A construction project involves creating various structures of different sizes, complexity levels, and purposes. In any case, whether it is a small, simple structure such as a house of one’s own or a large, complex one such as a bridge, dam, or manufacturing plant, we need to implement it and need to buy them from a reliable welding item suppliers in Bangladesh.
The most important factors to consider in this industry are structural integrity and durability. For this reason, the construction industry uses a vast amount of metals in the building process. In addition, a large amount of this quantity is used to construct structural frameworks. In this area, welding plays a very important role in the construction industry.
In the construction industry, welding technologies are used for fusing various metal components to make structurally sound metal frameworks. Furthermore, it can also be used to create and maintain non-structural components. In some instances, welding used for the construction of buildings is prefabricated in a shop environment, whereas in other instances, it is done on-site on a construction site.
Therefore, today we are going to share about welding item suppliers in Bangladesh along with everything you need to know about welding in construction industry.
What Is Welding In Construction?
As the name implies, welding is nothing more than joining metals together. By comparison, nails are used to join wood together, mortars are used to join bricks together, and welding is used to join metal! Welding is not only a big deal in the world of construction, but it is essential to developing the world’s infrastructure. The majority of metal products that you use every day are welded in some way. As one of the most valuable technologies in the history of the world, it played a huge part in the industrial revolution and was the backbone of military forces worldwide.
Since welding has become necessary in manufacturing, automotive, and construction, many people have developed welding skills. Welders are generally needed to work in the industries mentioned, but welders can also carry out stand-alone construction projects, which makes them even more valuable. Therefore, they can save money and customize the design of whatever final product they’re looking to create since they don’t have to hire anyone else.
Getting a better understanding of construction welding would be beneficial to anyone aspiring to become a metalworker or welder. For more information on how to do that, keep reading.
The Purpose of Welding
The basic purpose of welding needed in building construction is to join two elements together and to provide a firm connection between them. The majority of welding jobs are done using metal or thermoplastic materials with a durable filler material used to bind the components together. The welding process is used to build many modern structures, including skyscrapers, cars, ships, airplanes, and other machines.
Builders have used other methods in the past for joining metal pieces together. Alternatives to welding include soldering, brazing, and riveting.
Common Methods Of Welding
To use the appropriate welding method in different situations, metalworkers need to be familiar with different types of welding. In general, more than one welding type is required to fuse metals or thermoplastic materials. The following are the most common types of welding you should be aware of, from preparation to the final touches:
Tack Welding
A tack weld is performed by welders when they want to hold metals in place while they are welding. The purpose of this type of welding is to join materials for a short period of time and only need soft weld spots. During the welding process, welders need to avoid pressing too hard so that the welded points become hard to break.
In addition to ensuring the alignment and strength of the material, tack welding is also used to ensure alignment. To start with, welders should always consider the quality and type of the metals they will be welding in the first place. The durability of the connection and the number of welded spots required during welding are determined by these attributes.
Shielded Metal Arc Welding
There is also a term called stick welding that refers to this process. It is similar to tack welding but instead of using a stick or rod, this method uses a stick or rod to join materials together. As an alternative, workers in this case use an electrode flux coated metal rod along with a component to be welded and a flux coated metal rod. When the rod is melted together with the workpiece, a weld is created.
Gas Tungsten Arc Welding
An electric arc is used by the worker in order to accomplish this task. As opposed to using a metal stick, a tungsten-based electrode is used instead of a metal rod when welding metals. Workers may use a filler material as part of the process or may not use a filler material at all. Due to the fact that tungsten does not burn off or dissolve, those working in aeronautics and auto repair shops prefer to use gas tungsten arc welding.
Gas Metal Arc Welding
To fuse metal components together, a shielding gas is used in conjunction with an electrode for gas metal arc welding. Moreover, this type of welding is also known for its ability to prevent contamination of the parts being welded. This method is used by a lot of welders for the joining of aluminum and steel in cars.
Flux-Cored Arc Welding
There is a continuous feeding system that is often used for thick and heavy metals, and this method involves a hollow tube that is constantly filled with flux. This type of welding also welds an electrode to the parent material, similar to the previous two welding methods mentioned.
How Construction Welding Works
Welding Preparation
Before a welding job can be completed, workers need to make sure that the metals to be welded are free of rust, grime, and grease, especially on the portions to be welded. It is common practice for welders to clean the pieces of metal with cotton cloths or high-pressure washers if the dirt has hardened into dirt and rust as a result of welding.
Wearing Protective Gear
There are many welding processes that need to be carried out safely by the welders, such as brazing, joining, and cutting of materials. Workers in such situations are at risk of radiation exposure, sparks, fumes, and other welding-related hazards as a result of these situations. There are many factors that can cause damage to your eyes and burns caused by such factors. There is even a possibility that workers could be electrocuted in some cases.
Safety goggles are one of the most important safety equipment that welders should wear in order to prevent accidents from occurring during welding operations.
Setting Up The Workpiece And The Workspace
It is common for workers to set up a platform for welding before they begin the work. In spite of this, they should ensure that their workspace is as safe and clean as possible so as to prevent injuries and other problems in the future. Therefore, whenever a new project is to be started or progressed, it is necessary to carry out a scheduled cleanup.
Proper Rod Movement And Positioning
It is best to set the rods at a slanted angle, roughly 15 degrees below the vertical so that they can be seen clearly. In order for the rod to move in a straight line, it must be moved in a straight line. Also, the arc length should be neither too long nor too short in both aspects.
Hitting The Arc
A welder could either scratch or tap the electrode’s end and the base material’s end when welding. In order to ensure that the metal pieces are as well attached as possible, the welder will need to scratch and tap for a certain length of time. Therefore, it is recommended that the welder scratch or taps for a longer period of time, the stronger the bond between the metals.
Creating A Good Weld
Material strength as well as the strength of the bond between the two metals are determined by the quality of welding. Most of the time, good welds are characterized by the following characteristics:
- Uniform
- Often welded in a straight direction
- Doesn’t crack in the middle
- Completely fused
- Well-feathered into the parent material
- Has even ripples
As a matter of fact, welders refine their welds and beads by removing slag as well as other parts that are not properly welded for improved results.
Cleaning The Workpiece And Workspace
Welding should always include a process of cleaning before and after welds are made. As a result, there are fewer chances of post-work injuries and other problems as well. In most cases, workers or a team of cleaners use homemade cleaning solutions, such as baking soda for the removal of slags, flour for the removal of burnt marks, and peroxide for the removal of burn marks. When it comes to cleaning the finished workpiece, wire brushing is a common method that is used.
Benefits of Welding in the Construction Industry
Due to the benefits associated with welding, businesses that work in the construction industry are well-suited to make use of this process. The following are some of the benefits that can be derived from it:
Durability
In the construction industry, it is difficult to overemphasize the significance of structural integrity and durability since structural failure can result in the loss of life and a significant amount of resources. Despite this, structures created can weigh thousands of tons and are expected to last for hundreds of years. As a result of the high strength and durability of weld joints, there is no need for stakeholders in the construction industry to worry about structural integrity from a structural integrity point of view.
Efficiency
In any construction project, efficiency is crucial to saving money, resources, and time and reducing costs. Therefore, it is crucial that the processes involved in the project are as efficient as possible to ensure that the project is productive. There is no doubt that welding is among the most efficient methods for advancing construction efficiency. In addition to the fact that welding is, when used with the right equipment, one of the most efficient processes, there has been the incorporation of many other technologies to make the process even more efficient.
Flexibility
In the construction industry, there is a wide range of fabrication requirements that need to be met. Welding is an indispensable element in the construction industry for a wide range of reasons, one of which is its flexibility. Whatever the size, work environment, or project material, there is a suitable welding technique for it. For example, welded beams and columns with a length of 50 meters can be as strong as pipes with a diameter of 5 cm. Additionally, it is important to point out that the different grades of metal used in construction can all be welded together using the same technology.
Cost-effectiveness
The cost of welding relative to other manufacturing processes is relatively low when compared to many others. In addition, contractors and other industry stakeholders can save thousands of dollars in capital expenditures by simply buying high-quality welder equipment from a reliable company. Purchasing your welding equipment may be an option you should consider if you plan on using it on an ongoing basis for a long time.
The Welding Process in Construction Sites
There are two primary sectors in the construction industry that can benefit from all the benefits mentioned previously. Following is a list of these sectors:
Building
There is no doubt that the building construction sector is the most popular sector in the construction industry. It is important to note that welding is often used in this sector to produce residential, commercial, and industrial buildings and structures. It is important to note that during the construction of these properties, welders put in place structural frameworks by connecting steel I-beams, columns, footers, and so on to ensure that the walls, floors, and roof are all properly supported. Additionally, welding is also one of the most effective ways to provide firewalls, stairways, electrical conduits, ventilation pipes, plumbing components, and utilities within the building.
Infrastructure
Infrastructure construction is another sector in the construction industry that can maximize the use of welding processes in order to maximize productivity. A major part of infrastructure construction is the construction of bridges, dams, water supply systems, highways, and other related structures, which can be only stabilized through welding the structural components that make up the structure.
The Services Welders Provide To The Construction Industry
Structural and Non-Structural Systems Welding
As part of the structural framework of a building, welders connect steel I-beams, columns, trusses, and footers. Building floors, walls, and roofs are constructed by cutting these components to size, lifting them into place with cranes or construction jacks, and welding them together.
The welder can also weld nonstructural metal building components. It includes stairs, handrails, bridges between rooms, floor joists, steel framing studs, firewalls, and other large and integral components that cannot be bolted into place.
Electrical System Welding
According to the architect’s plans, a welder connects electrical conduit with steel tubing installed by a pipefitter. Therefore, electricity can be supplied to all building parts requiring electricity from an outside power source.
Besides protecting the wires from damage, this electrical conduit holds them together. Welders weld electrical conduit together by cutting it to size, bending it to conform to the room’s dimensions, and welding it together. Power supply boxes are connected to walls or wall studs in an electrical conduit.
An electrician connects the wiring to switches and plugs once the conduit is shaped, welded, and attached to the electrical boxes.
Plumbing System Welding
Plumbing and welders work together to install water supply and wastewater pipes in each building room. Potable water is brought into the building through the water supply pipes from a city or rural water supply system.
Water is removed from the building through the wastewater pipes and piped to a drainage system. Water supply and wastewater pipes are cut to size, welded together, and buried underground to keep them secure.
Heating System Welding
Pipefitters and welders work together to install fuel circulation systems that carry natural gas throughout a building for heating and cooking. These fuel pipes are cut to size and installed within the walls and floors in residential or commercial buildings.
An auxiliary ventilation system is installed alongside the fuel system to capture exhaust gases and expel them from the building. It is necessary to weld together the fuel and ventilation pipes so that leaks can be prevented.
