Tips for Using Welding Wire for Stronger, Less Porous Connections

Welding is a crucial process in construction, especially when joining steel and iron materials. One of the most common problems is porosity, the appearance of small holes in the welded joint, making the result weak and prone to cracking. This can be caused by improper technique, material condition, or the type of welding wire used.

To ensure a stronger, neater, and porous-free weld, here are some important tips to keep in mind.

1. Choose Welding Wire According to Material Type
Each type of iron or steel requires a different type of welding wire.

• Use E6013 welding wire for general work.
• Use E7018 for heavy construction or joints requiring high strength.

The correct choice will create a more solid joint that is less prone to cracking.

2. Ensure Welding Wire is Dry and Free from Moisture
Moisture is a major cause of porosity.
If welding wire absorbs water, the gas will be trapped during the welding process, creating pores.
Store welding wire in a dry place or in a special oven before use, especially for low-hydrogen types like E7018.

3. Clean the Welding Area Before Starting
Dirt, oil, dust, rust, and paint on metal surfaces can cause porosity.
Ensure the material is:

• Sanitized
• Cleaned of oil
• Cleaned of rust

The cleaner the surface, the stronger the weld will be.

4. Set the Welding Current According to Recommendations
Too low a current will result in poor penetration, while too high a current will burn the material and create pores.
Follow the manufacturer's amperage recommendations, usually listed on the welding wire packaging.

5. Keep the Welding Wire Steady
Excessively fast or unstable movements can cause holes and pores.
Aim for:

• Constant hand speed
• Wire angle of 20–30 degrees
• Use an appropriate movement pattern (U, O, or light zigzag)

6. Avoid Welding in Windy Areas
Wind can remove the shielding gas, resulting in a porous weld. If welding outdoors, use a cover or windscreen to maintain the quality of the joint.

7. Use Quality Welding Wire
Low-quality welding wire tends to produce a lot of spatter and spatter.
Choose welding wire from a trusted supplier to ensure the stability and strength of the weld.

Conclusion
To achieve a strong, porous, and durable weld joint, it is important to pay attention to welding wire selection, material cleanliness, technical stability, and proper current settings. With the correct technique and quality materials, the welding process will produce optimal joints for various construction needs.
