Understanding the Welding Trade Test
A welding trade test is an objective practical examination designed to determine whether a welder can produce defect-free joints in accordance with industrial welding procedures (WPS).
Root Pass Penetration
Evaluators inspect the internal root bead for complete penetration, uniform reinforcement (1.5mm–2.5mm), and zero burn-through or root concavity.
Visual Quality Inspection
Surface inspection checks for lack of fusion, undercut, cold lap, excessive spatter, uniform bead width, and proper tie-ins at stopping points.
NDT & Mechanical Bend
Coupons often undergo radiographic testing (X-ray) or guided root and face bend tests (180° bend) to detect hidden internal slag inclusions or cracks.
Workshop Safety & Hygiene
Booth cleanliness, cable management, correct shade lens usage, proper chipping hammer handling, and PPE compliance are actively monitored.
Educational Distinction
General trade testing standards (such as ASME IX or AWS) govern universal welding expectations. However, specific client delegations may set custom acceptance thresholds (e.g., maximum allowable weave width or interpass cleaning restrictions). Always ask the center administration for specific test guidelines.
CS Multi Welder Test
A Carbon Steel (CS) Multi Welder is among the most sought-after trade classifications in power plant construction, oil refineries, and heavy mechanical fabrication. The CS Multi test assesses a candidate’s competence in switching seamlessly between two distinct welding processes on a single pipe coupon:
Using ER70S-6 filler wire, the welder deposits a continuous, fully penetrated root bead inside the pipe bore, followed by a thorough hot pass to consume any remaining tack edges and establish a strong foundation.
Using low-hydrogen electrodes (typically AWS E7018), the welder fills the bevel grooves in balanced stringer or controlled weave beads, finishing with a smooth, uniform reinforcement cap that blends cleanly into the parent metal.
Questions Candidates Should Ask Before Testing:
- What pipe diameter and wall schedule will be tested (e.g. 2-inch Sch 80, 6-inch Sch 40)?
- Is the test conducted in the 6G inclined fixed position or 5G horizontal fixed position?
- Are coupons subject to visual evaluation only or mandatory laboratory radiography?

Stainless Steel TIG & Alloy Welding
Strict argon purge backing to eliminate root oxidation (sugaring)
SS Multi Welder Test
Stainless steel pipe welding demands far higher precision, hygiene, and thermal discipline than carbon steel. Stainless steels (typically Austenitic 304L, 316L, or duplex alloys) are sensitive to heat buildup, warping, and atmospheric contamination at molten temperatures.
The primary technical challenge of the SS Multi test is internal shielding. When stainless steel is molten, contact with oxygen causes severe oxidation on the root side—a defect known in the trade as "sugaring". To prevent this, examiners enforce strict internal argon back-purging using inflatable bladders or water-soluble purge dams.
* Note: Stainless steel test availability depends on current project demands and consumable stock. Candidates must contact Ashtar to confirm SS test sessions.
Technical Comparison: CS Multi vs. SS Multi Welding Tests
| Inspection Parameter | CS Multi Welder (Carbon Steel) | SS Multi Welder (Stainless Steel) |
|---|---|---|
| Base Material | Carbon Steel (ASTM A106 Grade B, API 5L) | Austenitic Stainless Steel (304L, 316L, 321) |
| Purging Requirement | Generally open atmosphere (no internal purge needed) | Mandatory 99.99% pure Argon back-purging (O2 < 0.5%) |
| Root Pass Process | GTAW (ER70S-6 wire) or Cellulosic/Basic SMAW | Strictly GTAW (ER308L / ER316L wire) with continuous purge |
| Interpass Temperature | Up to 250°C permissible depending on wall thickness | Strictly controlled below 150°C to prevent carbide precipitation |
| Fill & Cap Pass | SMAW (E7018 low-hydrogen electrodes) | GTAW or SMAW (E308L-16 / E316L-16 electrodes) |
| Cleaning & Brushing | Standard carbon steel wire brushes and grinders | Dedicated stainless steel wire brushes (zero cross-contamination) |
Pipe Welding Trade Testing & 6G Mastery
Unlike plate welding, pipe welding requires continuous adjustment of the torch and rod angle as the welder moves around the circumference of the cylinder. Welds must pass through flat, vertical, and overhead positions within a single continuous run.
The international gold standard for pipe welder qualification is the 6G position. In 6G, the pipe is inclined at a fixed 45° angle and cannot be rotated. Passing a 6G pipe test qualifies the welder to work in all positions (1G, 2G, 5G, and 6G) under ASME Section IX, making 6G welders top candidates for oil and gas refinery projects.
