Aluminum alloy battery trays are mostly welded via CMT welding. Black oxides formed on weld surfaces need timely removal, especially inside narrow internal corners of T-shaped welds where dead zones inevitably exist with conventional manual grinding. Laser cleaning brings zero damage to base materials and consumes no spare parts, making it standard equipment for battery housing workshops.
02 Pre-Coating Laser Cleaning for Battery Trays
Surface cleaning and roughening treatment are required before applying insulating paint on battery trays. The cleaning process eliminates grease, dust and oxide layers to guarantee a clean substrate; roughening increases surface roughness to strengthen the adhesion and insulation stability of insulating coatings.The integrated laser cleaning roughening process features high efficiency, eco-friendliness and outstanding uniformity, perfectly matching the demands of automated production lines.
