Outcome: Identify the purpose and the proper use of personal protective equipment (PPE) including, clothing, and footwear while identifying the hazards from which they protect individuals.
The following document provides lists and tips for protective clothing for welders to use and wear.
The following documents include fire safety when welding.
You'll need a touch screen to try this welding simulator!
The following documents are about eye safety and conditions.
The following resources include welding safety on fumes and gases.
Welders face serious safety risks associated with intense light rays. These intense harmful light rays are emitted from the arc and the oxy-fuel flame. You must guard your body against these harmful light rays by wearing proper personal protective equipment. This equipment also helps protect you from grinding sparks, flying slag and weld spatter. You must also put up screens and warning signs when arc welding, cutting or grinding at work sites in the vicinity of the general public. Do not use any high gloss or shiny surfaces for screens, because reflected rays can be just as dangerous. The oxy-fuel torch, and the electric arc give off both visible and invisible light rays. This radiant energy can be divided into three types:
* visible light,
* ultraviolet rays and
* infra-red rays
The Welding Technology course provides students with an understanding of manufacturing processes and systems common to careers in welding and related industries. Topics include the interpretation and layout of welded and assembled-parts, reading blueprints and understanding welding symbols. Further topics included are the common welding processes found in industry, metal charcteristics and finishing processes dealing with welded parts and projects.
The owner and creator of this website is a journey person welder who also taught welding school. He retired and started making videos about everything that has to do with welding. The videos are of high quality and descriptions are clear. Great resource for how to's on many different welds and processes, general information regrading career pathways, etc.
Students learn about electrical connections, how they work and their pervasiveness in our world. They consider the usefulness of wireless electrical connections for connecting electrical devices. Morse code is introduced as a communication method that takes advantage of on/off states to transmit messages by electrical bursts sent via wires, light or sound. They learn the Morse code rules and translate a few phrases into Morse code. Specifically, they learn about a wireless connection type known as Bluetooth that can be used to control LEGO robots remotely from Android devices, which leads into the associated activity.
Students are introduced to the concept of electricity by identifying it as an unseen, but pervasive and important presence in their lives. They are also introduced to the idea of engineers making, controlling and distributing electricity. The main concepts presented are the science of electricity and the careers that involve an understanding of electricity. Students first review the structure of atoms and then learn that electrons are the particles behind electrical current and the motivation for electron movement. They compare conductors and insulators based on their capabilities for electron flow. Then water and electrical systems are compared as an analogy to electrical current. They learn the differences between static and dynamic forms of electricity. A PowerPoint(TM) presentation is included, with review question/answer slides, as well as assessment handouts to practice using electricity-related terms through storytelling and to research electricity-related and electrical engineering careers.
Students are presented with an overview of engineering and design. Various engineering disciplines are discussed in some detail using slides and an online video and website. The concept of design is introduced by presenting the basic steps of the engineering design process. Students learn that design is not necessarily restricted to engineering, but a general concept applicable to all walks of life. To strengthen their understanding, students are challenged to design a picnic for their friends by considering its various components as they go through the design process steps. This prepares them for subsequent design challenges such as those in the associated activities of this unit. A PowerPoint® presentation, pre/post quizzes and worksheet are provided.
Students learn about electric motors and rotational sensors. They learn that motors convert electrical energy to mechanical energy and typically include rotational sensors to enable distance measuring. They also learn the basics about gear trains and gear ratios. Students create a basic program using the LEGO MINDSTORMS(TM) NXT interface to control a motor to move a small robot. Then, through a 10-minute mini-activity, they make measurements and observations to test a LEGO rotation sensor's ability to measure distance in rotations. This prepares them for the associated activity during which they calculate how many wheel rotations are needed to travel a distance. A PowerPoint® presentation, worksheet and pre/post quizzes are provided.
This lesson introduces students to the major characteristics of robots. The associated activity uses the LEGO MINDSTORMS(TM) NXT system as an example. Before studying robots in more detail, it is important for students to consider the many items they encounter in their daily lives that are robots so they can explore ways engineers can utilize robotics to solve problems in everyday life.The activity also serves as an introduction to the LEGO NXT system so that students may utilize it as an educational tool in subsequent lessons and activities.
This video is an interview with an agronomist exploring the role and responsibilities that come with it.
In this tutorial we will learn what electric charge and current is and how electricity works.
Leave No Trace, or LNT, principles are a group of best practices for enjoying our wild spaces. In this video, Miranda talks about the seven principles of Leave No Trace and how you can follow them to leave the wilderness as beautiful as you found it.
