Why are my welds flat?
Adjust the parameters to a lower setting so the weld pool is less fluid and more able to fill in the joint. If a concave weld bead appears in the flat or horizontal position, it’s often the result of voltage that’s too high, wire feed speed that is too slow or travel speed that is too fast.
What is grind flush?
Flush-grinding of a butt weld is an established method for improving its fatigue performance. This eliminates the stress concentration created by the weld profile and removes the inherent weld toe flaws at which fatigue cracks typically initiate.
How do you smooth out grinded metal?
Sand the part with progressively finer sandpaper, working from 40-grit down to 320-grit. Once finished with 320-grit sandpaper, the grind marks should be completely removed. If a polished surface is desired use 600-grit sandpaper and water to remove the very fine scratches left by the 320-grit.

How do you clean a weld?
Wire brushes and wheels are a good option for interpass or post-weld cleaning, when it is necessary to remove spatter and other contaminants. If the material has a lot of mill scale, rust or heat discoloration to remove (without removing a lot of material), wire brushes also work well for pre-cleaning.
Why are my welds cracking?
Cracking can be caused by many different problems from rapid cooling to contamination. But in almost all cases, the reason cracking occurs is because the internal stresses exceed either your weld, your base metal or both. After you weld, both your base metal and your weld begin shirking as they cool.
Should you weld both sides?

How do I know if my weld is strong?
To really test a weld you need to do a x-ray test, magnaflux test, dye penetrant test or ultrasonic test which looks for voids, lack of fusion, etc.
Why do my welds look like popcorn?
A weld may look like popcorn when the wire is speeding too fast or slow or when the fire feeding happens before the melting. If you use solid wire without shielding gas, you might also hear popping sounds. Other reasons may include the wire’s incorrect size, amperage adjustments and voltage.
