Training in Gas Welding (G)

Gas welding is principally used inorder to join plates and tubes madeof unalloyed and low-alloy steels. Inmost cases, the plate or tube-wallthicknesses to be welded are lessthan 6 mm.

This training path guarantees that the student receivescomprehensive practical training and theoretical education

and is thus qualified according to the requirements in practice(testing standard: DIN EN 287-1).

The main areas of application are:

- General pipeline construction- Heating engineering and ventilation technology- Boiler construction- Bodymaking and apparatus engineering

Comprehensive training to become a gas welder is possible byattending a according tothe DVS -IIW/EWF 1111 guideline. According to this training concept,

also specific demands for materials can be regarded.

Gas-shielded metal-arc gas weldingis used in almost all fields of metalprocessing. The area of applicationextends from the welding of sheets inbodymaking to the joining of thick-walled components in structural steelengineering and heavy-machineconstruction. In the case of steels,the weld pool is protected from theingress of air by active shielding gases(MAG). Non-ferrous metals are weldedusing inert shielding gases (MIG).

Comprehensive training for the metal-active gas welding (MAG) of unalloyed and low-alloy steels is achieved by attending the

according to the DVS -IIW/EWF-1111 guideline. According to thiscourse concept, the training measures for stainless steels andaluminium materials are also taken with modifications typicalof the materials.

Testing of WeldersOn the basis of the quality requirements on welding-technologyfabrication, the welding and acceptance regulations imposed bysupervisory authorities, monitoring bodies, classification societiesor the customer demand that welders prove their aptitude accordingto the following testing regulations.

The area of application of these welders' qualification tests isoriented towards the testing conditions.

An explanation of the testing structure is given on the following pages.

The purpose of welders' qualification tests is to ensure the quality of welding work. In the "governed area", the deployment of certifiedwelders is prescribed. In the "non-governed area", adequatelyqualified personnel are demanded by the requirements related toproduct liability.

Thus, the customer must pay precise attention to the requiredarea of application.

Why is a Welder's Qualification TestNecessary?

Purpose


19/28


E d i t i o n 0 9 / 2 0 0 5

Page: 17

Area of Application

For manual welds according to the G, E, MAG, MIG and TIG processeson components made of steel or aluminium,e.g. on

tank structures, hydraulic structures, rail andsteam boilers, pipelines, road vehicles,superstructures, tanks,bridge structures, naval structures,

the body responsible for the area of application (governed area)or the customer (non-governed area) demands the deployment

of certified welders.

Scope

The test applies to the manual skills and specialist knowledge of the welders.

Period of Validity

As a rule, the welder's qualification test has a validity of 2 years if theemployer or the welding supervisor responsible confirms every6 months in writing on the welder's qualification test certificate that

the welder welds regularly; (the max. permissible interruptionis 6 months),

the welder welds in the area of application of his/her welder's

qualification test,

the ability and knowledge of the welder are not in doubt.

The period of validity can only be extended by 2 more years if

the tester or the testing body is in possession of correspondingtest reports about the quality of the fabrication welds manufacturedby the welder, e.g. documents about radiographic, ultrasonic or fracture tests.


20/28

Page: 18


E d i t i o n 0 9 / 2 0 0 5

Theoretical Test

Every welder's qualification test involves a theoretical test section,including the following subject areas:

Prevention of accidents and fire damage

(BGR 500 Welding, Cutting and Allied Working Processes")Handling of the welding equipment according to the process:

In Gas Welding (G) In Arc Welding (E, MAG, TIG)Welding flame Influence of arc lengthWelding gases Welding amperage, polarityOperating techniques Magnetic arc blow, slag control(leftward, rightward) Shielding gases

Avoidance and elimination of defects during the welding processSteels, aluminium and alloys as well as their consumables,depending on the testWelding signs and welding symbolsPreparation of the workpieces for the welding processDesignation of a welder's qualification test and ist areaof application
