Welding Ceramics  Manufacturers, Traders, Suppliers

Since years ceramic welding nozzles, pins, rollers for the high frequency welding of tubes, and ceramic backing materials for one-sided welding are established in the welding technique.
The pins made from zirconia or silicon nitride exhibit very high mechanical strength and fracture toughness.
Ceramic rollers for the high frequency welding of tubes are made of alumina or silicon nitride in dependence on the tube material.
Ceramic backing materials for one-sided welding are produced as:

• Non-assembled ceramic profiles
• Profiles glued on self-adhesive alumina tape
• Profiles mounted on wire

The brazing assemblies uses valveable materials or oxygen-free copper parts with a similar expansion coefficient to the ceramic parts and metallized ceramic parts to achieve sealing between the ceramic and the metal through brazing. The sealing parts can be argon arc welded with stainless steel, thereby Achieve air-tight connection between ceramic parts and metal structural parts.

– Vacuum and controlled atmosphere brazing up to 2200°F
– Resistance heating and induction brazing for rapid, localized heat
– Broad selection of active metal and silver-based filler metals
– Precise joint clearance control (±0.001”)
– Ultra-clean material preparation and handling
– Advanced inspection using scanning acoustic microscopy

Welding ceramic parts are specialized components made from advanced ceramics such as alumina and zirconia, designed to withstand the extreme conditions of welding processes. These parts provide excellent heat resistance, electrical insulation, and wear resistance, ensuring durability and efficiency.
Common welding ceramic parts include welding nozzles, pins, and shields, which protect equipment and enhance precision during welding. Their non-conductive and thermal shock-resistant properties enable stable performance in high-temperature environments.

Applications of Welding Ceramic Parts
Welding ceramic parts are essential in various welding processes, offering heat resistance, electrical insulation, and precision. Common applications include:
1. Welding Nozzles
Direct shielding gases during TIG and MIG welding to ensure clean and precise welds.
2. Welding Pins
Align and hold metal components in position during spot or resistance welding.
3. Welding Shields
Protect equipment and operators from sparks, heat, and spatter during welding.
4. Insulation Components
Prevent electrical conduction in high-frequency welding equipment.
5. Backing Strips
Support weld pools and ensure smooth weld formation in processes like butt welding.
