Why is it important to have overlapping Stringer beads in fillet welds?

Why must the weld beads in padding be overlapped?

Overlapping beads are made by depositing connective weld beads parallel to one another. The parallel beads overlap, forming a flat surface. Overlapping beads are used to build up a surface and to make multi-pass welds.

When overlapping Stringer beads use a work angle of what degrees toward the first stringer bead to obtain proper tie in?

When overlapping stringer beads, use a work angle of 10 to 15 degrees toward the first stringer bead to obtain, proper tie-in. the tapping method.

When depositing overlapping welds on a pad of beads the new bead should cover the previous bead?

Each stringer bead should be about 2 to 3 times the diameter of the electrode wire. Each new bead should cover 1/3 ‐ 1/2 of the previous one. 6. Pause at the end of each bead to fill in the crater.

Is a stringer bead used to create a wider weld pool?

Stringer bead is used when a standard bead width is acceptable. is used to create a wider weld pool. It is formed by moving the torch or electrode holder from side to side as the weld pass progresses along the weld joint. Different movement patterns can be used; the crescent motion is one of the most popular patterns.

Why uniformity of beads is important in welding?

The target size of the weld bead is determined according to the workpiece thickness, weld length, weld joint type etc. In addition, the uniformity of the bead size is also important from the standpoint of appearance as well as strength.

What are stringer beads?

Stringer bead – A narrow, straight weld bead that is created by moving the SMAW electrode straight along the weld joint. A quality stringer bead should have good tie-in on both sides of the weld. … Fill – Also referred to as a fill pass, it is the amount of weld bead necessary to fill the weld joint.

Why is it important that the electrode and workpiece lead connections are tight?

Why is it important for the electrode and workpiece lead connections to be tight? Any loose connections will cause an increase in resistance in the welding circuit.

When weave beads are made the motion of the electrode is ____?

welding exam

Question Answer
a weld bead that is made with a side to side motion of the electrode is called a __________ bead. weave
The best method of striking an arc when using a transformer DC welding machine is the _______ method Tapping

When using weave beads on flat V groove welds keep the electrode angle at a zero degree angle with a ?

Terms in this set (10)

When using stringer beads on v-groove welds in the vertical position, keep the electrode at a 0- to 10- degree push angle with a – degree work angle.

How much should stringer beads overlap on a filler pass?

Filler passes are made with Stringer beads or weave beads. They should overlap enough so that the finished bead is smooth. Stringer beads usually overlap about 50% and weave beads overlap approximately 25%. Each weld bead must be cleaned before the next bead it started.

What would happen if an operator welder decrease the arc length?

Arc welding is a constant current process, but the arc length has an effect on voltage. Reducing the arc length will decrease the voltage, and this reduces the heat in the weld.
