专家证人兼美国焊接学会讲师特德·V·韦伯（Ted V.Weber）利用他在杜邦公司担任材料故障排除员的漫长经验，简要介绍了基本腐蚀机理。它包括点蚀、晶间腐蚀、应力腐蚀开裂、侵蚀、裂缝和电偶腐蚀，以及选择性浸出。全彩色数码照片显示了焊缝腐蚀造成的昂贵破坏。作者就如何避免和纠正腐蚀提出了明确的建议，包括合金化以提高耐腐蚀性。

Expert witness and AWS lecturer Ted V. Weber draws upon his lengthy experience as a materials troubleshooter for DuPont to present this succinct introduction to basic corrosion mechanisms. It includes pitting, intergranular corrosion, stress corrosion cracking, erosion, crevice and galvanic corrosion, and selective leaching. Fullcolor digital photos illustrate the costly destruction caused by corrosion in welds. The author offers clear advice on how to avoid and correct corrosion, including alloying for resistance.
