I've got a one year old aluminum trailer that has a series of cracks in one area and I think it was just plain bad welding. There are bent square tubes (1" thin wall) that end and were welded to the bed frame (.250 thick approx). The welds have no "waves" to them but look like a big blob going around the tubing. They all cracked right along the welds as well as some right through the center of the welds. Any opinions? I have pictures as well if someone would look at them and give me an answer. The manufacturer wants me to bring it 250 miles to them to repair and if it was just bad welding, I can get it fixed locally and not deal with them. Thanks! Tom
