transformer connection has priority to be finished/connected.

The non‐availability of crane of turbine hall due to restricted movement of the same. The sequence of

installation of connected components as a precondition of IPB erection. It might be necessary to be changed

with respect to transport of IPB into building, like for example the generator circuit‐ breaker.

The welding area must be cleaned (including paint removal) prior to welding. Cleaning (brushed or

scraped) has to be executed with a distance of approximately 50 mm to both sides of welding axis. Note:

Prescribed preheating temperature according to corresponding WPS has to be observed and followed. The

preheating is mainly assigned to welding of current‐carrying connections like:

• conductor connections

• grounding contacts

• short‐circuiting connections

Generaly: the Al material over 8,0 mm thickness has to be preheated.

Recommended method of manufacturer for preheating:

A required preheating shall be executed by means of flame of Butane or other suitable gas burner. The

electrical preheating is possible as well.

4.4.1.3.2 Execution of welding

Welding has to follow the corresponding Weld Joint Number of WPS. The corresponding Weld Joint

Number related to a weld is stated in the erection drawings (refer to chapter 4.4.1.4 for WPS of aluminium).
