摘要： A method of fabricating a load compressor scroll housing includes the steps of forging near net shape parts that are machined and subsequently welded together. The forged portions are machined to define specific features of the scroll housing along with the mating surfaces. An interface between top and bottom portions is defined within the volute chamber. The weld joint at the interface provides a finished surface within the volute chamber such that airflow is not adversely affected and additional machine process are not required within the volute chamber after formation of the weld joint.
