Lampert welding wires for strong connections
Our welding wires are available in numerous alloys and material thicknesses and are suitable for a wide range of applications – including repairing surfaces, filling defects, restoring edges, bridging material gaps in a weld or hardening surfaces.
For good results with welding rods, note that cleanliness is the most important weld preparation:
- For a successful weld, it is very important that the welding area is carefully cleaned. Contamination, oxides, oil or wax layers make a good welding result impossible.
- The welds must be metallically clean. Depending on the contamination, chemical cleaning agents or metal-cutting processes are very suitable for cleaning the welds. In the case of light soiling or adhesions, cleaning by means of an ultrasonic unit is also recommended.
Welding wires for gold alloys
All welding wires for gold and platinum alloys are made of standard jewelry alloys with appropriate fineness. For typical jewelry manufacturing and repair applications, the welding wires must be processed very thinly in order to be able to apply the wires in a metered manner and at low power.

Welding wire for platinum
When welding Pt alloys, especially platinum castings, small pores and/or embrittlement can occur when welding repeatedly in the same place. This can be avoided by generally applying fresh metal using welding rod. When welding on platinum, a clean welding area and optimum shielding gas coverage are very important.
