If the surfaces are not clean, free of rust, paint, or other contaminants, it can lead to poor weld penetration and weak bond strength. Another common mistake is improper heat control. If the heat is too low, the weld may not penetrate properly, leading to weak joints. On the other hand, if the heat is too high, it can cause distortion, burn-through, and w...
