GB/T 13148-2008Specification for welding of stainless steel clad plate (English PDF)

Foreword

This standard replaces GB/T 13148-1991 "stainless steel clad plate welding conditions." This standard compared with GB/T 13148-1991, the main changes are as follows:

--- Standard name changed to "stainless steel composite plate welding technology requirements";

--- Adjusted normative references;

--- Table 1 to informative A "composite stainless steel welding materials" Appendix;

--- Added two stainless steel composite butt groove type, four grassroots steel grades and a multi-layer steel grades;

--- Modified stainless steel clad steel plate butt joints at room temperature bending test provisions;

--- Modify the selection of welding materials at the grassroots first weld cladding;

--- Remove the prolonged absence of production and orders for primary steel 22g, 15MnVR and can use the same ingredients and base metal wire or mother Timber board cut wire strips as described;

--- Security to press GB 9448 "welding and cutting safety" requirement. Appendix A of this standard is an informative annex. The standard proposed by China Shipbuilding Industry Corporation. This standard by the National Standardization Technical Committee of marine vessels marine materials application technology at the Technical Committee. This standard was drafted.

1 Scope

GB/T 13148-2008 is the Chinese national standard on specification for welding of stainless steel clad plate, in the field of shipbuilding and marine structures. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 30 July 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 February 2009. Classification: ICS 47.020.01, CCS U05. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the material of stainless steel clad steel welding, welders, welding preparation, welding process, welding quality inspection and welding defects back Repair and other technical requirements. This standard applies to stainless steel cladding to carbon steel or low alloy steel for the base layer is not less than the total thickness of 4mm stainless steel composite Welded steel plate.
