AWS Compliance : In-House Welding Qualification Test – SAW Flux Grade Compliance

This videos and photos showcase an in-house welding qualification test conducted to verify the grade compliance of our SAW flux. The objective is to ensure that every production batch performs exactly as declared, before reaching customers.

Quality Assurance Insight

This qualification test is not a one-time exercise. It is a mandatory quality check performed for every SAW flux grade developed and supplied by AV Weldtech, reinforcing our commitment to code compliance.

Observed Welding Characteristics (Code-Compliant Conditions)

• Easy and clean slag peel-off
• Smooth, shiny, and uniform bead finish
• Stable arc behavior throughout the weld

Welding Setup & Joint Details

• Welding Process: Submerged Arc Welding (SAW)
• Joint Type: Groove weld (test coupon)
• Base Plate Thickness: 25 mm
• Bevel Angle: 15°
• Root Gap: 12 mm

Consumables Used

• SAW Flux: AVEZEWELD 17L
• SAW Wire: EM12K – 4.0 mm

Welding Parameters

• Current: 500–550 A
• Welding Speed: 420 mm/min

(All parameters strictly maintained as per ASME BPVC requirements.)

Tests Conducted

The welded assembly is subjected to:

• Tensile testing
• Bend testing
• Impact testing at sub-zero temperatures
• Chemical analysis of weld metal

These tests confirm:

• Flux grading and classification
• Compliance with declared standards
• Repeatability and batch-to-batch consistency
