Default Re: Welding newbie need advice

You can also try sleveing the thiner tube with a chunk of pipe , are these dismillar metals ? If you have a grinder see what the grind spark looks like . High carbon (black) steel pipe is never going to bond to cromeoly steel very well . You may have better luck brazing then mig.
Spotting works to keep temp down ,but creates areas of slag inclusion that weakens joint strength. Like anything else everybody has there opnion and tech. That work for what they want to do . Good luck.
we few, we happy few, we band of brothers.
