The ABC's of Nondestructive Weld Examination Reprinted courtesy of Welding Journal magazine An understanding of the benefits and drawbacks of each form of nondestructive examination can help you choose the best method for your application. The philosophy that often guides the fabrication of welded assemblies and structures is "to assure weld quality. The application determines what is good or bad. Generally, any weld is of good quality if it meets appearance requirements and will continue indefinitely to do the job for which it is intended. The first step in assuring weld quality is to determine the degree required by the application. A standard should be established based on the service requirements.

I know you'll know the answer Thanks for being there That could mean any rod that melts lower than the base metal. Silicon bronze is also called sil-bro.

Development[ edit ] After the discovery of the short pulsed electric arc in by Humphry Davy   and of the continuous electric arc in by Vasily Petrov ,   arc welding developed slowly. Coffin had the idea of welding in an inert gas atmosphere in , but even in the early 20th century, welding non-ferrous materials such as aluminum and magnesium remained difficult because these metals react rapidly with the air and result in porous, dross -filled welds. To solve the problem, bottled inert gases were used in the beginning of the s. A few years later, a direct current , gas-shielded welding process emerged in the aircraft industry for welding magnesium.
