Joining materials using brazing machines

URN: SEMME3180
Business Sectors (Suites): Marine Engineering Suite 3
Developed by: Enginuity
Approved on: 2019

Overview

This standard identifies the competences you need to operate torch, inductance, resistance or furnace brazing installations that have already been prepared for production, in accordance with approved instructions or procedures.  You will be expected to check that the equipment has been approved for production and that sufficient supplies of all the required materials and consumables are present and correct and ready for production operations to be performed.

You must operate the installation safely and correctly, in accordance with instructions and approved procedures and achieve a joint quality and tolerances that meet the product specification.  You must continuously monitor the operation of the installation and make any necessary adjustments to equipment settings, in line with your permitted authority, in order to produce the brazed joints to the required specification.  Meeting production requirements will be an important issue and your production records must show consistent and satisfactory performance.

Your responsibilities will require you to comply with organisational policy and procedures for operating the brazing installation and to report any problems or adjustments to the installation that you cannot resolve, or are outside your permitted authority, to the relevant people. You will be expected to work with a minimum of supervision, taking personal responsibility for your own actions and for the quality and accuracy of the work that you produce. **     

Your underpinning knowledge will provide a sound basis for your work, enabling you to adopt an informed approach to applying brazing procedures and instructions.  You will have an understanding of how the brazing process works and is applied in mechanised form and will know about the equipment, materials and consumables, in adequate depth to provide a sound background to the process operation and for carrying out the brazing activities to the required specification. 

You will understand the safety precautions required when working with the brazing machine and with its associated tools and equipment.  You will be required to demonstrate safe working practices throughout and will understand the responsibility you owe to yourself and others in the workplace.


Performance criteria

You must be able to:

  1. work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
  2. follow the relevant joining procedure and work instructions
  3. confirm that the machine is set up and operating correctly, ready for the joining operations to be carried out
  4. check that the parent material, components, consumables and joint preparation comply with specifications
  5. carry out and monitor the machine operations in accordance with specifications and job instructions
  6. achieve joints of the required quality and specified dimensional accuracy
  7. make sure that the rate of output is as specified
  8. deal promptly and effectively with problems within your control and report those that you cannot solve
  9. shut down the equipment to a safe condition on conclusion of the joining activities
  10. complete relevant documentation in line with organisational
    procedures

Knowledge and Understanding

You need to know and understand:

  1. the safe working practices and procedures to be observed when operating brazing installations (including working with machinery; the use of appropriate personal protective equipment (PPE); machine guards; operation of machine safety devices; stopping the machine in an emergency; closing the machine down on completion of activities)

  2. statutory requirements, risk assessment procedures and relevant requirements of HASAWA, COSHH and Work Equipment Regulations; safe disposal of waste materials

  3. the hazards associated with brazing machines (including dangers from relevant equipment sources; fumes and gases; hot metal; moving parts of machinery) and how they can be minimised

  4. principles of the relevant brazing process; terminology used in brazing

  5. the key components and features of the equipment

  6. mechanised and automated brazing basics (such as types of installations; machine functions; safety features)

  7. how to extract the information required from drawings and brazing procedure specifications to include symbols and conventions to appropriate British, European or relevant International standards in relation to work undertaken)

  8. how to carry out currency/issue checks of the specifications you are working with

  9. operation of the machine controls and their function; care of equipment; control and storage of consumables

  10. setting up and aligning the workpieces

  11. monitoring the installation during the brazing process; recognition of problems, and actions to be taken

  12. problems that can occur with the brazing activities: materials, filler metals and joint defects

  13. self inspection of completed work

  14. organisational quality systems (such as standards to be achieved; production records to be kept)

  15. personal approval tests and their applicability to your work

  16. the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve
