    🕵️ Welding inspector is the person responsible for supervising all activities and duties and following up on all welding workers to ensure everything goes well Duties Of Welding Inspector’s main functions are his responsibility to monitor all aspects and procedures of welding operations and have been classified by experts especially TWI – CSWIP and the American Association of AWS – CWI The following: ⤵️

    1. pre welding

    2. stage while doing welding

    3. stage after finishing welding

    The goal of determining liability is to ensure that the welding is finalized according to the specifications and requirements of the code or criteria specified or according to the specifications of the project and the task is often pertaining to the visual inspection and should therefore be The inspector is great at assessing defects and results in general according to international standards and project related specifications. Here is a detailed explanation of all the tasks required of the welding inspector to perform.

    🎯 First: Inspector duties and duties before welding

    Welding inspector should review a list of all variables and operations before welding and it is not limited to the specifications of WPS welding so WPS can only be fully realized if equipment is available and other documents are available as well Optimization and inspection levels vary by consequential to the requirements of a certain code or standard and not limited to raising awareness of the team or helping solve problems but most often it is as follows :- ⤵️

    ▪️ Documents and Documents

    Confirming the latest versions of both geometric graphics, standards, and technical specifications.

    Check and correct the welding procedures qualified welding procedures and work on putting them in the right place and make sure there is the name of the welding process to be used.

    Making sure the welders and technicians are fully qualified to do this with the WPS

    Working on making sure there are special instructions documents on non-destructive testing and I’m already in the right place.

    Ensuring interpass welding or if necessary instructions on PWHT

    Making sure temperatures are set, temps are fixed, temperatures are measuring methods and so on.

    ▪️ Welding equipment and tools

    Making sure the welding machines are functional while checking the history and health of the calibration machine. There is usually some equipment that doesn’t have calibration screens, so it needs to be confirmed.

    Making sure all attached equipment like ovens, cables, crude flame in English ovens, quivers, remote controls, torches, cables works properly and has no faults

    If the subject needs PWHT, make sure thermal processing equipment is in place and it works properly and calibration is intact

    ▪️ Basic materials and consumer raw materials

    Ensure and verify that the correct material will be used and in an acceptable condition according to the specifications and criteria related to the project

    Certificates of production of materials in English, material certificates, indicate the correct numbers and grades that correspond to the nature of work, heat, etc.

    Verify other consumables such as welding wires, coated wires, or gas types used and properly prepared to the manufacturer’s specifications.

    Check any other consumer certificates and make sure they match work specifications

    ▪️ security, safety and environment

    Verified and committed to ensuring necessary precautions are taken on work permits and all required equipment for safety and security are in place

    Making sure all electrical equipment works correctly and not susceptible to electrical diamonds

    Making sure ventilation is good and enough in the workplace

    Ensuring security and personal protective equipment is properly and properly used

    ▪️ set up and fitting welding links

    Making sure the welding and joint links are set up according to the established procedures and using a certified style like flame cut, ground, machined, etc

    Making sure the sizes of welding and joint links are the right size in terms of angles groove angles, groove radius, root face, etc. All the root gaps and alignment are done according to proper procedures and this point has been adequately explained in welding codes.

    Ensuring the application of heating operations is attached to the required specifications and according to WPS welding procedures

    🎯 Second: liability, duties and functions of welding inspector (during or during the welding process)

    Welding inspector must monitor all aspects of actual welding process to make sure operations and inputs are properly applied and that welding is formed according to WPS welding procedure document and in fact it would be negligent to take all preparations and surveillance for pre and after tasks This simply doesn’t comply with the accuracy of the procedure and many welding operations failed because the operator doesn’t have a vision of the scale of the process so a detrimental effect on the mechanical properties of welded links so it’s one of the inspections and welding inspectors is to monitor all Participants while forming welding may have to carry out previous tasks including the following tasks:

    Monitoring and recording of welding dusty like power of power run-out lengths and measuring voltage

    Monitoring and recording environmental and climate conditions such as (rain – wind – snow – and other harmful weather factors) that can affect the form of final welding.

    Monitoring and maintaining regular temperatures including pre-heat temperatures.

    Ensuring the interpass is properly cleaned

    Check and monitor all interpass temperatures and maintain the required temperature

    Checking and monitoring all Root-run runs with heat monitoring

    🎯 Third: Duties and responsibility of welding inspector (post-welding stage)

    Once each welding is completed, one of the inspector’s responsibilities is to carry out the required inspections and tests by qualified staff and technicians to work while meeting the relevant code and criteria requirements and the most important of these tasks as follows.

    🔸 Ensuring PWHT thermal treatment is performed and applied by qualified people using proper procedures and equipment properly in some cases such as hydrogen crack requires thermal treatment before and after NDE non-destructive tests.

    🔸 Making sure NDT tests have been conducted and have been reviewed by welding inspector.

    🔸 Performing the optical inspection of completed welding, measurement, and related defects assessed according to the special criteria and specifications of the process

    🔸 keeping welding records with welding type and number

    🔸 Ensuring other tests such as pressure testing for pipelines, pipes, and pressure vessels after thermal treatment with results being recorded.

    🔸 Preparing necessary reports for the process.

    🔸 Taking all documents and documents related to the process and delivering them to the consultative office in charge of the project

    🎯 Fourth: Repairs after welding stage

    In case of a glitch or defects arise during inspections, there are three main options for a welding inspector. This actually depends on the size and severity of the flaws in welding, it can can cancel the welded item or give the defect permission to stay or Decides to fix the defect and cut the weld.

    Allowing and privileges

    This is the case where welding flaws are not very harmful and have no direct effects on welded elements so the welding inspector allows the defect to stay in place, and in some cases circumstances may require the circumstances to give the defect this privilege with a situation Certain restrictions on service and operation or other restrictions such as required to fix this defect later is more appropriate.

    Repair and adjustment

    In some cases welding process can require repair using different welding process, different consumables or a total change in WPS original wages and a number of repairs to these defects may be restricted depending on the material used so it should be close Repair procedure is written in detail what is required in the repair and adjustments process.

    In fact, the simplest way of adjustments and repairs is for inspector to monitor the repair process before, during and after welding and this gives greater guarantee that the repair will be done properly and that the welding will fit for the established action.

    🎯 V: More information about welding inspector’s duties 🎯

    At the end of this article on the duties and responsibilities of the welding inspector, I will quote you these sayings about the welding inspector from the TWI CSWIP book who said it is the duty of the welding inspector to ensure that all welding wages are implemented according to the established specifications and must

    Monitoring to monitor all welding related procedures at all stages of production

    Registration for all process-related checkpoints to ensure quality of welding production including final reports showing all defects identified.

    Reviews are comparing all recorded information with standards and other standard specifications that relate to welding and working on applying.

    I can also add some information about risks from gases during welding and thermal cutting since in doing these jobs, gas hazard is generated, usually gas is generated based on the process used and the operating mechanisms are therefore formed and established Dangerous in some operations and we use protective gas or shielding from atmospheric factors during molten welding or during cutting so gas is burned during consumption. In fact, there are many gases used within the scope of monitoring hazardous substances on health regulations as reported in COSH of 2002 which require some precautions during exposure and knowledge of the limits of gas exposure during welding operations and values are given in directive notes by the administration HSE health and safety and updated annually.

    Gas exposure can also be measured according to the methodologies mentioned in BS EN ISO 10882-2 for health, safety and environment during welding and similar operations by sampling airborne gas particles in the breathing area For the surroundings during operations, measurement is used to verify compliance with regulations and determine the need for surveillance with practical control systems to provide information about gas concentration and their health impacts and limit exposure to them besides welding and fumes exposure evaluation Other similar operations
