1. Electrical Pre-Heating Electrical Pre-Heating is used to gradually raise the temperature of materials before welding or processing to reduce thermal shock and prevent cracking.

2. Electrical Post-Weld Heat Treatment (PWHT) Electrical Post-Weld Heat Treatment (PWHT) is a controlled process applied after welding to relieve residual stresses, improve material toughness, and restore ductility.

3. Annealing Annealing is a heat treatment that softens metal, improves ductility, and relieves internal stresses, making it easier to work with and shape.

4. Gas Combustion Gas Combustion is a method using controlled gas burners to heat components uniformly, commonly used for drying or preheating applications in the field.

5. Normalizing Normalizing this involves heating steel to a specific temperature and then air-cooling it to refine the grain structure and improve mechanical properties.

6. Refractory Dry Out Refractory Dry Out is critical process for safely removing moisture from refractory linings in furnaces and kilns before commissioning, ensuring structural integrity.

7. Tempering Tempering is conducted after hardening, tempering reduces brittleness and enhances toughness and strength in metals.

8. Temporary Furnace Temporary Furnace is custom-built, mobile heat treatment enclosures that provide flexibility for on-site treatment of components that cannot be moved.
