AS/NZS 1554.1-1995 structural steel welding - welding of steel structures

Standard Number:  AS/NZS 1554.1-1995
Title:  structural steel welding - welding of steel structures
Language:  English
Status:  Withdrawn
Publisher:  Australia Standards(AS)
Price:  
Number of Pages:81  

Preface:   
Description:Specifies materials of construction, weld preparations, weld qualities, qualification of welding procedures, qualification of welding personnel and, fabrication and inspection requirements for welds related to the arc welding of steelwork in structures made up of combinations of steel plate, sheet or sections, including hollow sections and built-up sections or castings and forgings. Tables of weld preparations are given for both butt and fillet welds which when welded in accordance with other specified requirements are deemed prequalified and do not require qualification testing. Provides two categories of welds based on the type of application.
