    dear, please check the jpeg.

    this is a sheet metal fabricated intake manifold. the body is made from a 1.2mm sheet drawing process and the flange is 8 mm thick, which is done by the blanking process. After the sheet metal process has been completed the body and flange will be joined by the MIG welding process. the problem I am facing after welding is leakage from the welding area and also under the flange. there is also some distortion on the flange after welding which is not more than 0.5mm from a different area of the flange. looking for some advice about this process issue. how to maintain the flange flatness after welding or do I need to have a machine cut on the flange face after welding? if yes then which machining process and cutting layout do I have to adopt?

    regards asif

    hy you need a pressure test for weld sealing, and final flatness inspection, then decide based on results

    such sealing normaly require gaskets, and assemble does not include welding

    however, sometimes, there is used welding only for seal, without gaskets, but this is advanced process, that has inspection equipment which goes among each unit of wealding, because a leackeage could be critical

    if possible, search for someone near your area, to advise you directly ... a bit of caution is required with your aproach

    if i may, where does it go ? thus maybe you can compromise it without worry
