Weldable Primer

admin

I've been having a problem with some material from the mill with red "weld able" primer on it.  I'm running .045 dual shields at various temps and speeds but I am still getting pinholes left and right.  The only way I can get away from that is to prep the areas needed to be welded and with it tacked down already, it's still not 100%.  Any help with this would be great.-Mike
Reply:i never like to weld over mill finishes, i always take a grinder with a sanding disk and expose fresh metal first, seems to help me out
Reply:I've never had very good luck MIG welding through these "weldable primers". I think stick welding is what they refer to when they say "weld able". I always grind off the stuff.
Reply:Bad thing is that stick welding isn't good for production.Common sense in an uncommon degree is what the world calls wisdom.
