TinWeld-2

A High-Tin, Lead-Free and Cadmium-Free Paint-On Paste Alloy ®

Eutectic TinWeld 2

BRAZING • Excellent for “tinning” of large surfaces to enhance surface protection • Good for use on food handling and sanitary equipment • May be used to solder braided electrical conductors • Will not turn black like lead-bearing solders

DESCRIPTION:

TYPICAL APPLICATIONS:

Eutectic TinWeld 2 is paint-on alloy for ‘tinning’ large surfaces to enhance surface protection and to promote batch soldering with pre-tinned and cadmium-plated parts. Can be used when soldering braided electrical conductors when post-cleaning is feasible.

For parts needing a pre-placement solder with a good speadability and low application temperature. Because the solder is both lead-free & cadmium-free it can be used on food handling and sanitary equipment. Note, too, that Eutectic TinWeld 2 does not turn black like lead-bearing solders.

SOLDERING PARAMETERS:

HEALTH AND SAFETY:

Preparation: Clean joint area with RotoClean OS or use a proprietary VOC-free solvent. Thoroughly mix the TinWeld 2 so that the flux and metal particles are well amalgamated and show a smooth consistency. Use a fine brush or spatula to apply the paste. Note, too, that it is important not to allow any movement while the solder alloy cools and solidifies.

Observe normal soldering, brazing and 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).

Technique: Heat insert parts slowly and indirectly to reduce thermal shock so to promote uniform flow. During the melting phase it is important that the parts being soldered to not move. Observe flow indications so that all contact surfaces are seen to be brazed and flow-through is evident.

When tinning surfaces make sure to heat indirectly to prevent flux charring. Wiping with a rosin-impregnated cloth will help to smooth the surface

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.

Post-brazing: Allow parts to cool naturally. Parts can be quenched to help with flux residue removal. For a more thorough job please refer to Eutectic 1001 Pre/Post cleaner.

TECHNICAL DATA: Typical Tensile Shear Strength: 10,000 psi 70 N/mm2 Electrical Conductivity - IACS: 15.6% Thermal Expansion Coefficient: 22 x 10-6 in/in°F (20-212°F) (-6.6-100°C) Solidus Temperature¹: 450°F (230°C) Liquidus Temperature²: 450°F (230°C) Maximum Brazing Temperature: 470°F (245°C) Heating Methods: Oxy-fuel torch, induction, resistance heating and furnace soldering ¹ The solidus temperature is the highest temperature at which the part remains solid i.e. the start of melting. ² The liquidus temperature is the lowest temperature at which the part is molten i.e. complete melting.
