Module Description: The aim of this module is to provide practical up-skilling along with related theoretical knowledge to personnel who currently have basic Tungsten Active Gas Shielded welding skills. This module will be limited to the welding of butt joints on carbon steel and stainless steel pipe.
 
Learning Outcomes
On successful completion of this module the learner will be able to:
# Learning Outcome Description
LO1 Identify and classify the various consumables used in Tungsten Active Gas Shielded welding of carbon and stainless steel.
LO2 Identify and prepare butt weld joints correctly.
LO3 Demonstrate the various techniques associated with Tungsten Active Gas Shielded welding in order to comply with welder qualification test EN 287.
LO4 Identify the reasons for and be able to purge a weld on stainless steel pipe.
LO5 Identify the various surface weld defects associated with Tungsten Active Gas Shielded welding, identify their cause and how they may be prevented.
LO6 Demonstrate the ability to successfully achieve the standard as defined by the specification EN 287.

Module Recommendations

This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named MTU module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
No incompatible modules listed
Co-requisite Modules
No Co-requisite modules listed
Requirements

This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.
Have completed a welding module of the National Craft Certificate Apprenticeship programme at phase 4 or 6, or have at least 2 years experience of welding at a basic level.
