    requirement:
    1. The weld bead is required to be smooth during welding, and
    there shall be no welding defects such as slag inclusions, and defects shall be
    repaired in time. The weld height is generally close to that of the steel plate.
    When intermittent welding is used, the weld length and spacing should be
    uniform.
    2. When the production parts require sealing and continuous welding,
    the phenomenon of stomatal trachoma shall not occur at the weld.
    3. The
    welding height is required to be not less than the thickness of the base metal
    (weld parts) during welding. When the base material (weld parts) of different
    thicknesses are welded, the weld height shall not be less than the thickness of
    the thinnest base metal (weld parts).
    Welding is achieved by the following
    three ways:
    1. Fusion welding - heating the workpiece to be joined to
    partially melt it to form a molten pool. After the molten pool is cooled and
    solidified, it is joined. If necessary, it can be added to the filler. It is
    suitable for welding of various metals and alloys. pressure.
    2, pressure
    welding - welding process must apply pressure to the weldment, belonging to the
    processing of various metal materials and some metal materials.
    3. Brazing -
    A metal material with a lower melting point than the base material is used as
    the brazing material, and the base material is wetted by the liquid brazing
    material, the joint gap is filled, and the parent metal material is mutually
    diffused to realize the link weldment. Suitable for welding of various
    materials, also suitable for welding of different metals or different
    materials.
