By mounting the elevator consoles on the elevator shaft walls, the loads imposed by the elevator are transferred to the building's structural support system.
To summarize briefly, the guarantee of the healthy operation of the elevator, to which we entrust our lives, depends on the quality of these consoles.
Disadvantages of welded connection
It is necessary to damage the integrity of the material in order to return from mistakes in the manufacture of the elevator console. There are many variable factors that determine the strength of the welding process against force.
These are mainly:
- Moisture
- Surface cleaning
- Seam evenness (workmanship)
- Electric current adequacy and stability
- Width of the contact surface
- Electrode quality
- Compatibility of molten material and material
- Construction site conditions (height, working area, etc.)
Most welding methods are based on melting and internal stresses and distortions occur as a result of melting. The weld material that solidifies after melting becomes brittle. After brittleness, the material breaks (breaks) with almost no creep after it passes the yield strength.
Not every material is suitable for welding. Some materials may leave the weld after holding it for a while. Welding done by someone unfamiliar with the material can lead to irreversible results. While welding homogeneity cannot be achieved even in welds with weld notches, especially in the manufacture of elevator rail connection consoles, the cut parts are randomly welded without notches.
Changes in material size due to weather and temperature changes may cause cracks and breaks on the weld. In the event of an earthquake, welded joints in elevator consoles, especially in weight sections, will exhibit brittle material behavior against sudden impacts and show sudden rupture.
