Specialy Formulated TIG Rod for Enhanced Corrosion Oxidation Resistance ®
TigTectic 6800
TIG ROD • Ideal for hi-temp oxidization resistance up to 1800°F • Good nitric acid and chloride corrosion resistant • Excellent comparative mechanical properties
DESCRIPTION:
INSTRUCTIONS FOR USE:
TigTectic 6800 TIG rod deposits weld metal high in corrosion resistance to nitric acid and chloride-containing solutions. Excellent high-temperature oxidation resistance up to 1800°F.
Preparation: Clean joint and/or broken parts. Lightly bevel cracks by grinding.
APPLICATIONS: • Hot working blocker dies • Die rings • Pump vanes • Shear blades • Trim tools • Pickling & plating tanks • Pressure valves • Press punches

Note: The selection of the preferred thoriated or lanthium tungsten electrode diameter will depend on the material thickness and corresponding amperage range. This applies similarly to gas cup size. Note: Make sure that the tip of the electrode is ground with the proper taper for better heat localization. Preheating is normally not required when welding high nickel alloys. For tool steel welding refer to the Reference Section for recommended preheat and inter-pass temperatures. Technique: Adjust argon shielding gas flow. Complex or large parts should be supported by jigs. Use a copper arcstarting block to prevent random arc strikes and consequential hard- spotting. Adjust the stand-off distance so that the molten pool is always protected by the shielding gas and allow the rod/wire-end to solidify before removing from the protective gas envelope. Post-welding: For air-hardening steels slow cool using available insulating materials. For less-sensitive base metals, slow cool out of drafts.

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. DISREGARDING THESE INSTRUCTIONS, AND/OR THE INSTRUCTIONS OF WELDING EQUIPMENT OR MATERIAL MANUALS, MAY BE HAZARDOUS TO YOUR HEALTH.
