I have two questions about a project i recieved from galvanized shop, first the project is made from square tubing 6X6 HSS, its mainly a frame, every joints i have welded then grinded flush appear to be thicker and i can see the weld line after galvanizing, but before sending it to galvanize those joints was perfectly flush, so why the galvanize seems to be thicker over the weld aeras ? Is it about the HAZ ? Is there a solution to avoid this next time ? A different kind of wire ?Another question, now i have touch up to do on the galvanize, i have two product to so it, i have a rich zinc gallon of a thick product called Galvicon, this product comeIn a paint pot and its really thick, i have to apply it with a brush, then i have to put on it a coat of another rich zinc paint in spray to give a more clean finish, my question is the first production "Galvicon" have to be dilute with something or is it the normal thick texture ? Because even after mixing it with my drill its still really thick!Calculator > Bevel Square
Reply:I've always used these. Heat the base metal up, rub / melt the galvanizing stick on the heated area, wire brush in. Attached ImagesDont pay any attention to meIm just a hobbyist!CarlDynasty 300V350-Pro w/pulseSG Spool gun1937 IdealArc-300PowerArc 200ST3 SA-200sVantage 400

Reply:Was the welded and ground smooth area rougher than the rest of the tubing? |
