trickedcarbine Posted March 19, 2015 Report Share Posted March 19, 2015 im going to convert to a soda blaster. read some bad stuff on glass bead. i think its one of the reasons i have had such a hard time with welding after glass bead blasting..Turns out that brown slag has been molten glass! Not junk in the aluminum.... Pita! Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted March 19, 2015 Report Share Posted March 19, 2015 It depends on glass , some imbed inpurities in the aluminum, I get my glass from a machine shop that uses it before they weld n repair valve pockets on aluminum heads. I have never had a problem welding on it but have had issues with other media like black beauty mixed with the glass, I also boil them out before welding works mint Quote Link to comment Share on other sites More sharing options...
