I'm getting ready to fab up my new front bumper and winch support box. However my design involves adding on some length to the front frame horns to clear the winch. To do this I plan on welding some steel channel to the ends of the frame horns and then welding in some 4x6x1/4 tube steel between the frame rails to support the winch. My question is this...I've heard that welding onto the frame is bad and not to do it. If I remember correctly what was stated was that it would weaken the frame and/or the welds wouldn't hold due to frame flex. Is this true or just an unfounded rumor. Please advise. All welds would be done using a lincoln arc welder and if need be I could preheat the frame rails to accept the welds and reduce the chances of differential temperature warping.Thanks for the help...
