What is the seamless welding process?

Conventional broken bridge aluminum alloy doors and windows are assembled from aluminum, and the aluminum joints have not undergone special treatment; conventional aluminum-clad wood doors and windows are composited of wood and aluminum, and the outer aluminum joints have not been treated, and there are gaps; Seamlessly welded doors and windows introduced seamless welding machines, making the door and window revolution enter the 4.0 era. The outer aluminum frame is welded seamlessly, and then the surface is sprayed after grinding, so that the connection of the aluminum frame is seamless, and the sealing performance and decorative performance of the doors and windows are improved.

Seamless welding machine: Aluminum profile seamless welding machine is a special door and window equipment for 45° angle seam welding, medium T-shaped welding and cross welding. The machine is controlled by Japan's Panasonic system, cylinder pressing, infrared correction, automatic center line, input profile weld length, automatic welding, automatic welding by inputting the welding position on the back of the profile, and at the same time clearing the front weld, saving a processing procedure ( Cylinder compression - lower gun - welding - closing gun, flip the profile - back spot welding - remove the front welding flash). The profile program only needs to be input once, automatically stored, and used at will. Truly tailor-made aluminum alloy, aluminum clad wood seamless welding full set of solutions.

traditional manufacturing process

The traditional door and window manufacturing is actually a process of assembling. No matter what brand, factory or workshop he is, its production process is basically the same. Cut the six-meter-long profile that has been sprayed into the required length, and then perform milling, drilling, and splicing. Such a process flow will inevitably cause surface wear and secondary damage of the profiles. The accuracy of processing cannot be guaranteed fundamentally.

Metal splicing, gaps cannot be avoided;

Followed by air leakage and water leakage, no sound insulation, and other situations cannot be avoided;

Seiko seamless welding process features

1. Beautiful appearance, better thermal insulation and sealing performance

Seamless welding is an upgraded version, using seamless welding technology, the outer aluminum is flat, the layers are simple; there is no bump, it is more beautiful and more decorative; it can make doors and windows better for sound insulation and heat insulation.

2. The frame is more sturdy, not easy to deform, and prolongs the service life of doors and windows

We know that the thermal expansion and contraction of the outer aluminum due to seasonal changes may cause water seepage in the doors and windows due to gaps, thereby corroding the internal profiles and jeopardizing the life of the doors and windows. If the doors and windows adopt the seamless welding process, the above problems are well avoided, the window frame is stronger, and the spraying at the joints of the doors and windows is more uniform.

The upgrading of China's door and window technology is relatively slow. Building doors and windows have become the largest energy consumers in China's buildings, accounting for at least 25% of the total. In order to reduce energy consumption, the country has carried out four energy-saving reforms: Raised to 35%, the second energy-saving reform will increase the building energy efficiency from 35% to 50%, the third energy-saving reform is to increase the building energy efficiency from 50% to 65%, the fourth step energy saving is the basis of the third step energy saving Save another 30%, that is, the so-called 75% building energy saving.

As one of the surface enclosures of buildings, doors and windows directly affect the energy-saving performance of buildings. Improving the thermal insulation performance of doors and windows is the main way to ensure energy consumption of buildings. Nowadays, the use of energy-saving doors and windows for building energy conservation is attracting more and more attention.

The real energy-saving system doors and windows are not a single use of thermal insulation profiles or the use of Low-E insulating glass energy-saving materials. It is a perfect combination of a system. The comprehensive results of the performance of each link are indispensable. To measure whether the building doors and windows are energy-saving or not, it should be the main thing. Three elements are considered, namely convection of heat, conduction of heat, and radiation of heat:

1. The loss of heat is the circulation of hot and cold air through the gap between doors and windows, and the heat is exchanged through gas convection, resulting in heat loss;

2. Heat conduction is the heat transfer by the molecular movement of the material itself used for doors and windows, and it is transferred from one side of the material itself to the other side, resulting in heat loss;

3. Radiation is mainly transmitted directly in the form of rays, resulting in loss of energy consumption.

The seamless welding of broken bridges is an innovation in the door and window industry. It effectively improves the heat loss of doors and windows, and is an important milestone in the development of energy-saving system doors and windows.
