Specifications:
AWS A5.7
Description:
Washington Alloy Silicon Bronze is a copper based filler metal containing about 3% silicon and may have small percentages of manganese, tin, and zinc. Silicon bronze is typically used for gas-tungsten arc welding and gas-metal arc welding of copper, brass, bronze, steel, galvanized steels and also cast iron. When working with silicon bronze base metal keep the interpass temperature below 150° F to minimize hot cracking. Base metals of cast iron may need a preheat of 600° F while copper may need a 400-800° F. The use of a small narrow weld puddle will reduce the contraction stresses and give you a faster cooling during the hot-short temperature range.
