ABSTRACT
Weld quality evaluation lies at the center of all aspects of welding. A welding schedule is judged by whether it can produce welds of acceptable quality; a material, before it is used in production, needs to be quali ed as weldable: using standard welding equipment and schedules would yield welds of suf cient size and strength or quality. However, there are no universally accepted standards of weld quality, as re˜ected in an American national standard (Standard Welding Terms and Deˆnitions, ANSI/AWS A3.0:20011), which de nes an acceptable weld as “a weld that meets the applicable requirements.” Therefore, determining a quality weld is largely at the manufacturer’s discretion. This chapter will discuss the common practices for evaluating a weld’s quality.
