Understanding the difference between bonding and welding

Bonding and welding are two crucial processes for the effective joining of composite structures without the need for fasteners, though they are not interchangeable. Bonding requires an adhesive or bonding agent to “attach” parts and structures made of similar or dissimilar materials together, creating a strong, structural connection. Alternately, welding joins two composite parts together through the use of heat and/or force, resulting in the “disappearance of joint surfaces … and creating a unitized structure.”
