1. , for a method for the section components of welding plastic material, especially PVC, comprise the following steps:

  • -preparation at least two section components (3;

    3a, 3b;

    60,61), described at least two section components (3;

    3a, 3b;

    60,61) be arranged to respective want soldered region (4;

    62,63) facing with each other;

    -corresponding to described section components (3;

    3a, 3b;

    60,61) at least one wants soldered region (4;

    62,63) generate groove (19), the step generating described groove (19) is by means of at least one section components (3;

    3a, 3b;

    60,61) the removal operation on neighboring performs;

    -heating is described wants soldered region (4;

    62,63);

    -want soldered region (4 by described;

    62,63) mutually couple, by described section components (3;

    3a, 3b;

    60,61) be mutually pressed against to make describedly to want soldered region (4;

    62,63) contact with each other;

    -want soldered region (4 by described;

    62,63) step coupled comprises wants soldered region (4 by described;

    62,63) mutual melting is to limit the sub-step of weld seam and to generate the sub-step in the accommodation lattice district (19a) limited by described at least one groove (19);

    Described weld seam is created on the inside of described accommodation lattice district (19a);

    It is characterized in that, described by described want soldered region (4;

    62,63) step coupled comprise corresponding to described accommodation lattice district (19a) arrange hold casting die (27), with the step stoping described weld seam to leave described accommodation lattice district itself.
