Abstract: This arc spot welding method for dissimilar materials joins a steel upper plate and a non-ferrous metal lower plate. The upper plate has a flat plate-like base part and an upright wall part erected on the base part. The base part has a through-hole. The arc spot welding method for dissimilar materials includes superposing the base part on the lower plate so that the lower plate faces the base part via the through-hole; and arc-welding the base part and the lower plate by filling the through-hole with a molten weld metal at a position, which is a target position, offset in the direction opposite the upright wall part from the center of the through-hole.

Abstract: A liquid separation constituent is used by covering a first element portion having a fiber layer for separating liquid from gas discharged from a compressor, and includes a second element portion, a holding portion, and a non-element portion. The second element portion is a tubular portion having a fiber layer that is disposed on the outer side in the radial direction so as to surround the first element portion when the second element portion covers the first element portion and further separates liquid from gas separated by the first element portion. The holding portion is a portion that holds the second element portion such that a gap is formed between the first element portion and the second element portion in the radial direction. The non-element portion is a portion configured to suppress liquid seeping out from a lower portion of the first element portion from scattering to the second element portion.
