A company i contract for asked me to repair some brand new aluminum truss, which has fractures in almost every weld. when i was in the event industry, i used miles of this stuff, and it is manufactured by one of the pioneering truss companies, which shall remain nameless. I have seen only one other weld failure from them in the last ten years. The last time, i called them to let them know, and they blamed our crew for mishandling, however the welds were clearly not penetrated. this time, most of the welds are cratered, and the welds have centerline cracks, but from both ends. plates, laces, every joint. this specific truss was not even loaded when it was used. i have cleaned and TIGed it with no problems, however, it bothers me that such a reputable company could be sending this stuff out. if you heard of the justin timberlake accident, you know how this truss is used, often with serveral tons suspended from it. is this all from poor welds?? how many bad sticks are out there??
