Weld Spacing: Minimum Distance Between Welds According to
This tutorial will guide you through standard-based minimum weld spacing requirements and provide general rules applicable in piping, pressure vessels, and tank structures.

This technical article provides a comprehensive review of minimum weld spacing requirements according to major international codes and standards. The analysis covers ASME, API, AWS, ISO, and EN standards with specific focus on pressure equipment, piping systems, and structural. Minimum weld spacing — the required distance between adjacent weld joints — is one of the most practically important yet frequently misunderstood requirements in pressure vessel, piping, and structural fabrication. In regulated industries, getting this wrong does not mean a minor non-conformance:. Welding is a fundamental process in many industries like oil and gas, construction, manufacturing, shipbuilding, automotive, and aerospace. Extracts from these standards are shown below and summarised in the following table: See below for notes on attachment welds.
