Generalized Guidelines for
Structural Steel Welding
Inspection
As per AWS D1.1
Structural Welding Code: Steel
Standard Terms
CJP: Complete Joint Penetration
 PJP: Partial Joint Penetration

CJP
PJP
Fillet Weld
Scope
General Requirements
 Design of Welded Connections
 Prequalification
 Qualification
 Fabrication
 Inspection
 Stud Welding
 Strengthening and Repair of Existing
Structure

Limitation of Code
The code is not intended to be used for the
following:
 (1) Steels with a minimum specified yield
strength greater than 100 ksi (690 MPa)
 (2) Steels less than 1/8 in. (3 mm) thick.
 (3) Pressure vessels or pressure piping
 (4) Base metals other than carbon or low-alloy
steels. AWS D1.6, Structural Welding Code —
Stainless Steel, should be used for welding
stainless steel structures. Whenever contract
documents specify AWS Dl.l for welding
stainless steel, the requirements of AWS D1.6
should apply.

3.0 Prequalification of WPS
As per article 3 prequalification of WPS is exempt from
WPS qualification if following conditions are met
2. Welding Process: SMAW, SAW, GMAW (except
GMAW-S) and FCAW which conform to all of the
provisions of this section shall deemed as
l
prequalified.
3. Base Metal & Filler Meta Shall conform this table

Prequalification of WPS
4. Procedure approved by Engineer
5. Minimum Preheat & Inter-pass Temperature RequirementShall be as per Table 3.2 of page 68 (AWS D1.1: 2008
Code)
6. Limitation of WPS variables
“All prequalified WPSs to be used shall be prepared by the
manufacturer, fabricator or contractor as written
prequalified WPSs, and shall be available to those
authorized to use or examine them. The welding parameter
listed below shall be specified on the written WPSs .
Change in these parameter , beyond those specified on the
written WPS shall be considered essential changes and
shall require a new or revised prequalified written WPS

section,
other than Visual
Inspection no additional
NDT is required form
