Project Introduction: Refrigerator Compressor Housing Projection Welder

Sep 16,2026

The refrigerator compressor housing is a core pressure‑bearing and sealing structure of refrigeration equipment. Conventional segmented welding features scattered heat input and unstable pressure application, which easily causes housing deformation, deep weld‑spot indentations, cold joints, surface oxidation‑blackening and further leads to poor assembly, abnormal operating noise and unstable sealing performance.

The Haifei refrigerator compressor housing projection welder is specially developed for dedicated projection‑welding working conditions of refrigerator compressor housings. It delivers firm weld spots and low housing deformation.

I Customer Background and Pain Points

One customer focuses on core refrigeration structural parts such as refrigerator compressor housings, supporting feet and connecting supports. Its products are widely adapted for refrigerators, freezers and cold‑chain refrigeration equipment.

Production pain points of the original welding process:

1.Uneven heat input in segmented welding readily causes warping, indentation and roundness deviation of housings.

2.Large fluctuation of welding pressure and energy output leads to insufficient projection‑point fusion‑pressing, easily generating cold joints and undersized nuggets.

3.Inconsistent positioning references from repeated manual clamping bring deviations in weld‑spot positions and indentation depth.

II Customer Requirements

1.Adapt to housing projection‑welding operations, stabilize weld‑spot fusion effect, improve welding strength and reduce defects such as cold joints and loosening.

2.Optimize welding heat input and pressure‑application control, mitigate housing deformation, indentations and oxidation‑blackening.

3.Unify welding forming standards, stabilize weld‑spot strength and sealing performance, guarantee air‑tight effect and operating stability of compressors.

III Custom‑Developed Solutions

Targeting customer requirements, the dedicated R&D team repeatedly tuned and optimized schemes in view of welding difficulties of refrigerator compressor housings, to ensure deliverables fit customer demands. Details are as follows:

1.Process verification: Conduct multiple groups of exclusive projection‑welding process tests for refrigerator compressor housing structures of different plate thicknesses and dimensions.

2.Equipment selection: Adopt Haifei refrigerator compressor housing projection welder. It effectively mitigates thin‑wall housing deformation and surface blackening, with regular weld‑spot forming and stable strength.

3.Structural design: The welding pressure‑applying mechanism of the equipment runs smoothly with precise positioning. Custom‑built exclusive tooling for refrigerator compressor housings reduces positioning offset.

4.Core Advantages

Efficient & stable: stable operation, high productivity.

Good welding effect: uniform weld spots, reliable sealing.

Fine forming: stable performance, low deformation.

IV Delivery, After‑Sales Service and Customer Feedback

Pre‑acceptance and equipment inspection were carried out. Continuous trial operation maintains stable welding pass rate. After commissioning, all original welding‑related production pain points of the customer are fully resolved. Timely, professional and thoughtful after‑sales service earns positive customer comments.
