What is seamless welding process?
Regular Bridge-cutoff aluminum alloy doors and windows is made of aluminum, and the connection of aluminum is not specially processed; Regular aluminum clad wood doors and windows is made of wood and aluminum, and the connection of outer aluminum is not processed, with gaps; seamless welding doors and windows introduced seamless welding machine, making the doors and windows revolution into 4 .0 era, the outer aluminum frame adopts seamless welding, after grinding and surface spraying, making the aluminum frame connection seamless, improving the sealing performance and decorative performance of doors and windows.
What is seamless welding?
Seamless welding refers to gas shielded welding or gas shielded-ACR welding for short in electrogas welding. It is a fusion welding that uses arc as heat source and gas as protective medium. In the welding process, the protective gas creates a gas protective layer around the arc, separating the arc and the molten pool from the air, preventing the influence of harmful gases and ensuring the stable combustion of the arc. Gas shielded welding can be classified according to the electrode state, operation mode, shielding gas type, electrical characteristics, polarity, application scope, etc.
What is the working principle of seamless welding?
Different gases can be used for gas shielded welding according to specific conditions. Common shielding gases include carbon dioxide, argon, helium, hydrogen and mixed gases.
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 level is simple; No sculptural feel, more beautiful and more decorative performance; Can make doors and windows better sound insulation, heat insulation effect.
2. The frame is stronger and not easy to deform, extending the service life of doors and windows
We know that the thermal expansion and cold contraction of outer aluminum due to seasonal changes may cause water seepage in doors and windows due to gaps, thus causing corrosion of internal profiles and endangering the service life of doors and windows. If the doors and windows adopt seamless welding process, the above problems are well avoided, the window frame is stronger, and the connection between doors and windows is sprayed more evenly.
