A ship body is covered by a lot of steel plates that are put together by electric welding. I wonder how the enormous strain caused by welding are removed.

    it’s possible to anneal the joints by heating with either MAPP gas or Oxy-Acet heating, but generally the strain is accounted for with the material selection and the design factor.

    It will go beyond its yield point

    the process is called normalizing ,,,pretty easy though …sonaflux the surface to look for cracks .. then when your sure the weld is good (x-ray or whatever) heat the weld and anneal to proper values..Most are air cooled and this reducing the associated stresses and extraordinary moments created…Merry Christmas-Happy New year…from the E
