Glass panes on a mild steel window frame. Three welds shut the window permanently. How do we open them now?

When they installed the airconditioning on our floor, they welded the windows shut to prevent people from opening the windows. Now that it is pleasant outside, we would like to open them again. There is a mild steel frame to which the windows are attached with a hinge. The window frame is also made of steel and they are shut and welded at three points each. How do we open them without breaking the glass or damaging anything else? What is the easiest way? and what is cheapest solution? – Thanks and if your solution works about a hundred people will be very happy!

    Remove panes adjacent to welds…Use cutting torch to cut thru welds…when window opens, re-install panes..

    Welds are often removed using chippers but that would likely damage the frame or break the glass if it can not be removed. Using a hand-operated grinder (and eye protection) may remove the welds slowly and carefully. If the welds are not large even a small Dremel may work. Of course be sure none of the welds help hold the air conditioner in place for your particular set up. Good luck.

    Dremel tool with a reinforced cut off wheel. Makes a hair line cut.

    If you go to a community college or trade school where they teach welding and ask them, they would know and might come over to fix the window for free.

    Since chiseling would probably break the glass, I would suggest getting a cutting wheel, that could mount on a drill or something like that.
