Part of Unit: Oxy-Fuel Welding and Processes
Lesson Plan Overview / Details
By Justin Pickard
This lesson will take students through the basic concepts, principles, and safety of oxy-fuel Welding. This is lesson one of three for an Introduction to Welding course. Instructors will need to break instruction time apart using the discussion materials attached to all three lessons. The use of oxy-fuel equipment is a necessity for teacher demonstrations and student practice as well as for parts identification.
Please Note- Materials for this lesson will continue to be used for the remaining two lessons.
Oxy-fuel Welding is a critical process in welding instruction. The concepts and skills that are used can be directly related to other process and more complicated process. hand-eye coordination, and technique are critical components to being successful using oxy-fuel equipment. Introducing this process to beginning welders will help put them on track for developing high levels of welding and fabrication skills.

- Students will be able to describe all of the safety precautions for Oxy-Fuel Welding
Activities in this Lesson
- Why Welding is Important - Hooks / Set
After students come into the class, play the video clip (provided in lesson plan) of Jay Leno talking about his custom cars and the welding industry.
Welding is an important trade in the United States, and we need new people to join the industry. Having an advanced level of knowledge and skill can put you in a situation of working on exciting projects and paying you very well. The concepts, skills and techniques that are a part of the Oxy-Fuel process directly relate to those concepts, skills, and techniques in other processes in the industry. Having a mastery ability of this process will improve your skills and help you achieve great things in the welding industry.
- Getting Started - Lecture
Each student will need a copy of the Essential Information Sheet, and Oxy-Fuel Welding Note Packet (provided in lesson plan). Review the Essential Information Sheet with the class so that they are aware of the standards they will be working towards, the vocabulary they will be introduced to, the knowledge targets they will be expected to come away with, and the skill targets they will be expected to perform by the end of the unit.
Begin the power point discussion (provided). Students will follow along with the power point by filling out the Note Packet that directly corresponds to the power point. Take the students through slide 6. By this point you will have given them the basic information regarding the process, the principles and the safety involved with Oxy-Fuel Welding.
- Putting this Information to Use - Demo / Modeling
At this point, direct the students to take their notebooks (with additional paper) and put their safety equipment on. Once the class is ready to work in the shop, have the class gather around a station that you have set up for Oxy-Fuel Welding. Walk through the safety considerations of OFW, the process of turning on the equipment and describe the processes that are taking place during the procedure (relating it to the material they just wrote down in their note packet from the power point slides). By this time they have written down the information twice once with actual equipment in front of them, and once in the classroom) and have seen the pieces of equipment that the process utilizes.
Finish the demonstration by showing the class how to light the equipment, and run a stringer bead without rod and then shut the system down.
- Students Demonstrate Knowledge - Demo / Modeling
After demonstration have the students (by asking for volunteers, or random selection, or class calling back answer, etc) describe the safety concerns related to the OFW equipment/process. By pointing to the different types of equipment, have the class describe what is happening with the welding process at that point and time.
Direct the students to clean up the shop materials and return to the classroom.
- Ticket out the Door - Assessment
Back in the classroom, have the students put their Note Packets away. Pass out a 3” X 5” card, and ask the students to write down and answer
- Where does the heat from this process come from?
- What are two industries/or careers that use Oxy-Fuel Welding?
- What is the purpose of filler rod?
- Write down at least 4 of the 10 Safety Precautions
- Wrapping it Up - Closure
Let the students know that the information that they have gained today is going to be built upon in the coming days. Mastery of these skills early on will help to better develop your skills as a young welder.
Collect the note cards from the students as they leave. Utilize the answers to help gauge the effectiveness of the day’s lesson. Any segment that you feel needs to be re-emphasized you can discuss the following day at the beginning of the period.
- Assessment Types:
- Writing Samples, Observations,
Students will be assessed by using Checking for Understanding (questioning class periodically to evaluate the class's comprehension.
Students will use a writing sample (Ticket Out the Door) to demonstrate their knowledge competency
