Not this

Use this

weld 已含“使接合”义，后接 together 表示“焊在一起”；用 with each other 表示“彼此”与主动作不符，也不自然。
Not this

Use this
Their shared experience welded them together.
在“使紧密结合”义中 weld 是及物动词，必须带宾语（如 them together）；不能像不及物动词那样单独使用。汉语“结合”可不及物，导致漏宾语。

weld 读音像‘沃德’，可联想两片金属在高温下‘沃’地一下熔合，焊成一个牢固的整体（焊接）。
语域：neutral 常见场景：金属加工与制造业、工业技术文档、书面比喻性表达 weld 作动词和名词时通常用于金属加工、制造业或技术文档等具体场景，分别指焊接操作和焊缝；在书面语中也多用于比喻，表示“使紧密结合”。整体属于中性偏正式用语，口语中除非直接谈论焊接，否则不太常用。
与 weld 完美押韵（以 /-ɛld/ 结尾）：held、spelled、swelled、dwelled、welled、shelled。注意拼写相近但读音不同：wield /wiːld/（挥舞）、wild /waɪld/（野生的）、weald /wiːld/（林地）；belt /bɛlt/ 和 melt /mɛlt/ 以 /-ɛlt/ 结尾，也不押韵。
