DOT Part 192

• DOT Part 192 • Subpart E Welding of Steel in Pipelines • 192.225 Welding Procedures

(a) Welding Must be performed by a qualified welder in accordance with welding Procedures qualified under section 5 of API 1104 (incorporated by reference, see 192.7) 192.7 / B. American Petroleum Institute (API)

(b) Each welding procedure must be recorded in detail, including the results of the qualifying tests. This record must be retained and followed whenever the procedure is used.

Test Welds to Qualify Welding Procedures shall be determined by destructive testing.

DOT Part 192

• 192.241 Inspection and Test of Welds (a) Visual inspection of welding must be conducted by an

individual qualified by appropriate training and experience to ensure that: 1) The welding is performed in accordance with the welding

procedure; and 2) The weld is acceptable under paragraph (c) of this section.

(c) The acceptability of a weld that is non-destructively tested or visually inspected is determined according to the standards in Section 9 of API 1104

• 192.143 Nondestructive Testing • Must be performed by any process, other than trepanning,

that will clearly indicate defects that may affect the integrity of the weld

• 192.245 Repair or removal of defects • Defect removed down to sound metal • After repair inspected to ensure its acceptability • Repair in a previously repaired area must have a separate

procedure

State Requirements

• New Hampshire • 500 Rules

• Utility shall ensure & document welders are qualified • Welder qualified by destructive testing with-in preceding 63 months at least 5 years • Engaged in welding with that process with-in the preceding 6 months

• All welds are visually inspected by qualified welding inspector in accordance with API 1104 section 8.3

• Projects operating greater than 60 pounds require 10% NDT of projects that consist of at least 10 welds ; or

• NDT field test on at least one weld for projects that include 5 to 9 welds • Any weld failure will require no less than 50% of all welds any additional failure will

require 100% NDT

• Massachusetts • 220 CMR

• Visually inspections of welds shall be performed by qualified welding inspector • Record or each NDT or visual inspection for life of pipeline • 6”greater shall be NDT • All pipeline tie-in welds shall be NDT

• Maine • 65-407 PUC Chapter 420

• 192 provisions

To work for multiple companies you need to know what procedure, O&M

Our O&M states MUGP-1, welder certifications were done with the NGA procedures can he weld you.

Two things have to happen:

1) Need to see if welder essential variables were met a) change from one welding process to a different welding process

b) Change in the combination of welding process

c) Change in the direction of welding uphill to vertical downhill

d) Filler-metal classification group 1&2 to group 3

2) You have to follow their welding procedures, in this case will be MGUP-1
