CruxGNZ Posted March 3, 2004 Share Posted March 3, 2004 I'm going to be mig welding (with gas) some aluminized steel intercooler piping and have a few concerns. Should I grind or sand down the areas to be welded prior to welding? I'm worried about contamination of the weld pool and subsequent hot cracking. Now, I have also heard that unlike galvanized steel, aluminized steel can be sucessfully welded over. Is this true? Any input would be great. !M!

Tim240z Posted March 3, 2004 Share Posted March 3, 2004 Mat, It helps to just buff about 1/2 inch at the weld site of both sections. One thing to be concerned with, it that the pipe is no longer protected by the aluminizing, so it will rust on the inside. Since this will after the air filter, those rust particles will eventually make it's way to your engine. You could send the piping in for coating when you're done to solve that issue.

CruxGNZ Posted March 4, 2004 Author Share Posted March 4, 2004 Thanks Tim . Garrett and Ivan (Chi-town boys) are coming up to my place for me to do some welding for them. I'll have to tell Garrett about the rust issue. !M! Quote Link to comment Share on other sites More sharing options...
Clifton Posted March 6, 2004 Share Posted March 6, 2004 Welds just like regular steel. Galvanized is a little dirtier but still not to bad. I nvere clean either. Quote Link to comment Share on other sites More sharing options...
