Description

Welding and Joining of Advanced High Strength Steels (AHSS): The Automotive Industry discusses the ways advanced high strength steels (AHSS) are key to weight reduction in sectors such as automotive engineering. It includes a discussion on how welding can alter the microstructure in the heat affected zone, producing either excessive hardening or softening, and how these local changes create potential weaknesses that can lead to failure.

This text reviews the range of welding and other joining technologies for AHSS and how they can be best used to maximize the potential of AHSS.

Key Features

  • Reviews the properties and manufacturing techniques of advanced high strength steels (AHSS)
  • Examines welding processes, performance, and fatigue in AHSS
  • Focuses on AHSS welding and joining within the automotive industry

Readership

Professionals requiring information on the welding and joining of advanced high strength steels. Researchers and engineers within the steel and automotive industries will find it informative.
