Layout (template) sector weld removal to drawing

Marking element for the subsequent retraction of cutting and welding is carried out using the patterns (sweeps) imposed on the pipe, on which a chalk line is carried out on the tube cutting (for greater accuracy spray paint). Our proposed Excel spreadsheet allows you to get the dimensions for constructing curves (sweep) for the manufacture of elements with any removal !!! specified characteristics. Enter yellow table cell discharge characteristics and you instantly get the ordinates and abscissas build (24pcs.). Move these points to paronite or cardboard and smoothly connect them together. You got a template to mark the extreme poluzvena challenge. Mirrored the unfolding of extreme poluzvena about a horizontal axis and obtain the well-known "fish." With its help mark out the elements of the average discharge. You can print on a printer.
