Unveiling the Strength Secrets. A weld''s strength can equal or surpass that of the base materials used. Properly executed, it creates a robust and durable joint. Understanding the strength of a weld is critical for industry professionals, from engineers to construction workers, whenever joining two pieces of metal is required.
Dielectric properties and energy storage capability of the Bi-BT nanocomposite were investigated in detail. The Bi-BT nanocomposite showed high polarization, high dielectric breakdown strength (≥1000 kV cm −1 ), postponed polarization saturation, and low remnant polarization with the discharge energy density of ∼10 J cm −3 at 1000 kV cm −1 .

Welding. Welding is a core activity in the fabrication factory, undertaken by skilled, qualified operatives working to a welding quality management system under the control of a Responsible Welding Coordinator. It is used to prepare joints for connection in the shop and on site, and for the attachment of other fixtures and fittings.
Researchers have tried to improve PI energy storage performances by introducing high-ε r polymers such as PSF, 78 LNBR, 79 PVDF, 80 β-CD 81 and Sn-polyester. 82 Regrettably, it comes at the cost of a drop in breakdown strength.
