Practice question

During inspection a seat-frame weld is cracked. Why is field welding of safety-critical seat structures done only per manufacturer procedures?

  1. Improper welds can weaken the seat and void crash performance; manufacturer repair specs preserve FMVSS 222 integrity
  2. Any weld is fine since seats are not safety items
  3. Welds should never be inspected
  4. Cracked welds self-heal under load

Answer: A — Improper welds can weaken the seat and void crash performance; manufacturer repair specs preserve FMVSS 222 integrity
