Unverified焊点工艺影响寿命：优选无缝焊接或激光焊后打磨的金属篮，点焊裸露毛刺处最易先锈蚀；用手摸交叉焊点是否平滑可初步判断做工87% similarUnverified焊点质量决定寿命，优质网格架采用满焊或点焊均匀无虚焊，虚焊点在承重后易断裂，可通过检查交叉点焊接是否饱满一致判断86% similarUnverified焊接连接处是生锈重灾区，选一体成型（无焊点）或注塑包边的产品比点焊工艺更耐用；判断方法看架体拐角是否有焊接凸点85% similarUnverified焊接工艺看焊缝是否连续饱满无虚焊，主要承重节点应为满焊而非点焊；喷塑（静电喷涂）表面处理比普通烤漆更耐磨防锈83% similarUnverified焊接节点是金属分层架承重与耐久的关键，散点焊（仅交叉点点焊）比满焊或包边焊易在承重下脱焊松动，选购金属架应看焊点是否密集牢固及是否有加强横梁83% similar
