Welding Inspection & Metallurgy API ICP Self Study Notes

Weldability is related to many factors including the following: 可 焊 性 的 因 素 有 :
a. The metallurgical compatibility of the metal or alloy being welded, which is
related to the chemical composition and microstructure of the metal or
alloy, and the weld filler metal used. 金 属 或 合 金 焊 接 冶 金 的 兼 容 性 .
b. The specific welding processes being used to join the metal. 具 体 所 用 的 焊
接 方 法 .
c. The mechanical properties of the metal, such as strength, ductility and
toughness. 金 属 的 力 学 性 能 .
d. The ability of the metal to be welded such that the completed weld has
sound mechanical properties. 已 完 成 的 焊 缝 具 有 良 好 的 力 学 性 能 .
e. Weld joint design. 焊 接 接 头 设 计 .
