What is group number?
A) Your Group Number is the number found on your health insurance ID card that is unique to your company.
Everyone who has insurance through your company will have the same group number.
This unique number allows health care providers and pharmacies verify your coverage..
What are P numbers in welding?
Base Metals: The P Number This number is used to group similar Base Metals, allowing qualification of an entire selection versus qualification of just one. These base metals are grouped by material and assigned P Numbers based on what material they are.
What is the difference between P number and group number?
The main difference between the two is that the ISO system allows any material within the scope of the reference standard to be assigned to a certain group, whereas the ASME system assigns a P-No only to materials listed in the code or that have the same UNS number as listed materials (see below for more details).
What is f1 welding?
An architect’s blueprints would indicate the welding symbol. 1 refers to a flat position – either 1F or 1G. 2 refers to a horizontal position – either 2F or 2G. 3 is a vertical position – either 3F or 3G. 4 is an overhead position – either 4F or 4G.

What is p3 material?
AISI P3 is a Low-Carbon Mold Steel grade Tool Steel. … Wrought steels are the most common engineering material used, and come in a variety of forms with different finishes and properties. Tool steels typically have excess carbides (carbon alloys) which make them hard and wear-resistant.
What is the P number for Alloy 20?
45The P Number of Alloy 20 is 45 according to ASME BPVC Section IX.
What is P number in WPS?
Frequently asked questions. To reduce the number of welding procedure qualifications that are required, P-Numbers (shortened to P-No) are assigned to base metals according to the characteristics of the material, such as composition, weldability, brazeability and mechanical properties.
What is SFA no in welding?
So really all the SFA # is the A numbers that a particular consumable conforms into. In case you were wondering. 5.1 carbon steel. 5.4 stainless steels. 5.8 alloy steels.
What does F mean in welding?
The F number grouping of filler metals refers to their similarity on their usability characteristics. … Like the P number, the F number designed to reduce the number of procedure qualification and welding performance qualification.
What is a number in ASME?
1) The A-Number: The A-Number is a calculated value based on a combination of the chemical composition of the weld filler metal (which may be found in ASME Section II Part C), and ASME Section IX’s A-Number Table QW-442.
What is QW in welding?
A-Numbers are defined in (QW-404.5) as the chemical composition of the weld deposit. A-numbers are applicable only for the ferrous metals for the qualification of the WPS. They are not a variable for WPQ. A partial listing of A-Numbers by type of weld metal analysis can be found in (QW-442)
