sa akin, mas ok ata palitan ng bago kesa welding.
kaya nasira yan dahil siguro sa kalawang, so may integrity issues na yung pipe. kung di maganda pagkakawelding nyan di maaayos yung problem.
I would also recommend just changing the entire thing. The reason why the pipe broke is corrosion. If it has corroded, then chances are, other parts in the system have also corroded and will break down soon. I would rather just change it and have peace of mind rather than have my vehicle overheat while being stuck in a traffic jam.
