Interview Questions for Glass Automotive Glazing

Windshield replacement is a precise process requiring specialized tools and expertise. It begins with safely removing the old windshield. This involves carefully cutting the urethane bond holding the glass in place using a specialized wire. Then, the old windshield is removed, and the area is thoroughly cleaned. Any remaining old adhesive must be removed to ensure a proper bond for the new glass. The new windshield is then carefully positioned and secured using fresh urethane, applied in a precise bead around the perimeter of the glass. The glass is then firmly held in place while the urethane cures. Finally, the process involves inspecting for proper adhesion and sealing.

Think of it like building with LEGOs: you need to carefully take apart the old structure before putting the new one together, ensuring a perfect fit and strong bond. Each step is crucial for a safe and leak-free result.

Automotive glass comes in various types, each with specific properties. Laminated glass is the most common type used for windshields. It consists of two layers of glass bonded together with a layer of polyvinyl butyral (PVB) interlayer. This interlayer adds significant strength and safety, holding the glass together even if it shatters. Tempered glass, also called toughened glass, is typically used for side and rear windows. It’s heat-treated to increase its strength. When it breaks, it shatters into small, relatively harmless pieces, unlike laminated glass which tends to stay together. There are also specialized glasses, such as acoustic glass, designed to reduce noise, and heated glass for defrosting.

• Laminated Glass: Windshields; Strong, shatter-resistant.
• Tempered Glass: Side and rear windows; Breaks into small, blunt pieces.
• Acoustic Glass: Reduces road noise.
• Heated Glass: Defogging and defrosting.

A chipped windshield can be repaired if the damage is relatively small and doesn’t affect the driver’s line of sight. The repair involves injecting a resin into the chip to fill the void and restore the structural integrity of the glass. This process involves cleaning the chip, injecting the resin, and then curing it using ultraviolet (UV) light. The resin matches the refractive index of the glass, making the repair almost invisible. However, larger cracks or chips that spiderweb or affect the structural integrity of the glass usually require a full windshield replacement for safety reasons.

Think of it like filling a small hole in a wall with putty – it repairs the damage, but a large crack would require more substantial repair or replacement.
