TIG Welding (GTAW): Employs a non-consumable tungsten electrode, offering high-quality, precise, and clean welds, ideal for stainless steel and aluminum.
Shielded Metal Arc Welding (SMAW): A versatile manual process, common in heavy construction and maintenance.

HVAC System
Heating (H): Maintains a comfortable temperature in winter, using boilers, heat pumps, or electric resistance.
Ventilation (V): Renews indoor air, removing odors, dust, and bacteria. It can be natural or mechanical (forced renewal).
Air Conditioning (AC): Cools the environment and controls humidity, and may also include heating.
Main Components
A typical system includes:
AHU (Air Handling Unit): Filters, heats/cools, and distributes air.
Air Ducts: Piping for air circulation.
Production Units: Heat pumps, boilers.
Thermostats: Temperature control.
Advantages
Thermal Comfort: Ideal temperature throughout the year.
Health: Improved indoor air quality (IQ), allergies, and mold.
Energy Efficiency: Modern designs focus on reducing energy consumption and operating costs.
Maintenance: Requires regular maintenance (filter replacement) to function correctly.

Structural Assembly
The process generally follows a logical sequence to ensure correct alignment:
1. Foundation and Anchor Preparation: The connection to the concrete base is made using anchors. This is a critical step, as they must be precisely positioned before the concrete cures to allow for a perfect fit of the columns.
2. Superstructure Assembly (Columns and Beams): After the foundation has cured, the columns are lifted and fixed. This is followed by the installation of the main beams, which give shape to the structure and define the building’s layout.
3. Secondary Structure and Bracing: The roof purlins (which will support the roof) and bracing systems, essential for lateral stability against winds, are installe.
