SENSE level 1 GTAW provides entry level welders the knowledge they need to earn a Level 1 SENSE certificate in gas tungsten arc welding. Entry level welders are at Level 1 when they can perform routine tasks under close supervision.
Summary: The class “Welding Fumes and Gases Safety” helps students to understand the dangers of fume and gas generation in welding. The fume plume, a visible cloud of smoke rising from the molten metal, consists of complex metallic oxides and particles formed from the consumable and base metal. Shielding gases used in welding may also produce potentially harmful fumes. Exposure to fumes can be managed through engineering controls, ventilation, proper PPE, and adherence to exposure limits set by OSHA or other organizations.
After taking this class, the student will understand the potential dangers of welding fumes and gases, as well as the acute and chronic symptoms that may develop after overexposure. This class discusses how workplace practices and engineering controls can be used to control exposure, in addition to following Permissible Exposure Limits and using air-supplied respirators when necessary.
Summary: “Material Tests for Welding” introduces users to the types and purposes of welding material tests. Welding materials are tested to evaluate their properties, examine for discontinuities, and ensure the project meets welding code specifications. Testing can be destructive or non-destructive. Testing can also be used to classify metals according to their carbon content.This class includes lessons on non-destructive testing methods such as visual inspection, radiographic, ultrasonic, penetrant, and magnetic particle tests. Users will also become familiar with destructive testing methods such as the macro-etch test, fillet weld break test, guided bend test, and transverse tension test. After completing this course, users will be able to identify common material tests, the practical applications of destructive and non-destructive methods, and the advantages and disadvantages of each method.
Summary: “Overview of Weld Defects” provides a comprehensive introduction to the most common varieties of weld discontinuities and distortion. It illustrates the causes of each of the twenty different weld discontinuities and defects and suggests effective solutions. In addition, it presents an overview of six different kinds of cracks and demonstrates how to prevent cracking and distortion in a finished weld.This class is especially crucial for beginning welders who do not yet have the skills or knowledge to avoid many of the mistakes that the class illustrates. Beginning welders will find this class particularly useful because it defines the reasons why defects or discontinuities may occur as well as the ways in which welders may rectify them.
Summary: “Welding Symbols and Codes” describes how welding blueprints represent welding requirements. A weld is represented in a blueprint using a welding symbol. Welding symbols, which were created by the American Welding Society, include a reference line, arrow element, weld symbol or symbols, tail, and weld dimensions. When needed, the welding symbol will also have supplementary symbols and finish symbols.The welding symbol includes various components on the reference line to show the characteristics of the weld and provide specific instructions to the welder. After taking this class, users should be able to explain the many types of welding symbols and their characteristics, as well as the welding codes and specifications used in the welding industry.
Summary: "Introduction to GTAW” defines gas tungsten arc welding (GTAW), describes the tools used in GTAW, and discusses the various factors that should be considered when using GTAW. GTAW, or TIG welding, is a precise welding process that uses a nonconsumable tungsten electrode and inert shielding gas. GTAW can be used on a wide variety of metals, and can be performed manually or with the use of semi-automated or totally automated systems.GTAW gives the welder increased control over the weld, which allows for the fabrication of stronger and higher quality welds. The process can be complex and requires practice to master, but the improved weld quality is vital to certain applications. By the end of this class, users will be able to define GTAW, identify the tools used in GTAW, and describe the various GTAW processes and applications.
Summary: “Plasma Cutting” describes plasma cutting equipment and discusses the setup and operation steps for plasma cutting, gouging, and piercing. Plasma cutting is a precise and efficient cutting method that uses an ionized jet of gas to generate a high temperature cutting arc and can be done by hand or with the use of CNC machine.Plasma cutting is an increasingly affordable and popular method of metal cutting. Plasma cutting balances the lower cost of cutting methods such as oxyfuel with the higher quality of laser cutting methods. After this class, users will be able to define plasma cutting, identify the tools used in plasma cutting, and describe the various cutting applications and processes. Understanding the basic plasma cutting functions and processes is essential for users to make precise, accurate cuts safely and efficiently.
Summary: This class describes the welding characteristics of aluminum and explains how its properties affect each variable in the welding process.
Summary: “GTAW Applications” provides an overview of the practical applications of the gas tungsten arc welding process. It covers all parts of the process, including personal protective equipment, power supplies, polarity, amperage, electrodes, shielding gas, cups, starting the arc, filler metal, welding techniques, possible defects, and professional and industrial applications.“GTAW Applications” is essential for any welder who requires an in-depth understanding of GTAW. Its focus on application extends "Intro to GTAW" to the practical sphere, paving the way for hands-on learning of GTAW welding.
Summary: "SDS and Hazard Communication" focuses on communication methods about hazardous workplace substances and how they increase employee awareness and safety. Education, labeling, data collection, testing, and other communication methods detail the dangers of specific chemicals and offer methods of protection from physical and health hazards. OSHA requires that employers establish a written hazard communication program to communicate employee responsibilities, standard implementation, chemical hazards, and safety measures. Hazard communication programs must include a chemical inventory, specific labeling, SDS for each individual chemical, and training.After taking this class, users will be able to describe OSHA regulations regarding hazardous materials and SDS and their impact on daily workplace operations. Understanding these regulations is critical in maintaining workplace safety and efficient operation.
