Re: [MW:35043] Material

Dear Saleem,

When planning to perform a Procedure Qualification Record (PQR) and develop a Welding Procedure Specification (WPS) using the E11018M electrode, it's essential to select an appropriate base material. The E11018M electrode is a low-hydrogen, iron-powder type electrode that is designed for welding high-strength steels.

Characteristics of E11018M:

• Classification: The "E" denotes an electrode, "110" indicates a tensile strength of approximately 110 ksi (110,000 psi), "18" specifies that it is a low-hydrogen electrode with iron powder, and "M" signifies it is designed for military or high-strength applications.
• Applications: This electrode is commonly used for welding high-strength, low-alloy steels in applications that require high mechanical properties such as military and aerospace components, as well as in heavy equipment, pressure vessels, and structural applications.

Suggested Base Materials:

For the E11018M electrode, you should choose materials that are compatible with the high-strength, low-alloy properties of the electrode. Here are some suggestions:

1. ASTM A514 (T-1) Steel:

   • High-yield strength and excellent weldability.
   • Commonly used in structural applications requiring high strength and toughness.

2. ASTM A517 Steel:

   • Used in pressure vessels and boilers.
   • Offers high strength and good weldability.

3. ASTM A710 Steel:

   • High-strength, low-alloy steel plate.
   • Suitable for applications requiring enhanced mechanical properties.

4. ASTM A709 Grade 100/100W:

   • Structural steel for bridges.
   • High yield strength and good weldability.

5. ASTM A572 Grade 100:

   • High-strength, low-alloy steel.
   • Used in structural applications.

6. HY-80, HY-100:

   • High-strength low-alloy steels used in naval applications.
   • Offers high toughness and good weldability.

Selecting the Material:

When selecting the material, consider the specific requirements of your application, such as strength, toughness, and environmental conditions. Ensure that the material's mechanical properties are compatible with the E11018M electrode's characteristics.

Summary:

For welding with the E11018M electrode, you should use high-strength, low-alloy steels such as ASTM A514, ASTM A517, ASTM A710, ASTM A709 Grade 100/100W, ASTM A572 Grade 100, or HY-80/HY-100. These materials will allow you to leverage the high tensile strength and low hydrogen properties of the E11018M electrode effectively in your PQR and WPS.

Re: [MW:35042] Welder qualification

Dear Saleem,

To determine whether you can use carbon steel (CS) material for welder qualification when you have a stainless steel (SS) Welding Procedure Specification (WPS) that is for P-8 to P-8 materials, we need to consider the relevant codes and standards governing welder qualification.

1. WPS and P-Number Groups: The Welding Procedure Specification (WPS) you have is for welding P-8 to P-8 materials. In the ASME Boiler and Pressure Vessel Code (BPVC) Section IX, P-Numbers are used to group materials for welding qualification. P-8 refers to a group of austenitic stainless steels.

2. Welder Performance Qualification: According to ASME Section IX, a welder's qualification is typically done to demonstrate their ability to produce sound welds. The welder qualification test should be performed using the same material group (P-Number) as the WPS. This ensures that the welder is proficient in welding the specific materials and processes described in the WPS.

3. Using Different Materials for Qualification: ASME Section IX states that a welder qualified on a specific P-Number material is not automatically qualified to weld materials of a different P-Number. Therefore, if you use carbon steel (which is typically a P-1 material) for the welder qualification, this would not qualify the welder for welding P-8 materials (stainless steel) according to the WPS you have.

Summary:

No, you cannot use carbon steel (P-1 material) for welder qualification if your WPS is for stainless steel (P-8 to P-8). The welder must be qualified using materials that fall within the same P-Number grouping as specified in the WPS, which in this case is P-8 (austenitic stainless steel).

Recommendation:

To qualify a welder for the SS WPS (P-8 to P-8), you should use austenitic stainless steel materials for the qualification test to ensure compliance with ASME Section IX requirements.

Dear Yasoob,

The statement appears to relate to a quality control or inspection procedure. Here's a more precise interpretation of the process:

1. First Test:

   • If one item fails out of a sample with a 10% failure rate, a secondary check (referred to as "Trecer" which might be a typo or specific jargon, possibly meant to be "Tracer") is performed with two additional items.

2. Second Test:

   • If either of the two additional items also fails, it indicates a problem, and the entire batch (or "full lot") must be inspected.

Here's a refined version of the process:

Initial Inspection:

• If 10% of the items in the sample fail the initial inspection, perform a secondary inspection with two additional items.

Secondary Inspection:

• If one or both of the two additional items fail this inspection, conduct a full inspection of the entire lot.

This process ensures that if an initial small sample indicates a potential quality issue, further scrutiny is applied to confirm the problem before deciding to inspect the entire batch, thus preventing defective items from proceeding further in the production or distribution process.

Re: [MW:35033] welder qualification

Dear Saleem,

As per the AWS D1.1/D1.1M:2020 Structural Welding Code – Steel, the qualification range for a welder who qualifies on a 6" diameter pipe with a wall thickness of 10.97 mm using the specified electrodes (E6010 for root and hot pass, and E7018 for the fill and cap passes) would be as follows:

Diameter Qualification Range

• When a welder qualifies on a pipe with a diameter of 6 inches, they are qualified to weld pipe diameters ranging from 2-7/8 inches (73 mm) and larger.

Thickness Qualification Range

• If the test coupon has a thickness of 10.97 mm (approximately 7/16 inches), the welder would be qualified to weld material thicknesses ranging from 3/16 inches (5 mm) to 2 times the thickness of the test coupon. This results in a qualification range of 3/16 inches to 21.94 mm (approximately 7/8 inches).

Summary

• Diameter Range: 2-7/8 inches (73 mm) and larger.
• Thickness Range: 3/16 inches (5 mm) to 7/8 inches (21.94 mm).

These ranges are determined based on the requirements set forth in AWS D1.1, which provides the necessary guidelines to ensure welders are properly qualified for a range of diameters and thicknesses beyond their test coupon. It is important to note that these qualification ranges are contingent on the specific procedure and test details as outlined in the AWS D1.1 code. Always refer to the latest edition of the code for the most accurate and detailed information.

Re: [MW:35018] thickness of WELDOLETS

Hi,

I have  a WPS for 6Mo with BM range 12.04 mm wall thickness max. Now i have a situation to weld a 2" weldolet on a 6" run pipe. Now weldolet groove thickness is measured to be 13.9 mm on the hub side. However the theoretical thickness is 11.905 mm. Can I weld this using the same WPS??

[MW:35020] Re: Use of Low alloy steels at high temps

this is not fully answer to your very elaborative question, but in short,

1. Low-alloy steels contain alloy element Cr, Mo, V, Ni

2. Low-alloy steels has a balanced compositions of above alloy element to resist  475C embrittlement, HTHA, Graphitization.

[MW:35022] I want to know the RT 10% acceptance criteria.

Dear Sir,

RT If one fails in 10% then there is a Trecer of two. And second time fails then check the full lot.

Re: [MW:35023] I want to know the RT 10% acceptance criteria.

Dear Yasoob,

The statement appears to relate to a quality control or inspection procedure. Here's a more precise interpretation of the process:

1. First Test:

   • If one item fails out of a sample with a 10% failure rate, a secondary check (referred to as "Trecer" which might be a typo or specific jargon, possibly meant to be "Tracer") is performed with two additional items.

2. Second Test:

   • If either of the two additional items also fails, it indicates a problem, and the entire batch (or "full lot") must be inspected.

Here's a refined version of the process:

Initial Inspection:

• If 10% of the items in the sample fail the initial inspection, perform a secondary inspection with two additional items.

Secondary Inspection:

• If one or both of the two additional items fail this inspection, conduct a full inspection of the entire lot.

This process ensures that if an initial small sample indicates a potential quality issue, further scrutiny is applied to confirm the problem before deciding to inspect the entire batch, thus preventing defective items from proceeding further in the production or distribution process.

Re: [MW:35025] Use of Low alloy steels at high temps

475 may not happen in low alloy steel.

Sigma phase formation will happen when --if %Cr-16%C/%Ni,     Less than 1.7, No sigma phase,  if it is more than 1.7 , Sigma phase
