Company name and KD-JW brand
Keju's official introduction names 洛阳科巨激光技术有限公司 and describes the development, manufacture and sale of laser-processing and CNC equipment. The website and the battery brochure carry the 科大金威 / KD-JW LASER brand. Check that the contracting company and the brand on the quoted machine match.
The contact page gives the address as No.6 CNC Industrial Park, Industrial Avenue, Yuetan Town, Yanshi, Luoyang. The English company name shown in this directory is a translation of the Chinese name. Ask Keju for its registered English name, if it has one, and check the names on the contract, invoice and manufacturer documents.
The wider catalogue covers cutting, marking, engraving, cleaning and robots for many industries. Most of those machines are general laser equipment. The battery-related scope below comes from the battery welding page and its brochure.

What these details mean for selection
The brochure describes a continuous fibre-laser welding machine built from a gantry worktable, laser source, control system and water cooling. Keju lists battery copper and aluminium connection pieces, tabs, terminals, busbar connections and shell applications. Ask for welded samples on each joint and cell design you plan to use, especially dissimilar-metal joints.
The parameter table has five power columns, 1500, 2000, 3000, 4000 and 6000 W, while another row gives a shared average output of 2000 W. It also lists a 1080±3 nm wavelength and travel of 1000/800/500 mm on the X, Y and Z axes. Ask Keju which configuration the shared 2000 W row and the other common values apply to. The five power levels are presented on one machine page for that reason.
Keju describes its welds as free of pores, with low deformation and fast sealing; test these points on your own material. A connection weld and a hermetic shell seal need different acceptance methods, and the application list covers welding only, leaving the rest of cell assembly to other equipment.
A 2023 stock-exchange filing names the company
A 2023 response on financial matters concerning Beijing BWT Photonics, published by the Shanghai Stock Exchange, names 洛阳科巨激光技术有限公司 in its customer section. PDF page 29 gives an establishment date of August 2021, registered capital of RMB5.01 million and a business scope covering development, manufacture and sale of laser-processing and CNC equipment.
This is a past third-party filing. It confirms the company's existence and business scope at that time. For current certificates, weld test results or proof of the worldwide delivery coverage Keju advertises, ask the company directly.
Quote the joint, the machine and commissioning together
Send terminal and busbar drawings, alloys, plating, thicknesses, overlap and allowable heat input. Ask Keju to weld representative joints with the quoted source, head and fixture. Agree sectioning, strength, resistance and any leak tests that suit the actual operation. Ask for repeatability and yield figures from those samples, since a photo of a battery fixture gives neither.
Keju's site offers sample work, installation and service support, and its dealer-policy text is general. Put the installation region, operator training, spare parts and support response time in the quotation. Include guarding, extraction, cooling and traceability duties. If you need the welder linked into an automatic PACK line upstream and downstream, ask for that integration as a separate, defined scope.
Buyer questions
Can Keju supply a complete lithium-cell production line?
Its battery material covers a laser welding family for joining applications. It does not describe slurry mixing, electrode coating, winding, filling or formation. Ask about the specific joint process you need, and request documents for any integration Keju quotes beyond welding. Ask full-line suppliers as well, so you can compare scopes.
Is each laser power a separate product?
Keju shows the power options in one family table, with no separate model records and one shared average-output row. Ask for a quote on the exact configuration you need, identified by source power, head and mode.
