Applications and Advantages in Tank Fabrication and Maintenance
In the fabrication of storage tanks, as in most other welding applications, there are two crucial processes that storage tank fabricators must carry out to ensure the final quality and durability of the tanks. They are weld preheating and post-weld heat treatment.
Preheating involves heating the material to be welded to a particular temperature before welding. This process reduces shrinkage by minimizing the temperature between the arc and the base material. It also removes moisture, lowers hydrogen, and slows the weld cooling rate. These reduce the risk of cracking, brittle welds, and failure of the welds. Preheating is crucial for storage tanks as they are to withstand high pressures during operation.
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
Pre-weld and post-weld heat treating is critical for many welding operations. Without proper thermal manipulation, welds and heat affected zones can have mechanical properties that are undesirable. Worse yet, inadequate heat treatment can result in cracks and devastating weld failures. While temperature and time are the primary concerns when heat treating a weld, the heating method should also be considered diligently when selecting a process. Induction heating is one of the most popular types of heat treating methods, and rightfully so. The benefits of induction heating are many, and Red-D-Arc has the equipment you need to successfully implement an induction heat treating operation for your projects.
The answer is often no, and here’s why…
Gas (oxy-acetylene) welders used to be the rock stars of welding. From shipbuilding to automotive manufacturing to steel forging, but that was then. Arc welding is a modern welding method that outmatches gas welding in almost every respect.
Arc welders use electric current generated by a transformer or a generator to produce a uniform, clean welds that almost never require finishing. This is not the case with gas welding. Gas welding operates using the heat generated by the ignition of a gas mixture (oxygen and acetylene) to melt the welding material or to simply fuse two parts together. This process often results in a bad surface finish. Gas welding can require additional work involving hours of grinding and polishing the welds.

How important is it to remove welding smoke from the work area? Ask a welder, or ask someone who has to work in the vicinity of welders working in enclosed or semi-enclosed areas.
I recall some years ago working on a Navy general cargo ship. The ship was was undergoing extensive renovations and the hold of the had four or five levels. My employer, a small repair yard in San Francisco, unfortunately did not take air quality in the work area seriously. There were more than 20 of us working in the hold, and some number of us were welders. From a distance you could see where the work was being done — smoke and fumes drifting up out of the hold! In those days, safety requirements weren’t always top of mind. OSHA and other regulations aside, taking care of your workers by providing a safe work environment is simply the right thing to do. Without them your business can never be profitable. By failing to provide a safe workplace, you may lose workers due to health issues and employee turnover or face consequences for not complying with standards.
“respirators are hot and uncomfortable, and many welders simply refuse to use them”
There are a number of ways to deal with welding fume issues. One approach is the use of respirators. I often wore one, but they are hot and uncomfortable, and many welders simply refuse to use them. They can be remarkably expensive, over the long haul, given that filters must be replaced daily. If the mask is a disposable type, the entire mask must be replaced daily.
Portable smoke extractors – sometimes referred to as smoke eaters – are a far better solution. They extract a higher percentage of the fumes than respirator masks and protect everyone in the work area, not just the welders. They can be moved around the job site and from one job site to another, but can also be set up at permanent work stations. These machines can help make sure that your work space is a place where people can get their work done safely. Your employees will thank you.
