Welding Blankets

Pick a blanket large enough to fully cover the area or component you need to protect; common sizes range from small personal shields to large 6x10 ft sheets. For welding and grinding sparks use 7–12 oz/ft² (approximately 0.6–1.0 mm) glass-fiber or silica-based blankets; heavier/thicker blankets offer better durability and heat resistance for prolonged or higher-energy jobs

Look for blankets made of fiberglass, silica, or basalt fibers that list a continuous-use temperature (typically 1000–1800°F / 540–980°C) and an intermittent or spark resistance higher than that. Ensure the material resists molten metal penetration and has appropriate certifications or temperature specs from the manufacturer

Budget welding blankets are commonly available under $50 and can provide adequate short-term protection for light-duty tasks; mid-range and heavy-duty blankets typically cost more and are designed for frequent, high-heat use. Match your purchase to the intensity and frequency of your work rather than price alone

Drape the blanket so it fully covers flammable surfaces with some overlap, and secure edges with clamps, magnetic holders, or metal fasteners rated for high temperatures to prevent movement. Avoid pinning the blanket with combustible materials and keep it free of oil, solvents, and sharp edges that can damage fibers

Keep the blanket clean and dry; brush off slag and metal debris after use, avoid exposure to oils and chemicals, and store it rolled or flat in a dry, cool place away from sunlight. Inspect regularly for burns, holes, or delamination and replace if the protective layer is compromised

Yes, when properly sized and positioned, welding blankets can shield seats, wiring, paint, and plastic components from sparks and heat, but ensure the blanket material is rated for the expected temperature and do not allow direct contact of molten metal with the surface beneath

Check manufacturer specifications for maximum continuous and intermittent temperature ratings and look for standardized safety listings or compliance statements relevant to heat resistance; also verify claims about molten metal and spark resistance rather than relying on general terms like 'fireproof.'
