Carbon-Steel / Titanium Weld

PACE Technologies Etchant Database PACE Technologies Metallographic MET-MANUAL Link

Welding of disimilar metals can be challenging due to the individual properties, including melting temperatures and chemical compositions of the various metals. By analyzing the microstructure and the heat affected zone (HAZ), the quality, strength and properties of the metal interface can be examined.
