Attention & Precautions
- Electrode must be approved by 350-380℃ for 1 hour before welding, dry the electrode when use it.
- The rust, oil, water and other impurities of the weld must be removed before welding.
- You must use short arc welding, the swings should not be too large, narrow bead welding is appropriate.
- To prevent producing arc porosity, arc plate should be adopted or use return method for arc welding.

Process Technical Requirements
- Important welding parts should be clearly marked in accordance with relevant regulations when preparing welding procedure specifications.
- Assembling the mold (assembly fixture) of the welded parts, the amount of welding shrinkage must be considered to ensure design tolerances.
- Before assembling, remove the rust, oil, dust and moisture within no less than 25mm on both sides of the weld.
- The assembly gap should be controlled: butt welds 2~3mm, fillet welds 0~2mm. Filling gaps with unauthorized fillers is strictly forbidden.
- Welding materials and process parameters used in assembly tack welding shall be the same as formal weld requirements.
- For new materials and processes, process tests must be qualified before use.
- The welding slag and defects at the root of the weld must be removed before welding reverse or grooved welds.
- It is forbidden to start arc ignition and test current adjustment in non-welding areas.
- For steel plates with a thickness of 0.3~4mm, gas metal arc welding or argon tungsten arc welding are recommended.
- During multi-layer welding, joints between layers should be staggered and temperature controlled between 250~300℃.
Frequently Asked Questions
Q1: What are the main applications of E6013 welding powder?
E6013 powder is primarily used for making carbon steel welding electrodes. It features a titania type coating, supports all-position welding, and is compatible with both AC and DC power sources.
Q2: Do I need to pre-treat the electrodes before welding?
Yes, electrodes should be baked at 350-380℃ for approximately 1 hour to ensure they are dry before use, which helps in achieving optimal welding performance.
Q3: How should I manage the assembly gap for butt welds?
For butt welds, the assembly gap should be strictly controlled between 2~3mm. For fillet welds, the gap should be kept between 0~2mm to avoid residual stress.
Q4: What is the recommended inter-layer temperature for multi-layer welding?
During multi-layer welding, especially with low-alloy structural steel, the temperature between layers should be maintained between 250~300℃.
Q5: What are the aesthetic benefits of using E6013 electrodes?
E6013 electrodes provide a very stable arc, minimal spatter, and easy slag removal, resulting in a smooth, shiny, and professional welding appearance.
