The "six welding positions" generally refer to the standard classifications defined by the American Welding Society (AWS) and ASME.

ASME Section II
ASME Boiler and Pressure Vessel Code Section II is divided into four parts: A, B, C, and D.

Each part covers different technical references used for material selection, welding, fabrication, and design calculations in pressure equipment.

__________________________________

●ASME Section II Part A

Ferrous Material Specifications

Covers:

Carbon steels

Low alloy steels

Stainless steels

Plates, pipes, fittings, forgings, bolts, bars, etc.


Main purpose:

Provides material specifications adopted from ASTM for ferrous materials.


Examples:

SA-516 → Carbon steel plate

SA-106 → Carbon steel pipe

SA-240 → Stainless steel plate


Typical use:

Selecting pressure vessel and piping metallic materials.

●ASME Section II Part B

Nonferrous Material Specifications

Covers:

Aluminum alloys

Copper alloys

Nickel alloys

Titanium alloys

Zirconium and others


Main purpose:

Provides specifications for nonferrous materials.


Examples:

SB-111 → Copper tubes

SB-265 → Titanium plate

SB-443 → Nickel alloy material


Typical use:

Corrosion-resistant or special __________________________________

●ASME Section II Part C

Welding Consumables

Covers:

Welding electrodes

Filler metals

Fluxes

Shielding gases


Main purpose:

Provides specifications and classifications for welding consumables.


Examples:

SFA-5.1 → Carbon steel electrodes

SFA-5.4 → Stainless steel electrodes

SFA-5.18 → GTAW/GMAW filler wires


Typical use:

WPS preparation

Consumable selection

●ASME Section II Part D

Properties (Design Data)

Covers:

Allowable stress values

Yield strength

Tensile strength

Elastic modulus

Thermal expansion

External pressure charts


Main purpose:

Provides mechanical and physical properties used in design calculations.


Typical use:

Pressure vessel thickness calculations

Piping stress analysis

Design temperature limitations
__________________________________

■Easy Way to Remember

A → Alloy/Steel

B → Beyond Steel (nonferrous)

C → Consumables

D → Design Properties

Here is a clear comparison image concept for WPS vs PQR vs WQT in welding:
*WPS (Welding Procedure Specification)*
* Describes how to perform the weld
* A workshop guide outlining welding parameters and essential variables such as welding process, base metals, filler metal, preheat/postheat, position, etc.
* Used as instructions for welders to follow for production welds
*PQR (Procedure Qualification Record)*
* A record of the actual tested welding procedure
* An office document listing the precise welding parameters and test results from a procedure qualification test weld
* Proves that the welding procedure can produce an acceptable weld and forms the basis for the WPS ranges
*WQT (Welder Qualification Test) or WPQ (Welder Performance Qualification)*
* Tests and qualifies the welder's ability to produce a sound weld using a WPS
* A practical test performed and documented to demonstrate the welder's skill
* Ensures the welder can reproduce the welding procedure within the qualifying ranges
*In summary*:
* PQR comes first as the tested procedure record
* WPS is derived from PQR, giving welding instructions for production
* WQT/WPQ certifies the welder's skill to follow the WPS
