Welding technical process

The basics of  best portable welding machine include the concept of preliminary preparation of a process plan. This will be a kind of guide to the competent implementation of the welding process.

The technological process of welding specific products will help to take into account all their features and nuances.

The description of the technological welding process is set out in a special document called a technological map. It can be attributed to a kind of normative document, which sets out the theory of welding operations. The technological process at the welding site, described in the map, is an indispensable assistant to the welder.

Example of the welding process:

 The guidance material in the form of a technological map should contain information about the brands of the parts being welded and recommendations on the choice of the method of their connection and spatial location. The welding process covers the requirements for the parameters set on the equipment used, the diameter of the electrodes used, recommendations for environmental protection, and setting the polarity.

 The technological process of welding a product contains information about the sequence of actions performed. It may also contain a calculation of the applied materials required for the implementation of this process. The technological map contains small sketches, which increases the visibility.

FEATURES OF WELDING PRODUCTION AT THE ENTERPRISE

In many industries, welding works are necessary, they can be found literally everywhere: from the repair of engineering communications to the manufacture of spacecraft. Therefore, the old welding enterprises continue to function and new plants are opened after them. At the same time, there is an increasing shortage of competent specialists who perform work efficiently and quickly. Strict requirements are imposed on new employees, which are constantly becoming more complicated.

But this is only one of the features, if we are talking about the production of welding works. In this material, we will tell you all the basics of welding production and tell you what skills a person who has chosen the specialty "welding production"should have. Who knows, maybe after reading it you will understand where to go and who to work with.

ORGANIZATION OF PRODUCTION

Everything starts with the organization. You can hire professionals, purchase high-quality materials, install advanced welding equipment. But if the work is organized incorrectly, then all the advantages of qualified personnel and modern technology will not make any sense. So let's start with the organization.

 So, welding can be carried out on two types of objects: it can be a construction and installation or repair facility outside the workshop, or it can be a stand-alone plant. It is believed that working at the factory is more favorable. Employees work in heated and ventilated workshops, they often have more technological equipment at their disposal.

 In the process of work, the same welders can focus their attention on the quality of the resulting seam, on compliance with the welding technology, and so on. Unlike workers who perform repairs on the street, who may be hindered by unfavorable weather, insufficient manufacturability of their equipment and many other factors. However, professional craftsmen are always required at both sites.

 There is also another difference. Often, employees are given individual tasks "on the road" and each of them is responsible for the result himself. At best, they will be assigned a foreman or another manager to monitor the progress of the work. At the factory, everything is much more complicated.

 Firstly, welding within the workshop is more versatile. In the workshop, you can perform welding of any level of complexity, so that when performing particularly responsible work, an appropriate organization is necessary. First-level welders, chief welders, technologists and engineers work. All of them work according to the conveyor type, i.e. one employee performs the part of the work assigned to him and passes it to the next employee (from the welder to the main welder, from the main welder to the technologist, and so on).

 As you understand, with such work, the human factor is inevitable. Also, with a large number of responsible persons, one of them may not perform the work efficiently enough, which will affect the entire production chain. Absolutely any problems can arise here. Starting from the fact that the welders incorrectly selected the welding mode, ending with quality control specialists who could not identify hidden defects and released a defective product to the market.

Also, in addition to the welding itself, a number of other works need to be performed at the production site. For example, to develop a project for the production of welding works and, in general, to compile a detailed package of technical documentation. This requires not only knowledge, but also experience. Such work is entrusted to engineers. They are the ones who draw up drawings and technological maps, select the optimal welding mode and components for performing the work. All documentation is approved, checked by other specialists and only then gets into the hands of the main welder, who already gives instructions to the welders of the first level.

 In the end, the organization of welding production, the development of documentation and other stages should lead to one result — the implementation of a high-quality and durable welded joint. Yes, so many nuances must be observed in order to simply release one product.

 TECHNICAL EQUIPMENT

The basics of welding production do not end with the organization. After all, in addition to employees, there is also equipment at the workplace. The basic kit consists of an inverter, a transformer and a rectifier. Any production, even the smallest, should be equipped with such equipment.

 Such a set of equipment is due to its versatility. With the help of an inverter, even beginners will be able to properly light the arc and form a seam. With the help of a transformer, professional craftsmen will be able to generate any current value. And with the help of a rectifier, you can achieve a better connection.

 If the production is more or less large, then welders will have more technological devices at their disposal. They may have special functions or even perform all the work, practically without requiring the presence of a person. This process is called automation. Let's look at this in more detail.

Mechanization and automation of welding production is a necessary measure if the plant intends to consistently produce a large number of products. Due to technological progress, we have been able to manufacture modern "smart" welding machines that simplify the manual work of the welder. The simplest example of automation is a semi-automatic welding machine that feeds wire into the welding zone using a special mechanism, instead of feeding it manually.

Do not forget that the equipment and technology of welding production are always interrelated. And if the company plans to use modern welding technologies, then the equipment should be appropriate. In recent years, the mechanization of welding production has reached incredible heights. Fully robotic welding machines operating according to a pre-set program are increasingly found in factories. Such robots do not require the presence of a welder at the workplace at all.
