WELD ISSUES WITH IMPORTED COLD-FORMED TUBULAR SECTIONS

ECCS recommends to check very carefully the longitudinal weld thickness of imported cold-formed tubular sections, according to the limits that can be found in EN 10219 (Cold formed welded structural hollow sections of non-alloy and fine grain steels).
During TC9 meeting, ECCS has been alerted that the longitudinal weld of some imported cold-formed steel tubular sections has only 50% of required thickness, which is not allowed.
According to EN 10219-1 section 6.9.1, the weld thickness must be at least the minimum allowed wall thickness of the product. Recommended values of the minimum tube wall thickness is given in Table 2 of EN 10219-2
