Barely, but it can't be recovered after plastic surgery, which is time-consuming and laborious.

This method can be called as follows:

1, the inner cavity should be penetrated and filled with wood blocks, and then the bent aluminum square pipe should be shaped to protect it while straightening, and the wrinkles on the outer surface can be welded and polished. If spraying, it needs scraping pretreatment;

2. If the bend is serious, you can try cutting from the bend, filling the port with plastic, and finally welding, but these will undoubtedly consume more energy and the success rate is not high, and the strength will be discounted. Customers need to consult in advance whether they agree or not.

I hope it helps.
