| titleOfInvention | Titanium matrix composite welding and postweld heat treatment method |
| abstract | A titanium matrix composite welding and postweld heat treatment method includes the steps: firstly, performing surface pretreatment such as oil removal, pickling, brightening and the like for a titanium matrix composite plate to be welded, and removing oil stains, oxide and attachments of base metal; secondly, butting or lapping treated weldment, welding the titanium matrix composite plate by a CO2 continuous laser welding process, and performing gas shielding for base metal seams by the aid of high-purity argon; thirdly, performing postweld heat treatment for a titanium matrix composite laser welding joint by the aid of a heat treatment system of (950-1100) DEG C/(0.5-2)h+(850-1000) DEG C/(0.5-2)h+(400-500) DEG C/(1-5)h under a vacuum condition; and fourthly, cooling the titanium matrix composite laser welding joint after heat treatment along with a furnace or by using air. The method has the advantages of simplicity, practicability, high strength of the welding joint, less metal heat damage, narrow seam and suitability for large-scale industrial production. |
