Fusion welding is used at DHPS to repair cylinder heads that are cracked, pitted, or otherwise damaged in such a way that remachining cannot fix them.

Tennessee-based Diesel Engine Parts Corp. (or DHPS, for company’s founding name Diesel Head and Parts Service) has expanded its diesel-engine cylinder head remanufacturing capacity using its refined fusion-welding process, which helps commercial, military, and governmental organizations meet “reuse and recycle” goals. The expansion includes increases in production line machinery and personnel and the addition of key management personnel. The remanufacturing process at DHPS first involves the inspection, disassembly, and cleaning of the cylinder heads (or other types of cast-iron castings). Cylinder heads that are cracked, pitted, or damaged in such a way that remachining cannot fix them are fusion-welded and then stress-relieved, after which they go through the company’s machining process prior to reassembly. DHPS also manufactures replacement blocks and cylinder heads for select diesel engines, and it supports the defense and commercial engine remanufacturing industries with supply-chain solutions.
