Are you a professional welder or do you have a team of welders in charge? So it is important that you know in which cases it is mandatory for a welder to be “approved”, that is, qualified as a welder according to the ISO 9606 standard. The approval of a welder implies that this professional has passed the tests to which he has been subjected to evaluate his skill . These tests depend on the type of welding to be performed; but, basically, they consist of welding two pieces together (what is called a “test coupon”). A series of non-destructive tests (visual inspection, radiographic and/or ultrasound examination) or destructive tests (bending, fracture and/or macrography) are carried out on this test coupon. If the result is satisfactory, the welder is qualified (“approved”) and the corresponding “welder qualification certificate” is issued. Image_01: X-ray of a test coupon for welder qualification. That a welder is “approved” implies that he is capable of making welds with the required quality, which is of vital importance in most cases, unless this professional is dedicated only to making aesthetic welds (for metal furniture , simple locksmithing, etc.), which will not have to withstand significant loads or efforts.
The qualification of welders is carried out following the principles included in the international standard ISO-9606 entitled “Qualification Cayman Islands Phone Number List of welders. Fusion welding” and has two parts: the first for steel welds and a second for aluminum welds. If you are professionally dedicated to welding metal structures that are going to be used in construction , whether for industrial buildings or residential or commercial buildings, the welders must be qualified. This is indicated by the UNE-EN 1090 standard , regarding the CE marking of steel and aluminum structures, mandatory since July 1, 2014. It literally says that “ all structures to be used as load-bearing parts of works designed to provide resistance are affected.” mechanics and stability and/or resistance to fire (…) that can be incorporated into a building or civil engineering work.
It can be a beam, a pillar, a railing, the rebar used in reinforced concrete, etc., etc. Specifically, this standard indicates that “ welders must be qualified in accordance with the ISO 9606 standard and welding operators in accordance with the EN 1418 standard .” This is also stated in the Technical Building Code (CTE) which, in its Basic Document SE-A on Structural Safety of Steel, specifies that “ welders must be certified by an accredited body and qualified in accordance with the ISO 9606 standard. ”.

Therefore, if your activity is related to construction , you must be “approved . ” In the event that your professional activity is outside the field of construction, it is very possible that the products you weld are destined for the manufacture of vehicles , both road and railway. Manufacturers of welded vehicle components must be certified in accordance with international standards ISO 3834 ( Quality requirements for fusion welding of metallic materials ) or ISO 15085 ( Railway applications.
