Welding works for metal structures: description of welding types and average cost

When there is a need for welding, in the first place, the question arises about the cost of this service. Prices for the use of welding services may vary depending on the type and volume of the order, and can be calculated from the length of the seam.

Of course, it is possible to carry out welding process and independently, but in this case there is a significantly reduced quality. Low quality welds are detrimental, as this can lead to structural instability or depressurization when it comes to pipelines.

Introduction

It is best to seek the help of welders, who provide private services, but we must not forget, that his qualification must be confirmed by the category.

You can also choose private companies, which provide a variety of welding services. Firms, which provide services for welding of metal structures, having a high reputation, qualified specialists, who know how to work with modern equipment and reasonable prices.

Types of welding

Methods of welding, this is a very important point, which should be taken into account when ordering the service. In particular, welding differs from each other in the degree of complexity and use of different types of energy. Each type of welding has its nuances, advantages in quality and application on various objects. Example, it is possible to allocate arc welding, which is most often used in production. Gas welding, usually, used on private sites.

Semi-automatic welding

Special electrodes are used when working with metals by means of arc welding. This is material, which in its structure consists of a wire covered with flux. The flux during welding melts and forms in the area of ​​the straightened metal, gas shell, which ultimately prevents the oxidation of the metal. in addition, special additives in the flux help to strengthen the weld. A similar principle of welding is used in the semi-automatic process.

Semiautomatic welding machine, differs primarily in the use of special wire, which is automatically fed into the work area. The wire is automatically unwound from the drum, moreover, unlike the electrode, it is not covered with flux. Protection of seams is carried out by receipt of any inert gas. Carbon dioxide is most often used, which protects the seams from oxidation. The use of this type of welding significantly improves the quality, and as a result seams do not demand, mechanical cleaning.

The cost of welding.

  1. The arc method is worth it 10-15 UAH for 1 see seam.
  2. The work of the semiautomatic device is worth it 15-25 UAH for 1 see seam.

Spot and multi-point welding

Spot welding is rarely used in private construction due to its high cost. Naturally, such prices for welding of metal structures are due to the high quality and complexity of the work.

Unlike the arc method, in spot welding several electrodes are used, which can melt and fasten metal alternately or simultaneously. Simultaneous creation of seams on all site of welding is called multipoint.

The only difference here is, that in the point model the current is applied gradually to one or two electrodes. In multi-point welding process, usually, current is supplied by an energy distributor to all electrodes at once. Overlay seams on metal structures in a similar way, requires special equipment and a highly qualified specialist.

Spot welding combines two processes at once. Almost simultaneously, the metal melts and increases the pressure. As the pressure increases, the hardness of the metal is overcome, due to which the necessary deformation at all necessary points of creation of a seam turns out. Using this process allows you to get quality and reliable seams, which in the end do not even require mechanical stripping.

The cost of spot welding varies from 40 to 50 rubles. When using a multipoint process, prices are doubled.

The cost of welding

Prices for welding services vary depending on the reputation of the company or the qualifications of the specialist. Basically, the cost of welding work on metal structures is calculated depending on the complexity and volume of the order. The price is usually taken per running meter or per seam. in addition, other times it is a question of carrying out works on welding of pipes or lattices, but not many firms have specialists, to take on such challenging tasks.

  • 100-600 rubles for welding one joint on the pipes;
  • 25-60 rubles when using argon arc welding.

Cost per running meter of the product:

  • 2800-3800 rubles inflated lattice;
  • 4400-5500 rubles arable play;
  • 2000-3000 rubles simple lattice;
  • 8000-10000 rubles decorative lattice.

When ordering welding services to create decorative products, furniture, racks for shops, not only the complexity of the work is taken into account, but also the order itself. Some clients may provide their own design sketches. Usually in the manufacture of standard structures, the cost per running meter is 1800-2500 rubles. If you have to create a metal structure according to the sketch, the cost increases to 15000-30000 rubles per running meter.

The cost of welding work in the manufacture of one running meter of fences:

  • 1500-2500 rubles of a simple fence;
  • 1300-2000 rubles portable fence;
  • 3000-5000 rubles of decorative fencing.

The use of welding services of metal structures in the production is relatively cheaper.

Here, usually, all work is carried out in bulk and the cost is calculated in tons of finished products. Wholesale work in the welding process as a result and reduces prices compared to the private market for services.

The cost of welding for the main types of metal:

  • 400-800 rubles per ton of channel;
  • 20000-50000 rubles per ton of pipes;
  • 20000-35000 per ton of steel sheets;
  • 20000-35000 per ton of corners.

Conclusion

For private companies or people, who just want to use welding services, everything is much easier, than at the global level. Here you just need to determine the type of welding required, and find professionals. As a result, only the question of prices remains open, which are constantly changing.
