Section 2 Welding Materials
201. Application
The requirements in this Section apply to tests and inspection for the welding materials in accord- ance with the requirements in Pt 2, Ch 2, 601. of the Rules.
202. Data to be submitted
The following reference data are to be submitted to the Society in addition to those specified in
102.
(1) The following data related to manufacturing process and quality control:
(A) In the case of covered electrodes:
(a)
Kind of welding materials, data on manufacturing process
(b) Data on type proportion of main component, shattering, mixing and churning of coating flux
(c)
Date on coating method, off-centering and drying methods
(d) Data on final processing
(B) In the case other than covered electrodes:
(a) Data on chemical composition, manufacturing process, acceptance criteria, wire drawing method and rust protection of core wire
(b) Data on main composition, manufacturing process, grain size distribution, etc. of flux
(c)
Data on manufacturer of welding wire, flux, etc.
(2) Data on storage method
(3) Data on packaging and marking
(4) Recent test records, or experiments and research data on welding materials for which approval is desired
(5) Data on the content of warning if they are provided against usage such as chemical composition of weldment, mechanical properties, welding current, welding voltage, welding speed, welding position, type of shielding gas, etc.
203. Type tests
Type tests are to be done in accordance with the requirements in Pt 2, Ch 2, Sec 6 of the Rules.
204. Periodical inspection
1. General
The manufacturer of welding materials is to be subjected to the periodical inspection in the pres- ence of Surveyor at each manufacturing plant within three months before or after the expiry of the validity.
2. Application for periodical inspection
Manufacturers are to submit to the Society an approval application from which includes for each brands of the welding materials (Marks of core wire in combination with flux for the case of auto- matic welding materials).
3. Items to be covered by periodical inspection
(1) The periodical inspections are to, in principle, be conducted at the manufacturing plant in the presence of the Surveyor.
(2) The test in periodical inspection is to be conducted in accordance with requirements of Pt 2,
Ch 2, Sec 6 of the Rules using the welding materials taken at random by the Surveyor.
(3) The periodical inspection is to be completed within the effective period of the approval certificate. However, for unavoidable circumstances, the periodical inspection may be completed within a period of three months after the expiration date upon the approval by the Society.
4. Test records
After completion of the test in periodical inspection the manufacturer is to prepare three copies of test records and submit them to the Society upon receiving confirmation by the attending Surveyor.
5. Withdrawal of approval
In case where periodical survey specified in 1 to 4 above has not been carried out, the Society may withdraw the approval.
205. Change in the approval content
1. Application for change
Application for change is to be treated in accordance with Pt 2, Ch 2, 601. 6.
2. Content of the tests
(1) Type tests and confirmation tests are to, in principle, be conducted at the manufacturing plant in the presence of the Surveyor.
(2) The additional type tests under the provision of 1 (1) afore-mentioned, are to be done in ac-
cordance with the following:
(A) Change of grade
The additional tests are to be
601. 3 (3) of the Rules.
(B) Addition of welding position Tests, of which test assemblies
done in accordance with the requirements of Pt 2, Ch 2,
are specified to be prepared for additional welding positions
in the provisions of Pt 2, Ch 2, 602. through 608. of the Rules, are to be done.
(C) Enlargement of maximum diameter of electrode or wire
Tests required are to be carried out at the largest diameter of electrode or wire in accord- ance with the requirements in Pt 2, Ch 2, 602. through 608. of the Rules.
(D) Addition of shield gas
Additional tests are to be done in accordance with the requirements of Pt 2, Ch 2, 603. 3, 604. 3, 606. 3 and 607. 3 of the Rules.
(E) Others
As deemed necessary, the tests required by the Society basing on the nature and extent of the change, are to be done.
(3) When confirmation test is required under the provision of 1 (2), the details of the confirmation
test is to be informed by the Society taking consideration of the nature and extent of the changes.
3. Submission of test record and certificate of approval
(1) Type test record and confirmation test record are to be submitted in accordance with 104. 5
and 109. 2 respectively.
(2) In case when items described in the certificate of approval is changed, the manufacturer is to return the certificate to the Society.
206. Packing and marking
The manufacturers are to be specially noted the following points on the packing and marking of the approved welding materials.
(1) The approved welding materials are to be packed thoroughly to keep the quality during their
transportation and storage.
(2) All boxes or packages of the approved welding materials are to be clearly marked with the fol- lowing descriptions together with the mark of approval by the Society.
