Looking for any "how to" information to weld a bulldozer ripper blade to a mild steel base plate. Company is trying to make a single ripper blade attachment, (3 feet long, 2" thick), to a 325 Cat. The on-site welders tried to weld the blade to the excavator mild steel base plate, 1.25" thick, with four very short mild steel gussets using 7018 rod with a fair amount of build up, no pre or post heat. The base plate was also cut out to insert the ripper to plug weld it from the bottom. After only a few minutes of operation, all the welds from the ripper to the mild steel base plate were broken. Not alot of information out there about doing this but I did successfully weld up a rock crusher roller about 10 years ago that was broken in half. My LWS suggested the Super Missle Weld, not sure of the number. Did a pre and post weld heat and cut the 6" round roller down to get a full pen weld on it and was still in service when they removed it from the job 3 years later. I suggested that they build a heavy duty reciever using 2" ms, 12" tall with 1 gusset forward and aft and 2 gussets on each side to the base plate and bolt the ripper in place. If they want to go without the reciever idea, any ideas what rod to use to weld the gusset directly to the ripper blade? Thanks for any input. Mike
