How is the price of welding work calculated, factors influencing the numbers

The professional path of a home welder is quite simple: the purchase of the first welding machine, the first repair, the first attempts to do the job efficiently, and after a while the first customers. It is at the last stage that the welder needs an estimate. An estimate for welding allows you to thoroughly calculate your expenses and income. In addition, the customer will have more confidence in you, since you will be able to provide him with transparent calculations.

There are many ways to determine the price of welding work: from the “by eye” estimation method to painstaking calculations. In this article we will tell you in detail how to evaluate your welding work so as not to lose money. We will also tell you about the factors influencing the price, valuation methods, and teach you how to perform simple calculations.

Calculation formula

Where twork is the time you spent working;

td is the time you spent traveling to your workplace (an optional item in the calculations);

ST is your hourly work rate;

Zd - your costs for gasoline (optional item in the calculations);

Zmat - the quantity or cost of your consumables;

AO - depreciation of your welding equipment (depreciation is taking into account the natural wear and tear of the equipment).

This method of calculating the cost of welding work is extremely simple and allows you to evaluate the work for both a production welder and a home craftsman. But keep in mind that this is the simplest formula. With its help, the estimate for welding will be undetailed and primitive.

What influences pricing

To calculate the estimate correctly, you need to understand what factors influence pricing. In simple words, what affects the final cost of your work. There are many factors, but we will highlight the most basic ones that apply to any type of welding.

The first factor is the volume of welding. This is logical; the amount of payment directly depends on the amount of work. But in addition to volumes, the complexity of the welding process, the type of welding chosen and the number of consumables used in welding must be taken into account. Agree, fast arc welding with electrodes is several times cheaper than semi-automatic welding using tungsten rods and gas.

Later we will tell you which formula to use in order to correctly calculate your welding work. Using the formula, you can set the optimal tariff for welding work. In the meantime, let's talk about methods for assessing welding work.

Welding work

To create a permanent connection between two or more metal elements, welding work is performed. Depending on the method of influence, welding can be arc, gas, laser, plasma, electroslag, etc.

The most popular are gas welding works. New interatomic bonds are formed in this case by gas-flame exposure of the metal and heating it to the melting temperature. No less common is electric arc welding with a coated electrode. It allows you to connect both small and large parts into single structures. For operations with stainless steel and non-ferrous metals, argon-arc welding is used on special semi-automatic machines.

Work evaluation methods

Before you learn how to do the math, familiarize yourself with methods for estimating welding costs. After all, in addition to mathematical calculations, there are other methods. This knowledge will be useful both to home welders who want to make estimates, and to industrial craftsmen who are tasked with independently estimating the cost of their work.

There is no uniform classification of methods. But we will highlight the main ones, which are most common and easy to use.

Visual assessment

The simplest assessment of the cost of metal structures is visual, or “by eye” (as home craftsmen often call it). This is a very unstable and controversial method, but it is the most accessible of all and does not require any knowledge at all. Often, this method is used in their work by beginners or craftsmen who make simple metal structures (for example, greenhouse frames).

In such cases, the master takes into account the time and materials spent, and also evaluates his customer. If the latter looks wealthy, then most likely the master will ask for a higher price.

There is also a hybrid of visual assessment and calculation. Everything is simple here: the cost of the metal (which is often estimated just “by eye”), which was required for the manufacture of a metal structure, is taken and multiplied by 2. Again, a rather primitive method, but quite effective if welding is not your main income.

Mathematical calculation

The most common method. We have already talked about it earlier. To make a mathematical calculation, special formulas are used. The estimate is most often generated on a computer in a special program.

We would like to tell you separately about an interesting technique that allows you to quite simply calculate tariffs for your work. The essence of the technique is to break down all the components of welding so that they can be easily assessed. First you need to determine the cost of the metal and consumables necessary to carry out welding work in an industrial or home environment.

Let's summarize these indicators. We get the amount that needs to be written down. These are our main expenses. Next, we determine how difficult the welding will be (conventional arc welding or resistance welding to be performed, for example). Sets the cost (the more complex the welding, the more expensive it is). The labor intensity of production and the time spent on work are also taken into account. This is overhead.

Now let's sum up overhead and basic expenses. This is the cost of welding. You need to add profit on top or factor it into overhead costs in advance. Calculating the cost using the mathematical method is quite simple and does not require special knowledge.

Next, we will tell you how to calculate the cost of welding using a simple formula.

Varieties

The following types of electric welding are distinguished:

1. Manual arc . It is easy to implement and does not require complex technical support. Suitable for welding stainless steel and ferrous metals only.
2. Welding using TIG technology . Makes it possible to work with vector non-ferrous metals and alloy steels.
3. Semi-automatic . This is a modern and high-quality type of welding. Often used by home craftsmen. The filler material is supplied automatically. The work is simple and of high quality.
4. SPOT . It is used in car service centers when carrying out body repairs. Requires the use of sophisticated equipment. It is used extremely rarely at home.

Based on the material being worked with, welding can be:

Depending on the type of equipment used, welding can be carried out using:

• Welding transformer.
• Welding MMA rectifiers.
• Equipment operating using an inverter circuit.

Welding machines can be:

• Ordinary, without additional functions.
• With the “HotStart” option (facilitates initial ignition).
• With the “AntiStick” function (prevents the device from overheating).
• With the “ArcForce” option (prevents the electrode from sticking to metal surfaces).

Depending on the performer, welding work can be carried out:

Methods for assessing the welding process

Before performing mathematical calculations, it is necessary to define methods that differ from numerical characteristics. In addition to formulas, there are other methods that will allow you to better understand the entire welding process.

Information is needed not only by those who prepare estimates for their home. When working in production and independently calculating the price of your work, the information described in this article will be useful.

How to calculate the cost of welding work

After purchasing a welding machine from an amateur, sooner or later the first orders from outside will appear. Enough for those you know to know that welding seams have begun to be of acceptable quality, the first people willing to use a welder will appear. And here it becomes necessary to calculate the cost of welding work. The best option is to draw up an estimate. It allows you to accurately take into account all cost items and inspires confidence among customers, since all calculations will be transparent.

There are many ways to determine the cost of services for welding work: from determining the approximate cost by analogy with the previously completed volume to precise verified calculations. Below we discuss all the methods available to the welder, including drawing up an estimate for welding work. The material will help you correctly determine the final cost and avoid unpleasant mistakes.

What determines the cost of welding work?

To competently draw up an estimate, you will need to understand the basic principles of its formation, that is, know what factors influence pricing. There are a large number of objective circumstances that have a direct or indirect impact on the formation of the final cost of services. But at first it is enough to know the basic principles.

The main factor is the volume of work. This is logical, since the longer it takes to complete a task, the higher the cost of the services provided. In addition to volumetric indicators, it is necessary to take into account qualitative ones - the complexity of the work, the type of welding, the quantity and types of consumables that need to be used during the work process.

For example, electric arc welding will be much cheaper than semi-automatic welding using a tungsten rod in an inert environment. Below is a formula that will make it much easier to determine the cost of welding services for metal workpieces. It is great for determining the tariff for a specific type of work or the cost of the entire volume.

But first you need to familiarize yourself with generally accepted valuation methods.

How to estimate the cost of a welder's work

Before proceeding directly to the calculations, you need to familiarize yourself with the options for estimating the cost of work.

It is important to understand that in addition to the mathematical approach, there are other ways to determine cost.

This knowledge is in demand among different categories of specialists: both among home craftsmen and among production site managers who independently determine the cost of services.

There is no single register of all existing methods. But it is worth paying attention to the main ones, which are most often in demand in practice.

Visual assessment

The easiest and fastest way to determine the cost of welding work is “by eye”. This is a relative method and the result largely depends on the master, or more precisely on his vision of the process.

But it is the simplest and does not require any special knowledge other than understanding how to implement the task.

Most often, this method is used by welders to calculate the cost of manufacturing simple structures.

In this case, the specialist takes into account the cost of materials and evaluates his contribution to the project. The final cost depends to some extent on the customer's solvency. If he looks like a wealthy person, then there is a high probability that the price will be somewhat inflated.

Another option is a symbiosis of visual assessment and calculation. Its principle is simple: the cost of work is equal to the cost of materials.

The welder roughly estimates the quantity and price of metal needed for the job. Then the result is multiplied by 2, and the amount is presented to the customer as final for the finished structure.

A fairly primitive method, but at the same time in demand among different categories of welders.

Mathematical calculation

The most common way to determine the cost of welding work. Based on the use of a special formula. Most often, the estimate is calculated by a PC operator who uses a specially developed algorithm (program).

A fairly simple and very accurate method that gives the welder the opportunity to independently determine the price for his services deserves special attention. It consists of breaking the process down into many simple steps that are easy to evaluate. At the very beginning, it is necessary to determine the amount of costs for materials, including consumables. Let these be the main expenses.

The result obtained is summed up and recorded. After this, the complexity of the welding work is determined and the price of the services is determined. The time spent on completing the work should also be taken into account. All this can be called overhead costs.

Now it's time to add up the basic and overhead costs to determine the final cost of the project. In some cases, it is advisable to add the planned profit to the obtained result, as is done in enterprises.

Formula for calculating the cost of welding metal structures

• twork – time spent on work;
• td – indicates the amount of time spent on the road to the object (place of work) and back (the item is not mandatory for calculation);
• ST – rate per hour of work;
• Zmat – the amount spent on consumables;
• Zd - the cost of gasoline or other fuel, a ticket or carrier services spent on arriving at the place of work (facility) - is not a mandatory item for calculation;
• Ао – the amount of expenses associated with depreciation (wear and tear) of the welding machine and auxiliary equipment (equipment).

How much did it cost to renovate a new building?

This calculation method allows you to fairly accurately calculate the cost of the finished metal structure. It can be used both in production and by amateur welders. However, it should be borne in mind that this is not the most detailed and accurate calculation formula. For technologically complex operations, there are more complex calculation algorithms that take into account all the nuances and all types of costs.

Conclusion

Using the above calculation methods, you can determine the cost of most technological operations for welding metals.

It is advisable for novice specialists to use the formula given in the article or the visual assessment method, provided that similar work has already been performed previously.

Well, for those who have been providing welding services for a long period of time, it is best to combine several calculation options so that the final value is as weighted as possible.
