What You'll Learn
Welding and welding symbols
Lincoln Electric's book on how to read shop drawings with a special reference to welding and welding symbols is an excellent textbook that is easy to read and detailed. It is a good training tool for students in a structured welding training school. The book covers the basics and provides general structural information on welding and welding symbols.
Welding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion. Welding symbols are used on engineering drawings and blueprints to detail the type of weld to be executed, its size, and its location. These symbols are graphical representations that communicate the type, size, and other specifications of the weld to be performed. They are essential for providing clear instructions to welders and ensuring consistent and accurate welding across a project.
The American Welding Society (AWS) has developed a set of standard welding symbols that are commonly used in the industry. These symbols include a reference line, an arrow, a tail, and various other elements that indicate specific information about the weld. The reference line is the foundation of the symbol and is used to indicate the type of weld, such as a fillet weld or a groove weld. The arrow points to the joint or area where the weld is to be made, and the tail extends from the reference line and provides additional information such as the weld size, contour, and finish.
By using these standard welding symbols, Lincoln Electric's book provides students with the knowledge to interpret and understand the specific instructions conveyed in shop drawings. The book likely covers the different types of welds, such as arc welding, which uses a power supply to create an electric arc between an electrode and the base material, melting the metals at the welding point. Understanding how to read and interpret welding symbols is a critical skill for anyone involved in welding, ensuring that projects are completed safely, effectively, and to the required specifications.

Arc welding
There are various types of arc welding processes, including gas tungsten arc welding (GTAW), shielded metal arc welding (SMAW), and gas metal arc welding (GMAW). SMAW is also known as manual metal arc welding (MMAW) or stick welding, and it is one of the most common types of arc welding. In SMAW, an electric current is used to strike an arc between the base material and a consumable electrode rod or stick. The electrode rod is made of a compatible material that is covered in a flux, which gives off vapors that act as a shielding gas and provide a layer of slag to protect the weld area from contamination.
GMAW, commonly referred to as MIG welding, is a semi-automatic or automatic welding process. It uses a continuously fed consumable wire that acts as both the electrode and filler metal. An inert or semi-inert shielding gas is flowed around the wire to protect the weld site from contamination.
GTAW is a non-consumable electrode process, which means that the electrode does not melt and add filler material to the weld. This process can use either direct current (DC) or alternating current (AC). With DC, the polarity of the electrode determines the depth of the weld, while AC results in medium-penetration welds.

Welding certification
There are various organisations that offer welding certifications, each with its own focus and recognition within the industry. One of the most prominent and widely recognised certifying bodies is the American Welding Society (AWS). The AWS offers a general Certified Welder program that is accessible to anyone with a talent for welding, regardless of their previous educational background. This program provides transferable credentials to professional welders who can demonstrate the required skills through a strictly performance-based test. The AWS also offers multiple certifications within the Certified Welder program, allowing welders to expand their skill set and cater to a wider range of welding jobs, including structural steel, petroleum pipelines, sheet metal, and chemical refinery welding.
Other notable certifying bodies include the ASME, which provides certification for working on boiler and pressure vessels, and the API, which has specific codes for welding gas and oil pipelines. Additionally, local governments may have their own certification requirements, such as the NYC DOB license, which mandates specific AWS or DOT certifications.
To obtain a welding certification, individuals can opt for different paths. Some choose to attend trade schools or welding academies, where they receive structured training and prepare for certification exams. Others gain experience through on-the-job training, working for companies that offer in-house certification upon demonstrating proficiency. It is worth noting that maintaining certification often requires periodic renewal and proof of continued competency, such as submitting Maintenance of Welder Certification forms or retesting at specific intervals.
In conclusion, welding certification is a valuable asset for any welder, whether they are just starting out or have years of experience. It provides credibility, enhances career prospects, and ensures that welders meet industry standards. With various certifying bodies and programs available, welders can choose the path that best suits their needs and aspirations, ultimately contributing to their professional growth and success in the welding industry.
