However, if the company wishes to obtain the CE marking of the structures it manufactures, the external Notified Body will be the one to evaluate the professional capacity of the designated coordinator and his real knowledge in welding techniques and their management. sting-penetrating-liquids-blogseas Imperfection detected using penetrating liquids on a weld that must be evaluated. 4.- What tasks should the welding coordinator assume? The activities to be carried out by the welding coordinator are described in the UNE-EN ISO 14731 standard (“Welding coordination. Tasks and responsibilitie).
These responsibilities extend throughout all phases of manufacturing the welded component , beginning with the documentary review of the contract signed with the client and the design of the welded construction, ensuring that your Saint Helena Email List company has the capacity to meet the client's requirements and achieve the level of quality required for the type of construction in question, since a small structure for an agricultural warehouse is not the same as a pedestrian walkway. On the other hand, you will be in charge of validating the base metals (adequate weldability, correct identification, storage and traceability) and consumables , such as protection gases or electrodes (compatibility with the base metal and supply conditions, among others). You must evaluate the suitability of the companies you subcontract , such as auxiliary workshops, testing laboratories or non-destructive inspection companies. You will also plan production , ensuring the suitability of the welding procedures to be applied, the proper qualification of the welders who will be involved, the type, timing and quantity of inspections and tests to be carried out on the welding to be carried out.
You will verify the availability and suitability of the welding equipment and auxiliary equipment to be used. You will check the correct execution of the activities prior to welding , such as edge preparation, assembly and spotting, or surface cleaning. During welding, you will ensure the correct assignment of welders , use of equipment, accessories and consumables , application of appropriate welding parameters , preheating times and temperatures, and welding sequence. At the end of welding, you must be in charge of the visual examination of the cords (appearance and dimensions of the cord, tolerances of the welded component, deformations,...) and the destructive tests (traction, bending, resilience, hardness, macrography) and non-destructive tests. (penetrating liquids, magnetic particles, ultrasound, x-ray) that must be performed. radiography-blogseas X-ray of butt welded joint with fusion failures With all this, you will accept the welds , based on the evaluation of the inspections and tests carried out or, in case of rejection, you will propose the corrective actions to be applied and you will manage the repair of the welds and their re-evaluation.
