Each welding specialist should have a workplace called a welding post. Its organization depends on the type of work, the dimensions of the parts and structures that the welder makes. Today we will consider options for arranging the welder's workplace, talk about the necessary equipment and requirements!
Types of Posts
First, let's answer the question - what is a welding post? This is the name of the workplace, which is equipped with a full set of equipment connected technologically among themselves. Depending on the type of work, posts can be mobile and stationary. Consider each view in more detail!
Stationary post
As a rule, the equipment of a welding station includes the following elements:
- current source;
- set of necessary equipment for work;
- table for various devices, for example, electrodes;
- chair for the specialist;
- toolbox;
- electric holder;
- circuit breaker.
Another important component is ventilation devices. Usually these are exhaust umbrellas or special fans. The fact is that during welding, gases are released that can poison the welder. To prevent this, it is necessary to remove gases from the room. The ventilation of the welding station should be sufficiently powerful and ensure an air exchange of at least 40 m 2 / h. If this value turns out to be even slightly less, volatile waste will accumulate at the welder's workplace, affecting the respiratory organs of a specialist. By the way, modern exhaust equipment is often equipped with dampers that allow you to adjust the intensity of removal of harmful gases from the workplace.
Another innovation of the ventilation system is a flexible sleeve, which allows you to locate ventilation directly in the work place. The main advantage of the sleeve is the possibility of continuous welding in rooms that are not ventilated.
Cabin
Absolutely all elements of the welding station should be located in the cab. There are also certain requirements for it. For example, the size of this cabin is clearly set - 2000 × 2500 × 2000 mm. The top of the cab is open. Walls are usually made of the following materials:
- tarpaulin;
- plywood;
- thin steel.
Please note: tarpaulin and plywood are pre-treated with flame retardants. Another feature is that the walls of the cab are usually painted in light gray, which absorbs ultraviolet light.
Requirements for welding posts apply to the floor - it must certainly be fire resistant. And the norm of lighting in the cockpit is at least 80 Lux. A switch and a magnetic starter are installed at each post - they turn the current on and off.
Desktop
Another important element is the welding table. The simplest models are made of a metal frame, which is sheathed with sheet steel. If you need a table that can withstand heavy weight and is not exposed to a welding beam, you should pay attention to the cast iron model. Spatter of hot metal does not stick to it. For welding stainless steel, a table made of an alloy of copper and aluminum is suitable. This composition is good in that it does not leave scratches on the surface of the products.
Mobile post
A mobile welding station is simply necessary for welding large items. Usually it is located in an open area, and therefore it is equipped with a canopy that will protect the welder from light radiation and precipitation. The welder’s mobile workplace is equipped with special cabinets - they usually store all the necessary devices - electrodes, various tools.
During the execution of any welding work, the so-called welding aerosol (harmful gases and substances) is released. This aerosol is extremely harmful to the worker. It is worth noting that when working at mobile posts, such a mixture quickly dissipates, so the post does not need to be equipped with ventilation. In order for fresh air to enter the workplace, all the walls of the mobile post have a gap of half a meter.
The welder’s mobile position also needs good lighting, usually the lamp is located directly above or near the table top. A sufficient amount of light can not only reduce the load on the welder's organs of vision, but also provides the conditions for the implementation of labor-intensive products. In addition, grounding is necessary - it will prevent electric shock to the worker.
Equipment for different types of work
The equipment of the welding station depends on the types of welding. As you know, there are different types of it - arc, manual, electric arc, in the environment of shielding gases and others. Therefore, the necessary equipment for fasting is different. For example, a welding station for arc welding necessarily includes an apparatus for work, wires (they are needed for welding), a power source, electrode holders and mechanisms for starting.
When working with an electric torch, the welder will need:
- compressor;
- rheostat;
- burner;
- current source.
Three-phase arc welding is not possible without electromagnetic contactors. When welding with alternating current, a transformer is required (it must be with a high open-circuit voltage) and an oscillator, which will stabilize the arc burning.
For all types of welding, a table, grounding and protective equipment are required. Another requirement is the safety of work.
