Projection Welding Testing Procedure. PrEN ISO 15614-12 Specification and approval of welding procedures for metallic materials - Welding procedure tests - Part 12. Welding technique weld progression bead overlap etc.
Assessment of weldability for resistance spot seam and projection welding of metallic materials. It is a straightforward process and all the welds can be made with a single electrode. Among the test are tension and bend tests made on specimens of a certain shape.
Testing of welds is used to verify that the welding procedure is under control.
It is a straightforward process and all the welds can be made with a single electrode. Used during test weld replicates those found in the production environment. Short length T joints eg. Brackets spigots and weld nuts to sheet metal where there is access from only one side and for making attachments to solid forged or machined parts.
