Welding and welding in the building are two important cases in the operation of connecting different parts in industrial buildings and residential buildings. By permanently connecting metal parts, welding helps to create strength between the parts and maintain the safety of the building. Mentare also temporarily connects the parts to each other and after drying, the parts will be permanently connected. One of the production services of Dalfa Group is welding and mantare. In this article, we will examine the application of welding in construction, introducing various products in this field and welding services.
Welding in the building
Welding is used as one of the most important methods of connecting metal parts in the construction industry. This method uses heat and pressure to create a permanent connection between metal parts. For welding in the building, the following two main methods can be used:
1- single point welding
In this method, two metal pieces are connected to each other by using a welding point. This method is used in the welding of freight and railway parts.
2- Acoustic wave welding
Using sound waves, metal parts are connected to each other. This method is used for welding thin and narrow metal parts.
Mantare in the building
Mantare is used as a temporary method to connect metal parts in buildings. After drying, this method connects the parts permanently. Mantara in the building includes the following two main types:
1- Normal mantara
Ordinary Mantara is used in construction as a temporary adhesive for joining metal parts. After some time, the mantara dries and the pieces are permanently attached.
2- Thermal furnace
Thermal welding connects metal parts using heat. This type of mantara is used for parts that need a strong and stable connection.
The application of welding in the building
Welding is used in construction to create strong and stable connections between metal parts. These methods are used in all kinds of buildings, including industrial, commercial and residential buildings. Below we mention some types of use of welding and mantara:
1- Cargo buildings
In load-bearing buildings such as bridges, metal structures, beams and columns, welding is used to connect metal parts to each other. Welded joints between metal parts provide high strength and resistance to bending and tension forces.
2- Metal buildings
Buildings that use metal for their structural components; Such as frames, doors, windows and metal walls, welding and mantara are used to connect metal parts and create strong connections and high strength.
3- Piping
One application of welding is in piping systems. in buildings that include piping systems for water, gas, electricity, and heating and cooling systems; Welding and welding are used to create strong connections between pipes and metal parts used.
4- Air conditioning systems
In buildings that use air conditioning systems such as air ducts and air ducts, welding is used to connect metal parts and create leak-free connections.
5- Safety and fire fighting systems
Safety and fire fighting systems are used to maintain safety and prevent fire in buildings. In these systems, welding and brazing are used to connect metal parts of safety systems such as cooling systems and fire alarm systems.
6- Installation and connection of equipment
Installation and connection of equipment is also one of the types of welding applications. Welding is used in buildings to install and connect equipment such as elevators, electric towers, electrical panels and other industrial equipment.
The use of welding in buildings, as an effective method of connecting metal parts, plays a very important role in the strength and stability of buildings. The correct and high-quality use of these methods increases the useful life of the building and ensures the safety of the residents.
Welding services in the building
Welding and brazing services in the building play a very important role in the connection of metal parts and the strength of buildings. Using different techniques and methods, welding specialists are able to connect metal parts and create strong joints. Below are some of the welding services in the building:
1- Welding of structural metals
This service includes welding of structural metal parts such as beams, columns and bridges. Welders connect metal parts using appropriate methods such as electric arc welding, tig welding or argon welding so that the building can withstand bending and tension loads.
2- Welding of decorative metals
In buildings, there is often a need to weld decorative metals such as doors, windows, stairs, fences and other aesthetic elements. Welders use proper and careful methods to connect metals and provide beautiful connections and proper strength.
3- Mentoring services
Pickling is a surface modification process that is used to remove defects, impurities and unwanted particles from the surface of metals. This process is usually done after welding so that the metal surface is clean and ready for dyeing or other coating methods. Fertilization is done using chemical solutions or mechanical methods such as washing with a reel, scraping and drying.
The use of welding and welding services in the building is very important to create strong connections, structure strength and improve the safety of the building. It is better for these services to be performed by skilled and experienced professionals in order to meet the relevant requirements and standards.
