Manual Metal Arc Welding (MMA)

Manual Metal Arc Welding (MMA) Our welding training focuses on developing practical welding capability such that trainees achieve a consistent standard. The courses provide an intense but comprehensive course of welding instruction for those with some or minimal welding experience. They are designed to promote practical welding proficiency and provide trainees with a sound theoretical understanding of the process.

Our welding bay is fully ventilated with local and area extraction. On completion of the course trainees will be expected to be able to produce finished welded joints to an acceptable standard. Candidates can also be tested to the Welder Approval Standard BS4872 if required. This is an accepted and widely used standard ideally suited to maintainers and welders alike. Practical Work:

• Safe setting up of arc welding machine including electrical settings and polarity
• Striking of arc and deposition of weld material in FLAT, HORIZONTAL/VERTICAL, VERTICAL, and OVERHEAD position.
• Making simple joints in these positions as appropriate:
• "T" Fillet, Open Vee Butt, Close Square Butt, Lap weld
• With and without edge preparations as appropriate
• Using RUTILE, IRON POWDER and LOW HYDROGEN electrodes
• Using low carbon steel manufactured to EN43A of varying thickness (6mm - 8mm - 10mm - 12mm)
• Recognising Simple weld faults
• Testing completed weld joints

Theoretical Work:

• Instruction in the safe and correct use of the MMA equipment
• Identifying and selecting the correct type of welding rods for the process
• Understanding the requirements of current setting, rate of travel and arc length
