For weldability ranges please contact us with the material and cross-section surface area. ****Weldability - Stranded Cables/Ropes/Cords Butt Welding using Glass Sleeves, Ceramic Sleeves or Carbon Sleeves which function as crucibles during the Stranded Cable Butt Welding Application- For weldability ranges please contact us with the material and cross-section surface area. Electroweld Ceramic Sleeves for Stranded Cable Cross Section : 0.16 mm² - 193 mm² Applications: Electroweld Ceramic Sleeves are designed for butt welding of stranded conductors. Example: For enabling continuous wire drawing manufacturing operations, the two ends of the stranded conductor to be welded are inserted into the Ceramic Sleeve openings on each end, such that they meet in the middle of the tube. This assembly of the stranded cables and ceramic sleeve is then clamped into the jaws of the matching Electroweld Butt Welding machine. When the butt welding process is initiated, the ceramic sleeve act as a crucible and the ends of the stranded conductors inside the sleeve fuse to form a burr free and pore free weld. The ceramic sleeve is then broken with a hammer or mallet revealing the butt welded stranded cable which can then be processed upstream, ensuring continuous operations of the wire drawing manufacturing process. Note: The Welding Jaw Clamping mechanism on Electroweld Butt Welding Machines is either Hand Operated, Foot Operated or Pneumatic Cylinder Operated, depending on the stranded conductor being welded and the corresponding matching machine rating. Regarding Upset Pressure mechanism in Electroweld Butt Welding Machines- For smaller cross-section stranded conductors, the butt welding upset pressure is applied via spring tension and for larger cross-section stranded conductors, the butt welding upset pressure is applied via pneumatic cylinders. Additionally the clamping pressure should be approximately twice the upset butt welding pressure to avoid slippage and turning of the stranded conductors inside the sleeve during butt welding. Unique Characteristics of Ceramic Sleeves for Butt Welding Application: 1. Very high compressive strength. 2. Moderate to extremely high mechanical strength. 3. Moderate thermal conductivity 4. High thermal shock resistance. 5. High thermal Stability and operating temperatures. 6. Low co-efficient of thermal expansion. 7. Electrical insulation. 8. Easily and readily machinable. 9. High Hardness, High wear and Friction resistance. 10. Corrosion resistance even at high temperatures. 11. Low Specific Weight. Ordering and Lead Times for Delivery : Note: MINIMUM ORDER QUANTITY (MOQ) FOR CERAMIC SLEEVES IN ANY PARTICULAR DIMENSION- 1000 Qty. Minimum 4-5 Weeks Lead time for Delivery of MOQ. Samples could be made available earlier on request.

If the clearance is too large, the axial rigidity of the strand is reduced and the wires begin to fold in the sleeve. The sleeve size must be considered as one would consider the size of a welding die. It must not stop the conductor from being introduced, but some friction needs to exist. Additionally, the choice of a good cutter is an important step towards a successful weld. If we advise our users to do not over-strand the conductor after cutting, it is also for this reason. As the manual over-stranding is never regular, it changes not only the quality of sliding in the sleeve, but also the clearance and all the other parameters. Furthermore, another negative consequence of a larger diameter weld is the risk of being broken or drawn when it later goes through the insulation head. Note 2: Using Right Tool for Cutting Stranded Conductor before introduction into the Ceramic Sleeve for Butt Welding : The users often cut the conductors with scissors. Even if it is difficult to see, this increases the conductors length and let a flat burr outside the strand. Furthermore, the conductor un-strands easily and the user tries to over-strand it to keep it again rigid. As a result, he must then use a sleeve larger than necessary and this increases the clearance between the sleeve and the conductor. Another negative consequence of this over-stranding is the lay-length decrease which decreases the flowing of the melted metal between the wires. The operator must then increase the upset to compensate for the larger clearance but cannot increase the pressure because the conductor is less well driven in the sleeve during the fusion. As the welding is not satisfactory, the operator then requires longer sleeves, hoping to correct the problem. The weld then becomes longer and breaks easily after several folding in the accumulator further down the line. In fact, a good driving in the sleeve requires as little as possible clearance between the sleeve and the conductor. Following are some examples: cross sections clearance 0.25 to 0.35 mm² 0.03 to 0.05 mm 1.5 to 4 mm² 0.5 to 0.7 mm Note 3: Slipping the conductor in the sleeve : We also suggest that the operator creates a small cone at the inlet of the sleeve to ease the strand introduction, and avoid any irregular over-stranding. Note 4: Clamping of the conductor in the jaws : When the conductor folds during the fusion, the reason is often a bad clamping in the jaws. When the pressure is applied, badly clamped conductors slice in the jaws and the weld turns around those ones which are correctly clamped. Theoretically, the best shape for the jaws is a circular groove but practically, we advice to use 'U' grooves because the setting and the clamping is more reliable. Specifications for Sillimanite used for making the Ceramic Sleeves : Note: These Ceramic Sleeves are made with Sillimanite and other minerals. They mainly consists of Al2O3 and SiO2. Their physical and chemical properties are better than high grade Alumina Ceramics. Their max use temperature is 1600 ℃.

Butt-welding is a technique where two metal ends are connected with no overlap, forming a near seamless merger. To do so, the two ends are heated by passing an electric current through the weld interface. The interface causes heating due to resistance to the current. Heating continues until the metal reaches a plastic-like state. The ends (or butts) are then pressed together, where they form a knot or upset. The knot or upset is then ground down to a smooth finish. This technique is great for creating closed-loop steel rings or welding rods. Butt-welding is sometimes used interchangeably with Upset Welding. As we can see both of them are the exact same process with just a difference in the name.
