Sir,
I looked up DIN EN 4133 in our companies library databased and it gave the title of the document as: "(DRAFT) Aerospace series - Bolts, normal hexagonal head, coarse tolerance normal shank, long thread, in titanium alloy, aluminium IVD coated - Classification: 1100 MPa (at ambient temperature)/425 °C".
This does not sound as if it has to do with welding. The issue date of the document is shown as 03/01/1995.
