Glenn Posted December 16, 2009 Share Posted December 16, 2009 Anyone else notice that high ambient humidity effects forge welding? Anyone know the reason why? Quote Link to comment Share on other sites More sharing options...
pkrankow Posted December 16, 2009 Share Posted December 16, 2009 I haven't noticed humidity affecting my attempts, but humidity would add extra mass to heat, and displace O2 at the same time. This means that you now have more air to heat, with less oxygen to consume in a given volume. Phil Quote Link to comment Share on other sites More sharing options...
GobblerForge Posted December 16, 2009 Share Posted December 16, 2009 I have noted over the years that forging on rainy days, when the humidity is in the 90's, that I have more difficulty getting the fire as hot. I attribute this to there being more water in the fire, thus cooling. On dry days it's a little easier to forge and work the fire. On a related note, my shoulders hurt more when I work on a rainy days as well. Gobbler Quote Link to comment Share on other sites More sharing options...
Francis Trez Cole Posted December 16, 2009 Share Posted December 16, 2009 here in florida you can't put enough flux on the joint I have to spoon it on that helps a lot. we average 80 to 90% almost all the time. Quote Link to comment Share on other sites More sharing options...
dablacksmith Posted December 16, 2009 Share Posted December 16, 2009 well i havnt noticed the difference till you came up with this thread but.... when i moved from the seattle area (high humidity) to arizona (no humidity) i have found it easyier to weld ... I was thinking it was just finally getting better but.. Quote Link to comment Share on other sites More sharing options...
Rob Browne Posted December 16, 2009 Share Posted December 16, 2009 If atmospheric conditions make any difference it would have to be affecting the fire surely. Once the metal is heated past water boiling temperature the water would become insignificant as it would just vapourise off and to start with there is not much. As for the fire rainy weather could make a difference but remember, we often wet our coal before using it anyway. As for gassers it could change the air fuel mix a bit and for getting the temperatures necessary for welding this could be critical if your burner is only just big enough to start with. I wonder if during hot, humid weather we are just a bit too quick to get away from the heat and just pull the job out a second or two earlier than we normally would as its not very comfy near a hot forge any time let alone with high humidity. Now balance these ideas with all the electrons used in their creation :) Quote Link to comment Share on other sites More sharing options...
