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 root pass?
It is the first pass in a multiple weld joint.
How is it possible to identify a weld that has been made with too long an arc length?
A weld made with too long an arc length typically exhibits characteristics such as excessive spatter, inconsistent bead appearance, and poor penetration. The weld bead may appear wider and flatter, with a lack of fusion at the edges. Additionally, the heat-affected zone may show signs of overheating, leading to distortion or cracking. Overall, visual inspection and the quality of the weld can help identify issues related to arc length.
What is the method of arc shielding in SMAW?
Arc shielding in Shielded Metal Arc Welding (SMAW) involves the use of a consumable electrode that produces a protective gas and slag when it melts. This shielding effect protects the weld pool from atmospheric contamination, such as oxygen and nitrogen, which can weaken the weld. The electrode coating generates gases and forms a molten slag that covers the weld area, stabilizing the arc and enhancing the quality of the weld. Proper arc shielding is crucial for achieving strong, defect-free welds in various materials.

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.
What is pitch of a filet weld?
Pitch is center to center spacing of an intermittent weld.
How do you measure filet weld?
In a fillet weld, the leg and size are the same for the convex weld.
What term refers to the center-to-center spacing of intermittent filet weld?
Pitch
What is the filet weld size required for weldolets to main pipe joint?

What is the Five parts of a filet weld?

What is the difference between Full-penetration butt welds and filet butt weld?

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.
What is the ratio between the leg length and the throat thickness on a mitre filet weld with equal leg lengths?
it depends on the fillet welds dimentions and fit up requirements
