Joining
Joining processes are critical to the structural integrity and safety of automotive assemblies. From adhesive bonds and plastic welds to high-strength metal fasteners, every joining method must be rigorously tested to ensure it performs under real-world conditions. Instron offers a comprehensive range of testing solutions to help automotive manufacturers and suppliers characterize the mechanical properties of their joining technologies — from quasi-static testing to high strain rate evaluation.
As lightweighting drives the adoption of new materials in automotive design, adhesive joining technology plays an increasingly critical role. This page covers Instron's testing solutions for automotive adhesive applications — from lap-shear and peel testing to fracture toughness, fatigue, and impact testing to ISO 11343 and other key standards.
Understanding how welded, bolted, and adhesive joints behave under high strain rate conditions is critical to validating crash simulations and developing lighter, stronger vehicle structures. This page covers Instron's high strain rate testing solutions for joined automotive structures, including the VHS system and a wide range of mounting accessories and custom fixtures.
Metallic bolts are used in enormous volumes across automotive manufacturing, from high-strength structural assemblies to lightweight component attachment. This page covers Instron's testing solutions for the full range of bolt testing challenges — including quality control for high-volume production, short bolt testing, nut proof loading, strain measurement, and shear strength testing.
As plastic components become increasingly common in automotive design, ensuring the integrity of plastic weld bonds is critical for both product development and quality control. This page covers Instron's tensile testing solutions for plastic welded joints, including offset gripping options for specimens with non-linear tabs and component test plates for non-standard geometries.
