Welding Question
I'm fabbing some new railing sections for our deck, getting rid of all of the wood but using my existing spindles that were 1/2" rigid conduit which is galvanized. They are getting welded between a pair of 1/2x1.5" C channels, top spindle inside the C, bottom atop the C (open sides of the channels face down so they don't collect rain). My question is welding the galvanized pipes. I'm running them across the belt sander about 1/2" up on each end to clean metal, but the galvanizing is inside, too. I know the heat from welding creates a weak cyanide gas in the fumes. Am I OK just keeping a fan pushing all the fumes away from me or do I need to take other precautions? Never welded on galvanized metal before....Roger
