Abstract
An instrumentation installation tool (30) for weldably attaching strain gages (20) or other instrumentation to the interior of a steam generator tube (42). The exterior surface of the section (32) is formed with four longitudinal grooves (32A, 36B, 36C and 38). A welding slot (44) is situated in one of the grooves (38). A ramp (46), oriented within the section (32) is in close proximity to the slot (44). Additionally, an elongated multitipped electrode (80) is slidably and coaxially disposed within the section (32).
