激光坯料焊接是指为生产工程坯料而对不同厚度、涂层和/或合金的平板金属进行的对接焊接。为了获得一致且可靠的生产焊缝，需要彻底了解:边缘处理、激光、机器、焊接工程和材料处理。由于这项技术，工程师可以在冲压前将特性设计成毛坯，从而消除加强件，减轻车辆重量，节省资金。由于激光焊接比母材更坚固，具有优异的成形性、腐蚀性和疲劳性能，因此该工艺可应用于许多白车身零件。

LASER BLANK WELDING IS THE BUTT WELDING OF FLAT SHEET METAL OF VARYING THICKNESSES, COATINGS AND/OR ALLOYS FOR THE PURPOSE OF PRODUCING ENGINEERED BLANKS. TO OBTAIN CONSISTENT AND RELIABLE PRODUCTION WELDS A THOROUGH UNDERSTANDING OF: EDGE PREPARATION, LASER, MACHINE, WELDING ENGINEERING AND MATERIAL HANDLING IS REQUIRED. AS A RESULT OF THIS TECHNOLOGY, THE ENGINEER CAN DESIGN PROPERTIES INTO A BLANK PRIOR TO STAMPING, THUS ELIMINATING REINFORCING PARTS, REDUCING VEHICLE WEIGHT AND SAVING MONEY. SINCE THE LASER WELDS ARE STRONGER THAN THE PARENT MATERIAL WITH EXCELLENT FORMABILITY, CORROSION, AND FATIGUE PROPERTIES, THE PROCESS CAN BE APPLIED TO MANY BODY-IN-WHITE PARTS.
