AI computing clusters have entered the era of 100kW power density per rack, new energy vehicles are rapidly shifting to 800V high-voltage fast charging, and sectors such as 5G base stations and energy storage systems continue to demand higher thermal performance. Liquid cooling has evolved from an optional solution into a critical safeguard for the stable operation of high-power devices.<\/p>\n<p style=\"text-align: justify\">At the heart of liquid cooling technology is the cooling plate &mdash; and in its volume manufacturing process, welding is one of the most critical steps.<\/p>\n<p style=\"text-align: justify\">Welding Challenges for Liquid Cooling Plates<\/p>\n<p style=\"text-align: justify\">To meet rising heat dissipation demands, the core material of cooling plates is gradually transitioning from aluminum to copper. Copper offers a thermal conductivity of up to 400 W\/m&middot;K &mdash; nearly double that of aluminum &mdash; enabling far more efficient heat transfer and delivering a strong advantage in high-performance liquid cooling applications.<\/p>\n<p style=\"text-align: justify\">However, copper welding is notoriously one of the toughest challenges in laser processing. When using conventional near-infrared lasers (such as 1080nm fiber lasers) on copper, three major problems arise:<\/p>\n<ul style=\"text-align: justify\">\n<li>Low absorption rate: Copper absorbs less than 5% of near-infrared light. Laser energy cannot be effectively absorbed by the material, resulting in extremely low welding efficiency.<\/li>\n<li>Uncontrollable spatter: As copper transitions from solid to liquid, its absorption of infrared light spikes abruptly. The weld pool rapidly heats up and boils, causing severe spatter.<\/li>\n<li>Poor sealing: Pores easily form in the weld seam. Since cooling plates must withstand coolant pressure over long periods, these pores increase the risk of leakage.<\/li>\n<\/ul>\n<p style=\"text-align: justify\">Domestic <a rel=\"nofollow noopener\" class=\"anchor_47ae9ec4c0978a1293d1030e30034b8a\" title=\"Laser Welding\" href=\"https:\/\/www.hanstcs-laser.com\/laser-welding\/\" target=\"_blank\">Laser Welding<\/a> manufacturers have tried various approaches &mdash; increasing laser power, using oscillating welding heads, adding filler wire, employing ring-spot beams &mdash; and while results have improved to some extent, none have addressed the root cause.<\/p>\n<p style=\"text-align: justify\">Red-Blue Laser Composite Welding: A Comprehensive Upgrade in Welding Performance<\/p>\n<p style=\"text-align: justify\">Copper absorbs blue laser light at a rate of over 50% &mdash; more than ten times that of infrared lasers. With efficient energy absorption, the welding process becomes far more controllable.<\/p>\n<p style=\"text-align: justify\">During material heating, the absorption rate changes more gradually, keeping the weld pool stable from start to finish. A stable temperature field allows gases to escape smoothly, virtually eliminating porosity. Spatter is nearly eliminated, producing continuous, dense, and smooth weld seams.<\/p>\n<p style=\"text-align: justify\">Due to the limited beam quality of semiconductor blue lasers &mdash; which lack deep penetration capability &mdash; practitioners have developed a method that combines infrared fiber lasers with semiconductor blue lasers, known as IR-blue laser hybrid welding. This approach harnesses both the deep penetration of infrared light and the high absorption rate of blue light. The dual-beam synergistic welding achieves high efficiency, low spatter, and superior quality &mdash; meeting the demands of precision processing for highly reflective materials.<\/p>\n<p style=\"text-align: justify\">Power Layering for Precise Matching<\/p>\n<p style=\"text-align: justify\">Today&rsquo;s industrial-grade <a rel=\"nofollow noopener\" class=\"anchor_47ae9ec4c0978a1293d1030e30034b8a\" title=\"Blue Semiconductor Laser\" href=\"https:\/\/www.hanstcs-laser.com\/blue-semiconductor-laser\/\" target=\"_blank\">Blue Semiconductor Laser<\/a>s have formed a complete product matrix ranging from hundred-watt to kilowatt class, flexibly adaptable to the welding requirements of different cooling plates.<\/p>\n<p style=\"text-align: justify\">Han&rsquo;s TianCheng Semiconductor Co., Ltd. has developed multiple mature IR-blue laser hybrid welding power configurations. Common setups include: 500W blue + 2000W IR fiber laser, 1000W blue + 2000W IR fiber laser, and 2000W blue + 2000W IR fiber laser. Users can flexibly select configurations based on copper thickness, weld seam structure, and production efficiency requirements.<\/p>\n<p style=\"text-align: justify\"><img decoding=\"async\" src=\"https:\/\/ecdn6.globalso.com\/upload\/p\/3491\/image_other\/2026-08\/14-1.png\" alt=\"14.png\" \/><\/p>\n<p style=\"text-align: justify\">Typical Application Scenarios<\/p>\n<p style=\"text-align: justify\">AI Computing Cooling Plates: Seal welding of copper-based cooling plates, producing smooth, defect-free weld seams with airtightness that meets stringent industry standards.<\/p>\n<p style=\"text-align: justify\">Dissimilar Metal Joining: Welding between copper base plates and stainless steel water inlet\/outlet fittings on cooling plates. The blue laser outer ring preheats while the infrared inner ring provides deep penetration, with independently adjustable power &mdash; completing reliable dissimilar material welding in a single pass.<\/p>\n<p style=\"text-align: justify\">Blue Lasers: A New Choice for Liquid Cooling Manufacturing<\/p>\n<p style=\"text-align: justify\">IR-blue hybrid welding has transformed the traditional copper welding process, making it more stable, efficient, and reliable. As the airtightness standard for cooling plates is anchored to &ldquo;zero defects,&rdquo; IR-blue hybrid welding has evolved from an optional process into a decisive competitive force.<\/p>\n<p style=\"text-align: justify\">Liquid cooling is in a phase of rapid development.
