Abnormal welding repair affects the production cycle, and the short-term welding without repair causes the welding strip and the battery cell to delaminate, which affects the power attenuation or failure of the module;<\/p>\n<p>2. Welding causes damage to the internal electrodes of the battery cell, which directly affects the power attenuation of the component, reduces the life of the component or causes it to be scrapped.<\/p>\n<figure id=\"attachment_7382\" aria-describedby=\"caption-attachment-7382\" style=\"width: 450px\" class=\"wp-caption aligncenter\"><img fetchpriority=\"high\" decoding=\"async\" class=\"wp-image-7382 size-full lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/06\/2023061915495699.jpg\" alt=\"\" width=\"450\" height=\"300\" \/><figcaption id=\"caption-attachment-7382\" class=\"wp-caption-text\"><noscript><img decoding=\"async\" class=\"wp-image-7382 size-full lazyload\" src=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/06\/2023061915495699.jpg\" alt=\"\" width=\"450\" height=\"300\" srcset=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/06\/2023061915495699.jpg 450w, https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/06\/2023061915495699-300x200.jpg 300w\" sizes=\"(max-width: 450px) 100vw, 450px\" \/><\/noscript> <a href=\"https:\/\/www.ray-tron.com\/en\/pvribbon\/\" data-internallinksmanager029f6b8e52c=\"94\" title=\"Photovoltaic welding ribbon supplier_Solar welding ribbon manufacturer_Photovoltaic welding ribbon wholesaler\">Photovoltaic welding ribbon manufacturer<\/a><\/figcaption><\/figure>\n<p>Critical Control Points:<\/p>\n<p>1.
