Welding is part skill and part science, and the type of weld an individual fabricator lays fuse often comes down to what kind of welding wire ลวดเชื่อม they use. Production faults through the weld assembly weaken the weldment and may result in expensive service, or ultimately catastrophic failure. At Udo. At welding Thailand, co.th, we consider top-quality welds a priority and, so we’re here to assist you to get rid of typical welding wire flaws and get the best possible results.
Understanding Common Welding Wire Defects
- But before we get into how to prevent these issues, let’s have a look at some of the most typical welding wire defects that you may come across:
- Porosity – this is seen as uniform small holes or voids within the weld which can often be from any gasses that are trapped during the welding.
- Undercut: A groove or notch that occurs at the edge of the weld may be caused by too much heat or an improper technique.
- Spatter – Small molten metal droplets from the weld pool that are expelled and solidify on the surrounding material
- Incomplete Penetration: This happens when the weld metal does not penetrate the base metal well enough, making for a weak bondLack of Fusion: This is when the weld metal does not fuse with the base metal at all, creating a weak joint
- This condition can occur both in the weld metal and in the heat-affected zone and can have a deleterious effect on the strength of the joint.
Preventing Welding Wire Defects: Tips and Techniques
- Fortunately, a lot of these defects can be avoided with the right care and attention to detail during the production process of a welding wire. Top 5 Tips To Improve Weld Quality
- Proper Welding Wire Selection : Making the same mistake of shore welding wire consumables to your exact process and base metal is a must. Always check with the manufacturer or consult with an expert to make sure that you are using the right type of wire for the application. Udo.

- Keep It Clean: Clean the base metal that will be welded to ensure it is free of dirt, rust, oil or other debris. These contaminants can lower the strength of the weld and produce irregularities.
- A Proper Storage: You need to store your welding wire in a clean and dry situation; that is because the wire will absorb moisture from the air which can cause porosity issues.
- Proper Welding Parameters: Change your welding parameters, i.e. amps, voltage, and travel speed, based on the welding wire and base metal you are welding. Refer to the welding procedure specifications (WPS) for direction.
- Practice: Keeping a steady hand and traveling speed are crucial for weld quality. Keep oscillations small and controlled: the action of over weaving will commit an undercut error and the torch energy affecting the weave, will slow the part cooling and elongate the weld cartesian coordinates, whilst erratic movements will do the same.
- Welding Shielding Gas – Use correct shielding gas for the welding process and materials. Make sure that gas flow rate is sufficient so that the weld pool is saved from atmospheric contamination.
- Preheat and Post Weld Heat Treatment (PWHT): Preheating the component and doing a PWHT post welding can lower the risks of cracking based on the Base metal and welding process.
