Soldering Spout & Handle to Raised Body
壶嘴与把手的接焊起凸件

起凸成型的壶身需装配嘴、把。先在接合面涂硼砂焊剂，定位后以银焊料（如 BAg-7）配氧乙炔或微型焊枪加热至焊料流布。焊后酸洗去除焊渣与氧化，再打磨抛光。注意加热均匀，避免壶身已退火软区再次过热塌陷。
A raised body needs spout and handle fitted. Coat the joint with borax flux, position it, then heat with silver solder (e.g. BAg-7) using oxy-acetylene or a mini-torch until the filler flows. Pickle after to remove flux and scale, then grind and polish. Heat evenly so the already-softened body doesn't collapse from overheating. ---
