Maklumat Keselamatan
WARNING: Welding can be hazardous. Protect yourself and others. Read and understand this safety information before operating.
- Renjatan Elektrik Boleh Membunuh: Do not touch live electrical parts. Wear dry welding gloves and protective clothing. Ensure your work area is dry.
- Asap dan Gas Boleh Berbahaya: Jauhkan kepala anda daripada asap. Gunakan pengudaraan atau ekzos untuk mengeluarkan asap dari zon pernafasan.
- Sinar Arka Boleh Membakar Mata dan Kulit: Wear a welding helmet with a proper shade filter. Wear protective clothing to cover all exposed skin.
- Bahaya Kebakaran dan Letupan: Remove all flammable materials from the welding area. Have a fire extinguisher readily available.
- Bahagian Panas Boleh Menyebabkan Melecur Teruk: Allow welded materials to cool before handling. Use insulated gloves and tongs.
- Bunyi Bising Boleh Merosakkan Pendengaran: Pakai pelindung telinga jika tahap bunyi bising tinggi.
- Always use appropriate personal protective equipment (PPE) termasuk topi keledar kimpalan, sarung tangan, pakaian pelindung dan kasut keselamatan.
Penerangan Produk
The Sealey WEHF5032 Hardfacing Welding Electrodes are designed for applications requiring resistance to wear from minerals, medium shocks, and compression. These electrodes provide excellent corrosion protection and are ideal for building up surfaces on components such as blades, spades, and shovel buckets used in agricultural and construction machinery.
These electrodes are versatile and can be used with both AC (Alternating Current) and DC (Direct Current) welding power sources. The specific variant, Ø3.2mm, is recommended for use with a welding current of 130 Amperes.
This image displays the Sealey WEHF5032 Hardfacing Welding Electrodes. The electrodes are gray rods, approximately 3.2mm in diameter and 350mm long, bundled together and partially stored within a bright yellow rectangular plastic case. The case has a label on top indicating 'SEALEY', 'Ø3.2 X 350MM HARDFACING WELDING ELECTRODES 5KG PACK', and 'Model No. WEHF5032'. Some electrodes are shown outside the case, illustrating their length and appearance.

Persediaan dan Penyediaan
- Kawasan Kerja: Ensure the welding area is clean, well-ventilated, and free from flammable materials.
- Sumber Kuasa: Connect your welding machine to a suitable power supply. Verify that the machine is set to the correct current type (AC or DC) and polarity for hardfacing applications.
- Electrode Holder: Securely insert the WEHF5032 electrode into the electrode holder. Ensure good electrical contact.
- Tanah Clamp: Pasang tanah tanahamp firmly to the workpiece or a clean, bare metal surface connected to the workpiece. A good ground connection is crucial for stable arc.
- Penyediaan bahan kerja: Clean the surface to be hardfaced thoroughly. Remove any rust, paint, oil, or other contaminants that could affect weld quality. Preheating may be necessary for certain base metals or thick sections; consult welding guidelines for your specific material.
- PPE: Always wear all required Personal Protective Equipment (PPE) before starting any welding operation.
Arahan Operasi
- Tetapan Semasa: Set your welding machine to the recommended current of 130 Amperes for the Ø3.2mm electrode. Adjust slightly as needed based on arc stability and desired penetration.
- Arc Striking: Strike the arc by either scratching the electrode against the workpiece like a match or by tapping it quickly. Once the arc is established, maintain a consistent arc length.
- Teknik Kimpalan: Maintain a consistent travel speed and electrode angle. For hardfacing, a slight weaving motion or stringer beads can be used depending on the desired coverage and layer thickness. Overlap beads by approximately 30-50% to ensure full coverage.
- Layer Application: For multi-layer hardfacing, allow each layer to cool sufficiently before applying the next to prevent excessive heat buildup and potential cracking.
- Pembuangan sanga: After completing a weld pass, allow the weld to cool slightly, then chip off the slag using a chipping hammer and wire brush. Ensure all slag is removed before depositing subsequent layers.
- Post-Weld Cooling: Allow the hardfaced component to cool slowly in still air to minimize residual stresses.
Penyelenggaraan
- Storan: Store electrodes in a dry, cool place, preferably in their original sealed packaging or a heated electrode oven, to prevent moisture absorption. Moisture can lead to porosity and poor weld quality.
- Pengendalian: Handle electrodes carefully to avoid damaging the flux coating.
- Pemeriksaan: Before use, inspect electrodes for any damage to the flux coating or core wire. Discard damaged electrodes.
Menyelesaikan masalah
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Unstable Arc / Difficulty Striking Arc | Incorrect current setting, poor ground connection, damp electrodes, improper arc length. | Adjust current, ensure good ground, dry electrodes (if applicable), maintain proper arc length. |
| Percikan Berlebihan | Too high current, long arc, incorrect electrode angle. | Reduce current, shorten arc, adjust electrode angle. |
| Porosity (holes in weld) | Damp electrodes, contaminated workpiece, insufficient shielding from arc. | Dry electrodes, clean workpiece thoroughly, ensure proper arc length and technique. |
| Poor Slag Removal | Incorrect current, improper travel speed, wrong electrode angle. | Adjust current, optimize travel speed, correct electrode angle. |
