Welding screen work-zone planner

Perimeter, required screen run and panel count for a rectangular welding zone from entered dimensions, access opening and usable panel width — a quantity estimate, not a screen specification.

Method

M.2026-08-20.1

Three lines of arithmetic on the entered dimensions:

  • perimeter P = 2 × (length + width)
  • screen run R = max(0, P − opening)
  • panels N = R ÷ usable panel width, rounded up

Worked figures: a 4 × 3 m zone gives a 14 m perimeter; a 1 m opening leaves a 13 m run; at 2 m usable width that rounds up to 7 panels. HSE guidance in the source register describes welding curtains and screens as protecting passers-by and nearby workers from arc light — that purpose, not a material specification, is why the count exists.

Limits & stop conditions

T-09
  • Quantity planning only: the count does not assess screen material, certification, stability, overlap between panels, fire performance or your site layout.
  • CAUTION — an opening that equals or exceeds the whole perimeter drives the screen run to zero; the record flags it so the entered dimensions get checked.
  • HOLD — zone dimensions or panel width not greater than 0, or an opening below 0, keeps the record unissued.
