Welding wires
The alloys and dimensions of Lampert‘s welding wires have been specially selected to complement the PUK,
and are ideally suited to welding with PUK precision welding devices.
Welding wires for gold alloys
All welding wires for gold and platinum alloys consist of standard jewellery alloy with the requisite degree of fineness. For typical applications in jewellery production and repair, the welding wires must be processed such that these are very thin, in order that the wires can be applied controlled and with low power.
Au 750 Y – Yellow gold Au 750/000 – 18K – 500mm x 0.25mm (19.7“ x 0.01“) 304 340
Au 585 Y – Yellow gold Au 585/000 – 14K – 500mm x 0.25mm (19.7“ x 0.01“) 304 341
Au 750 Pd – White gold Au 750/000 – 18K – 500mm x 0.25mm (19.7“ x 0.01“) 304 342
Welding wire for platinum
When welding Pt alloys, in particular with cast platinum, small pores and/or brittleness can arise if welding repeatedly takes place in the same place. This can be avoided in general terms through the application of „fresh metal“ with welding wire. When welding on platinum, a clean welding area and optimum shielding gas coverage are very important.
Pt 960 C – Platinum Pt 960/000 – 500mm x 0.5mm (19.7“ x 0.01) 304 343
Welding wire for silver alloys
The welding wire for silver alloys is alloyed with a high content of fine silver, in order to positively influence the
flowing characteristics and the ductility of the welding wire. However, the wire is the same colour as sterling silver
(925/000). The fineness of the welding wire is 940/000.
Ag 940 B – Silver Ag 940/000 – 1000mm x 0.35mm (33.37“ x 0.014“) 304 344
Welding wire for titanium
Unalloyed titanium wire (grade 2) for homogeneous welding on weldable titanium qualities. The wire is outstanding
due to its high crack resistance. When welding on titanium, a clean welding area and optimum shielding gas coverage
(with Argon 4.6 or higher) are very important.
Titanium – fine titanium – 1000mm x 0.30mm (39.37“ x 0.012“) 304 310
Welding wire for tin
The welding wire from fine tin 99.9% is suitable for repairs on objects from tin and tin alloys. The high purity of the
wire guarantees a very ductile and therefore stable and clean weld. It is advisable to process the welding wire with
an increased gas flow and larger gas nozzle (art. no. 100 150-4).
Tin – fine tin 99,9% – 100g x 0.75mm (3.52oz x 0.029“) 304 328
Welding wire for copper materials
Free-flowing copper alloy (C45) for smooth, dense and non-porous welding on copper, copper-zinc and copper-silicon alloys and for deposition welding on copper alloys and unalloyed ferrous materials. Corrosion resistant and very strong weld metal – very tough at low temperatures. Virtually identical in colour to pure copper.
Copper – Cu-Si3-Mn1 – 2000mm x 0.5mm (78,5“ x 0,02“) 304 313
Welding wires for steels
The welding wire CMS is a highly stable, austenitic welding metal. It is suitable for welding CrNi steels such as
1.4301, 1.4401, 1.4453 and 1.4571.
Steel CMS – stainless steel 1000mm x 0.40mm (39.37“ x 0.016“) 304 320
The welding wire GS2 is suitable for applications with a higher hardness on tools subject to heavy wear and pressure.
It is also good for platings on unalloyed and low-alloyed steels. Hardnesses up to 58HRC.
Steel GS2 – 1000mm x 0.20mm (39.37“ x 0.008“) 304 321
The welding wire GS55 is a martensitic chromium steel with good stability and wear resistance. It is suitable with
shock and impact stress and is heat treatable. For highly wear-resistant application welding on tools. Hardness’s up
to 61HRC.
Steel GS55 – 1000mm x 0.20mm (39.37“ x 0.008“) 304 322
Welding wires for aluminium
Welding wire ALMG3 for applications on Al-Mg alloys up to 3% magnesium e.g. AlMg3. The welding metal can be
anodised.
ALMG3 – 2000mm x 0.5mm (78.70” x 0.02”) 304 325
Welding wire ALSI for connections and application on aluminium-silicon alloys up to 12% Si, and for different types
of aluminium alloys together.
ALSI <12% – 2000mm x 0.5mm (78.70” x 0.02”) 304 326
ATTENTION – cleanliness is the most important preparation for welding:
It is very important that the welding area is carefully cleaned for successful welding. Dirt, oxides, oil or wax layers make good welding results impossible. The welding spots must be metallic-ally clean. Depending on the contamination, chemical cleaning products or machining processes are highly suited for cleaning the welding areas. With minor soiling and adhesion’s it is also advisable to clean with an ultrasonic device.
Welding wire for repairs and alloys that are difficult to weld . This Pd/Ag/Cu welding wire with a high portion of palladium is particularly well-suited for repair welds on alloys that are only weldable to a limited degree with themselves or with each other. The welding wire stands out due to its excellent adhesion properties and exceptional toughness. It is therefore frequently used as a „bridging metal“ between alloys that are difficult to weld (colour grey).
