TigTectic-224

A High Nickel Filler Metal For Repairing Thin Section Gray Cast Irons and for Joining Castings To Steels ®

TigTectic 224

TIG ROD • General Purpose Rod for Cast Iron Joining, Build-up and Repair • Minimal dilution • Smooth, Dense, Machinable deposits

DESCRIPTION:

INSTRUCTIONS FOR USE:

TigTectic 224 is high quality, gas tungsten-arc rod for filling small casting defects, repairing minor cracks, re-building missing sections, and surfacing machined seats for followon machining.

Note: Optimum conditions for individual applications and welders should be determined by trial prior to the welding intended part or joint’

• Pump valve seats • Engine blocks with surface defects • Re-patching large-size holes • Cylinder head cracks between inlet and exhaust ports • Touch-up repairs

Preparation: Clean the joint and/or broken parts thoroughly. Lightly bevel cracks by grinding with minimal pressure to ovoid localized overheating. Align parts and secure where necessary. Complex or large parts should be supported by jigs. A nominal preheat of 200-250°F is recommended. Select a thoriated or lanthinated tungsten electrode, gas cup and filler diameter appropriate for the working thickness.

Tungsten tips ground to proper dimensions for better electrode life, arc control and bead consistency.

TECHNICAL DATA:

Note:This nominal preheat will help to prevent cold shutting or lack of fusion as well as reducing the amperage range with its associated dilution.

APPLICATIONS:

Classification: AWS 5.15 ERNi-C1 • Typical Tensile Strength 50,000 psi (450 N/mm2) • Typical Yield strength 38,000 psi (262 N/mm2) • Typical Hardness (HRB) 90 • Current & Polarity: DCEN (-) • Shielding Gas: Welding grade argon

Technique: Use a strike-plate to start the arc, scratching the tungsten tip with emery paper before re-strikes. Maintain and adjust the stand-off distance so that the molten pool is fully protected. Allow complete solidification before removing the filler rod or turning off the shielding gas.

Post-welding: Slow cool after welding using available insulating material such as vermiculite or heat-retardant blankets.

HEALTH AND SAFETY: Observe normal welding practices, respiratory protection and proper air flow pattern advised. For general welding practices, see AWS publications Z49.1 “Safety in Welding and Cutting and Allied Process”. Welding is a completely safe process when performed in accordance with proper safety measures. Become familiar with local safety regulations before beginning welding operations. DO NOT operate welding equipment or use welding materials before you have thoroughly read the proper instruction manual(s).

Please refer to the Eutectic internet site for Material Safety Data Sheet (MSDS) information.
