1. Drying Requirements: Low-hydrogen electrodes require strict baking before use. Bake at 300–350°C for 1–2 hours. After baking, store in a drying oven at 100–150°C. Electrodes exposed to air for more than 4 hours must be re-baked (limited to once).
2. Welding Technique: Use short arc operation during welding; narrow weld beads are preferred to minimize hydrogen absorption and ensure proper weld quality.
3. Base Metal Preparation: Remove oil, rust, moisture, and other contaminants from the welding area to prevent hydrogen-induced cracking.
4. Preheating: For carbon steel, preheating is generally not required. For thick plates, high-strength steels, or low-temperature environments, preheating at 50–100°C is recommended.
