TAILIEUCHUNG - Standard Symbols for Welding, Brazing and Nondestructive Exmination

As a "language", these symbols are the most precise means for designers and detailers to place welding, brazing, and nondestructive examination information on drawings AND the most mistake-free means for welding personnel to adhere to original plans. | 155Ô D7042bS DSŨHlbl ITS COPYRIGHT 1999 American Welding Society Inc.
