Bead Welding(焊珠焊接)是一種通過熔融金屬形成連續珠狀焊縫的焊接工藝,廣泛應用于金屬連接與修複領域。其核心是通過電弧或高溫熱源将焊材與母材熔合,形成均勻的珠狀焊道,确保結構強度和密封性。
工藝原理
Bead welding通過控制焊接電流、電壓和移動速度,使熔池金屬在凝固後形成規則的珠狀結構。這種工藝常見于手工電弧焊(SMAW)和氣體保護焊(GMAW),適用于碳鋼、不鏽鋼等材料的對接與角接(來源:《焊接科學與工程基礎》,機械工業出版社)。
技術分類
質量控制
焊珠的均勻性、無氣孔和裂紋是關鍵指标。需通過目視檢測、X射線或超聲波探傷确保符合ISO 5817等國際标準(來源:國際标準化組織ISO官網)。
工業應用
該技術用于汽車制造、管道工程及壓力容器焊接,尤其在航空航天領域對高精度焊縫要求嚴苛(來源:《現代焊接技術手冊》,中國電力出版社)。
“Bead welding”是焊接領域的專業術語,其含義和用法可綜合以下信息解釋:
