Bead Welding(焊珠焊接)是一种通过熔融金属形成连续珠状焊缝的焊接工艺,广泛应用于金属连接与修复领域。其核心是通过电弧或高温热源将焊材与母材熔合,形成均匀的珠状焊道,确保结构强度和密封性。
工艺原理
Bead welding通过控制焊接电流、电压和移动速度,使熔池金属在凝固后形成规则的珠状结构。这种工艺常见于手工电弧焊(SMAW)和气体保护焊(GMAW),适用于碳钢、不锈钢等材料的对接与角接(来源:《焊接科学与工程基础》,机械工业出版社)。
技术分类
质量控制
焊珠的均匀性、无气孔和裂纹是关键指标。需通过目视检测、X射线或超声波探伤确保符合ISO 5817等国际标准(来源:国际标准化组织ISO官网)。
工业应用
该技术用于汽车制造、管道工程及压力容器焊接,尤其在航空航天领域对高精度焊缝要求严苛(来源:《现代焊接技术手册》,中国电力出版社)。
“Bead welding”是焊接领域的专业术语,其含义和用法可综合以下信息解释:
