billyO Posted October 26, 2014 Share Posted October 26, 2014 Hello all. I hope that the fall weather is treating y'all better than me. My question for those with more experience: About 2 weeks ago I prepared a 12" long billet of 11 layers of alternating 15N20 and 1095, welded a handle on and put 3 wire wraps around it, Unfortunately, before welding it, I realized I didn't have enough propane, and then fall happened here in the foothills of Mt Rainier and I haven't been able to work in the shop since then. Do I need to worry about any rust affecting the first weld seeing as it's been sitting in my shop for a couple of weeks or should I just go ahead and heat, flux and weld as normal? Thank you in advance. Quote Link to comment Share on other sites More sharing options...
jmccustomknives Posted October 26, 2014 Share Posted October 26, 2014 No, once I left a billet laying on the floor forgotten for well over a year. Lets just say, steel and the Alabama climate aren't good friends. Just heat, flux and start where you left off. Quote Link to comment Share on other sites More sharing options...

ThomasPowers Posted October 27, 2014 Share Posted October 27, 2014 a flux that is more active than quartz sand or powdered glass is designed to remove metal oxides guess what rust is? I prefer clean metal as every bit helps; but I have welded a number of "messy items" before. I do tend to be more generous on the flux however... (climate we are sweltering down here with 67 degF and *58%* relative humidity; actually hotter at my house 200 miles north, 70 degF but only 38% RH---still awfully high compared to the single digit humidities we often have there...)

basher Posted October 27, 2014 Share Posted October 27, 2014 spray it with wd40 wont affect the weld , helps prevent initial oxidising and will keep some rust off Quote Link to comment Share on other sites More sharing options...
