Respuesta a "Can superglue be used instead of soldering, and would it be safe?"TLDR: No. Read below comment by me. You’re looking for epoxy, clamps, metal to metal, on clean, possibly slightly rough surface. I did that for a customer once and told her to just leave the lid open. She didn’t listen, but it held for six months so she was happy and it saved her $500. Stop. Listen. Research. Plan. Execute.
