Stable Wire Feed, Extended Eifetime:
SVS Standards for SAW Contact Tips
A precisely toleranced guide bore keeps the wire on track and prevents direct contact between nozzle and weld pool. Heat-resistant and wear-resistant copper alloys ensure consistently stable wire guidance even under high loads.
Available as standard version or custom-made based on your drawings or samples. Geometry, interfaces and material are precisely matched to your requirements.

Material Selection
The copper-beryllium-cobalt alloy reaches a hardness of over 200 HV and offers pronounced compressive strength. It resists plastic deformation under high mechanical loads, short cycle times, and localized surface pressure. Suitable for high-frequency applications with intense loading and elevated surface pressure where conventional materials fail.
The nickel-silicon-chromium alloy offers high thermal strength and mechanical stability. It maintains its shape even at temperatures above 300 °C and shows minimal embrittlement. Suitable for medium duty applications exposed to cyclic thermal and mechanical stress.
The copper-chromium-zirconium alloy is characterized by low recrystallization sensitivity and retains its shape even under prolonged thermal exposure. With a hardness of up to 185 HV, high electrical conductivity, and efficient heat dissipation, it provides reliable wear resistance. Suitable for applications with constant thermal load and strict dimensional stability requirements.

Fundamentals
Function of Contact Tips in Submerged Arc Welding
The contact tip guides the wire electrode into the joint area. Beneath the flux layer, the arc burns between the wire tip and the workpiece. The wire melts and fuses metallurgically with the base material. The surrounding flux and the slag that forms during melting stabilize the process thermally, reduce heat radiation and protect against atmospheric contamination.
The contact tip also defines the wire's entry point and orientation within the joint. This positioning significantly influences how the arc forms the weld pool, the depth of penetration achieved and the resulting bead width and alignment.
Key Parameters of Contact Tips
At the current transfer point, the contact tip is exposed to high thermal loads. The material must conduct heat efficiently to prevent overheating. Alloys with high electrical and thermal conductivity reduce the risk of wire sticking, deformation and process instability.
Friction, heat and mechanical stress gradually wear down the bore. Over time, the inner geometry changes, contact quality degrades and the wire feed becomes uneven. This weakens current transfer and accelerates material wear.
The bore diameter must match the wire precisely. If it's too large, the wire loses secure contact, resistance increases and the arc becomes unstable, leading to inconsistent weld quality. If the bore is too tight, wire feed friction increases, causing jams and accelerated wear on both wire and tip. A correctly toleranced bore ensures smooth feed and stable operation.
The tip keeps the wire aligned with the weld axis. Even small misalignments shift the arc laterally and alter the weld bead. Precise centering prevents oscillation and tilting, keeping the process stable and error-free.
Current flows through the contact area between wire and bore. Surface roughness or deposits increase resistance, disrupt feed consistency and destabilize the arc. A clean, smooth surface ensures reliable current transfer and accurate wire feed.
