- W2466133057 abstract "目前不锈钢轨道客车车体多采用电阻点焊工艺，但焊点处存在明显的压痕，影响不涂装车体外观质量。部分熔透激光焊技术的研发可以作为解决电阻点焊不锈钢车体弊端的有效手段。为此研发部分熔透型激光搭接焊工艺以期改善车体的表面质量及气密性，并保证接头强度高于电阻点焊接头。进行不锈钢激光焊接工艺试验，考察激光焊接工艺参数(激光功率、焊接速度、离焦量)对接头强度和外观质量的影响规律，从而通过调整激光焊接工艺参数来控制不锈钢激光焊接头质量。 Currently, stainless steel railway vehicles body and structure are usually assembled by resistance spot welding process. The weak points of this process are the poor surface quality and bad airtight due to the pressure of electrodes. The partial penetration lap laser welding is investigated as a solution for the disadvantages of resistant spot welding stainless steel railway vehicles. In this paper the tests of parameters of laser welding including laser power, welding speed and focus distance were performed to get the influence to the strength and appearance quality. Through ad-justing the parameters we can get good quality of laser welding joint." @default.
