7. Guide Questions:
1.What is the picture all about?
2.What is observation of the weld profile as
shown in the picture?
3.What do you think will be our lesson
today?
8. Objectives:
At the end of the lesson, the student will be able to:
1. analyze and evaluate the proper welding techniques for achieving a clean
and even finish;
2. demonstrate a positive attitude towards welding safety by following proper
safety procedures;
3. apply the proper welding techniques to create a strong and effective weld
joint using stringer beads.
9. Terms:
Weld- Join together (metal pieces or parts) by
heating the surfaces to the point of melting
using a blowtorch, electric arc, or other means,
and uniting them by pressing, hammering, etc.
10. Terms:
bead - A type of weld, typically used for initial
process development, produced in a single
thickness of the material to be welded.
11. Terms:
Stringer bead - A narrow, straight weld bead
that is created by moving the SMAW electrode
straight along the weld joint.
12. Discussion Stringer Beads
Stringer beads welding is a commonly
used welding technique in various
industries such as construction,
manufacturing, and automotive.
13. It involves welding a continuous line along
the joint with a single pass. The purpose
of welding stringer beads is to provide
additional strength to the weld joint. It is
also an efficient way to weld large metal
sheets as it requires fewer passes
compared to other welding techniques.
14. To properly weld stringer beads, it is
important to maintain a steady arc
length, angle, and speed. This helps to
ensure that the weld is even and effective.
It is also crucial to properly clean and
prepare the metal sheets for welding to
achieve a clean finish.
