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.

摘要翻译： 一种制造负载压缩机涡旋壳体的方法包括以下步骤：锻造加工并随后焊接在一起的近净形状部件。 加工锻造部分以与配合表面一起限定涡旋壳体的特定特征。 顶部和底部之间的界面限定在蜗壳内。 界面处的焊接接头提供蜗壳内的成品表面，使得气流不受不利影响，并且在形成焊接接头之后不需要额外的机器加工。
