Weld analysis — Jun 1, 2026

Educational visual feedback on a sample practice weld.

AI summary

This GTAW practice weld appears to show a couple of areas worth attention, alongside real strengths. The face appears slightly below flush in sections, which may indicate underfill. Overall consistency looks reasonably steady. Focus on the priority improvement below, run the suggested drill, and submit a comparable weld to measure the change. Remember: surface appearance cannot confirm what is happening inside the joint.

Puddle still slow to wet in at the start. Next session: preflow a touch longer and try 135 A for the first inch, then back off.

AI observations

Educational guidance only

AI-assisted visual feedback is educational guidance only and is not always accurate. A photograph cannot confirm code compliance, structural integrity, internal fusion, penetration, or test results, and it is no substitute for hands-on inspection. Have a qualified instructor or inspector evaluate any weld that matters.

Photo quality & limits

Feedback quality depends on what the camera captured. Anything below the surface is outside what a photo can show.

Image rating:Excellent

What shaped the confidence level

  • Welding details were provided, which sharpens interpretation.
  • The photo is clear and well lit.

What this review cannot tell you

  • Internal soundness, fusion, and penetration can never be judged from a photograph.
  • Lighting and angle can hide or exaggerate surface conditions.
  • This educational feedback is not an inspection and does not assess code acceptance.

What looks good

Strengths visible in this photo — keep building on them.

  • The stop shows attention to filling the crater.
  • Bead placement tracks the joint line well.
  • The work area and plate look properly prepared.

Priority improvements

Work these in order — each one builds on the last.

Why it matters

The face appears slightly below flush in sections, which may indicate underfill.

How to practice it

Build baseline arc control and consistency.

Possible concerns

Visual indications only — a photo cannot confirm whether a discontinuity is actually present or how deep it goes. Where your instructor weighed in, their call is labeled and takes priority over the AI.

  • Possible underfill

    PossibleModerate

    Location: intermittently along the bead

    The face appears slightly below flush in sections, which may indicate underfill.

  • Inconsistent bead width

    Appears presentModerate

    Location: intermittently along the bead

    Bead width appears to vary noticeably along its length.

Suggested practice drill

Stringer-bead pads

Build baseline arc control and consistency. Fill a 4×6 in plate with parallel stringer beads, each overlapping the previous by one-third. Focus on a steady arc length and even travel. Photograph the pad and compare ripple consistency to your last session.

Technique & equipment

Technique suggestions

  • Keep your arc length equal to about the electrode/wire diameter and check it whenever the sound changes.
  • Watch the back edge of the puddle rather than the arc itself.
  • Brace your hand or forearm so travel comes from your whole arm, not your wrist.

Equipment considerations

  • Consider whether 130 A gives you puddle control within 2-3 seconds of arc start; adjust in small steps.
