I. OBJECTIVES At the end of the lesson, the learners are expected to:
1. Weld carbon steel plates in flat groove (1G) position
2. Conducts visual inspection not exceeding allowable tolerances
specified by welding codes/ standards.
3. Use appropriate Personal Protective Equipment (PPE)
4. Perform proper housekeeping (5S)
A. Content Standards The learner demonstrates an understanding of the concepts and
underlying principles in Shielded Metal. Arc Welding (SMAW).
B. Performance Standards The learner independently performs Shielded Metal Arc
Welding (SMAW) processes based on market standards.
C. Learning Competencies or Explain the core concepts and principles of Shielded Metal Arc
Objectives Welding (SMAW)

IV. PROCEDURES
A. Reviewing previous lesson The teacher will ask about the following questions.
or presenting the new lesson 1. What are the parts of the groove weld?
2. What is needed to be done to avoid unacceptable weld?
B. Establishing a purpose for Let the students answered the jumbled words to form a word.
the lesson Direction: Arrange the jumbled letters in order to form a word.
GLAS - SLAG
ITYORPOS - POROSITY
REDUNTUC - UNDERCUT
PALREVO -OVERLAP
CKCRA - CRACK
Answer Key:
1. C, Defects
2. D, Rectify
3. E, Distortion
4. A, Porosity
5. B, Inclusion
C. Presenting examples/ instances of The teacher will show a video presentation of how to weld carbon
the new lesson steel plate.
2. At the 3/32” root gap insert electrode without flux in the root
joint
3. Put tack weld at both ends of the flat bar at 75 amperes setting
of the welding machine.
D. Discussing new concepts and The learner will conducts visual inspection not exceeding
practicing new skills #1 allowable tolerances specified by welding codes/ standards.
Directions: Read the statement carefully and identify what is
being described or defined. Choose your answer from the words
inside the box.
Undercut Excess Penetration
Lack Fusion
Burn-through Cracks
8. EXCESSIVE SPATTER
9. EXCESSIVE CONVEXITY
G. Finding practical applications of What is the purpose of using the welding codes in welding?
concepts and skills in daily living
The purpose of each of the welding codes is to have a uniform way to
approach welding that reflects the best practices developed and
proven to work overtime. They have the effect of improving welder
skill, equipment, and processes. The result is growth in the profession
when it comes to skill, quality, and welder efficiency.
