Welding is a rewarding career, but work-related injuries can deter you; therefore, you must have the right knowledge about welding safety.
With the right welding safety precautions, welding as a career may offer an excellent income, job security, and even the opportunity to travel.
Some welders and the companies that employ them forget to follow the precautions, resulting in injuries that can be devastating. The Department of Labor estimates that in every a thousand welders, four of them will be fatally injured at some point of their careers. Because of this danger, there are numerous safety regulations you should always follow to help protect welders and those around them.
6 Welding Safety Tips
1 – Wear proper gear.
It is very crucial to have the right gear when you are welding. If you own a workshop, then you should ensure that your employees are completely covered. Every welder should wear flame-resistant clothing such as denim or wool. If cotton is worn, it should be treated to ensure that it is fire-resistant.
A welding jacket is an excellent way to help protect workers. Some may complain that welding jackets are too hot and too heavy to wear and will try to avoid wearing them. Many of the companies who make safety gear now make clothing that is lightweight yet still provides a great deal of protection. Newer styles allow welders more comfort and mobility.
Gloves are also essential for welding safety. In the past, the gloves were simply one-size fits all. Nowadays, gloves are designed with different sizes for different welding procedures. These new age gloves allow for welders to have increased maneuverability to work safely, yet efficiently. When it comes to shoes, boots, and high-top leather shoes offer the best for protection.
2 – Avoid the light.
Arc flash can damage the eyes. Always avoid exposure to the flash by wearing welding helmets fitted with a proper filtering shade to keep your eyes and face safe when welding. Select approved safety glasses with protective shields at the sides and ear protection to wear under the helmet. Also, go for a lens shade that is suitable for your welding application. You can use the OSHA guide to choose the best lens based on your welding procedures. Additionally, companies should install barriers or screens where appropriate to protect workers from arc flash.
3 – Avoid repetitive stress injuries.
Doing the same thing over and over again or being in the same position under the same strain for an extended period can frequently cause repetitive stress injuries. These kind of injuries have become a great concern to a lot of workers since they are severe enough to force a welder to give up his career. Workers should often take breaks to stretch. Managers should reiterate and stress that safe lifting techniques be practiced.
You can also avoid neck fatigue by using auto-darkening helmets. An auto-darkening helmet is lighter than the traditional fixed-shade helmet, and the worker is not required to look down to drop the hood frequently. Seconds saved between welds will allow for more productivity.
4 – Familiarize yourself with the equipment.
One of the most essential welding safety rules is to make sure that only workers who are adequately trained and authorized, use welding equipment. Many accidents occur because people use machines without the right training.
This often happens in home welding shops, where friends or family of the welder will try to work on a project themselves. It also occurs in professional settings when welders let others do their work or in the case of employers who wish to cut costs. Without proper training, increased incidence of injuries and property damage can be expected.
Additionally, everyone who operates a particular machine has to read the welder’s operating manual. It contains essential safety information, as well as information procedures that maximize the machine’s potential.
Ensure you read the welder’s operating manual.
5 – Proper ventilation.
Welding in a well-ventilated area that is at least 10,000 cubic feet with a 16-foot high ceiling. Place the welding equipment where you can get natural drafts or fans that blowin the fumes away from your face, or at least across it, but never straight into it. If the machine requires you to use a respirator or exhaust hood, wear the correct one to maintain clean breathing air.
6 – Don’t allow clutter.
Clutter is a welding workshop enemy. It is a significant cause of accidents such as fires since sparks can find more places to land and smolder. The working area should only have the equipment and tools that the workers are using.
To keep a workshop organized and safe, managers should consider labeling the places where each welding machine, tool, and equipment should be placed. Companies should also ensure that all welding cables are well-maintained. Then enforce the rules of keeping welding equipment and materials in proper places. Removing the clutter will help keep paths are clear and improve welding safety.

6 Tips to Improve Welding Safety | Red-d-Arc
A welding certification is a key component for a professional welder that comes with many rewards; not to mention higher salaries, better job stability, and higher job demand. The welding industry forms a critical part of the global industrial sector.
Some of the industrial applications of welding include shipbuilding; in the fabrication processes of different metals like aluminum and steel, as well as providing various components used in the manufacture of HVAC units.
To create quality welds, a person is required to hold a certification in different welding categories. Therefore, they are required to pass a welding test to ensure that they possesses the right skills for the job.
In welding, a certification may be equated to a crown worn by a king. It shows proof of your efficiency, effectiveness, and ability to match the job description and other unique tasks within a specific level of expertise. A welding test is conducted by an authorized and certified welding inspector. A welding professional who is certified in working on a specific position is not necessarily able to work on other positions.
Types of Welds
Industrially, welding technicians use two main common types of welds. They include:
- Fillet weld: Fillet welding involves joining two metals at a perpendicular position (at a right angle) or in a slanted angle. Fillet welds are also known as T joint or lap joint. Additionally, the two metals may also be welded in an overlapping position, which creates a triangular shape; used mainly in joining two metal tubes.
- Groove weld: A groove weld is used to join two metal plates. A cross-sectional perspective of a groove weld shows two metals joined at a right/ slanted angle, giving it an L or V groove.
Understanding the Types of Welding Procedures
To propel your welding career to higher heights, you need to understand the processes involved in welding. Welders also need to undergo extensive training programs to develop hands-on experience. These are some of the factors that make a professional and versatile expert.
In any training college you attend, you may choose to learn about any of the following four procedures:
Shielded Metal Arc Welding (SMAW)
SMAW is a type of welding procedure that requires you to adhere to a stick welding manual. The process relies on electricity to create an arch between the stick and the surfaces to be joined. The procedure is used in the construction and fabrication of steel and iron structures.
Flux-Cored Arc Welding (FCAW)
The FCAW procedure was formulated as an alternative to the SMAW process. It utilizes an automatic arc weld during the construction of different metal structures.
Gas Metal Gas Welding/Metal Inert Gas (GMGW/MIG)
GMGW/ MIG welding is the most common type of procedure in the welding industry. A shielding gas that runs along an electrode is used to heat the two metals to be joined. The method requires a constant flow of direct current and voltage.
Gas Tungsten Arch Welding/Tungsten Inert Gas Welding (GTAW/TIG)
GTAW/ TIG welding is used in joining two pieces of thick stainless steel and other non-ferrous metals. This method uses electricity and a tungsten electrode that produces the weld. It is a slow process and therefore requires a lot of skill and patience.
Types of Welding Certifications
Whichever procedure of welding you want to pursue, you must have the corresponding certification. A number/ letter system usually denotes that. For instance, in a 2G certification, the 2 shows the level position and the G stands for the gr0ove. Here are some types of certifications.
1G Welding Certification
As a 1G certified welder, you have to have the skills to create quality welds in the first position – flat position. Therefore, you weld the joint while looking down at it.
With a 1G certification, you can only handle welding procedures of joining metals at a flat position. The major challenge during a 1G test is that gravity makes the slag flow faster than the arc, which may cause poor quality welds due to cold lap and slag inclusion.
2G Welding Certification
Welders applying for a 2G welding test should be able to weld a joint moving from the left to right or vice versa while looking across the joint. It is a more advanced certification than the 1G test. Passing it means you can handle any jobs related to flat-position welding.
During this certification, welders are required to join two beveled plates with a first slow pass. The second layer is created rather quickly without quenching the first weld. That gives it the required quality.
3G and 4G Combo Welding Certification
While you may decide to take individual tests for both 3G and 4G certification, these two are typically combined. Excelling in the test combo shows you have the skills to meet any 3G and 4G jobs, including the others in the lower groove classes.
In 3G, both the plates and the weld axis are aligned vertically. In this position, you can either weld the joints from the bottom to the top, or starting from the top coming down. On the other hand, 4G welding requires skill sets that enable you to work on an overhead weld. Therefore, welders need to look up while joining overhead plates from the left to the right or the reverse.
5G and 6G Welding Certification
The 5G and 6G certifications feature a combination of tests that involve three positions: horizontal, vertical, and overhead. It is a type of certification required for welding pipes and tubes of small diameters; usually to be used in power plants and oil refinery industries. It is a complicated procedure because the horizontal position of the tubes involves a fixed 2G position as well as a 45-degree fixed position.
5G and 6G certifications are also used in the welding of larger pipes with bigger diameters. It is a line of work that calls for the knowledge of both 2G and 3G, where the pipe is fixed in a horizontal position and welded vertically using a recommended filler material.

Different Welding Certifications| Red-d-Arc
Originally built in the 1930s, the Grand Coulee Dam in Washington State has been undergoing a series of maintenance projects to ensure that it will continue to produce safe and reliable power into the future. One stage of the project required the heating of a 40-ft wide, 7-ft tall outer headcover of the turbine shaft to specific core temperature. In order to achieve this temperature, the engineers applied induction heating to one side of the workpiece.
Only when the opposite side of the workpiece reached target temperature could the maintenance engineers be certain that the required core temperature had been achieved. The team from Red-D-Arc provided induction heating systems and assistance with training and set up during this essential part of the maintenance process.
