange.
Why is filet weld necessary while welding slip on flanges to a pipe end?
It is the only type of weld you can make to seal this type of joint. There are flange ends that can be welded onto pipe with a butt weld, but sockets and slip-ons must be fillet welded.
