While everyone strives for high-quality welds, sometimes the pursuit of perfection can backfire, leading to unnecessary costs and even new defects. This article examines four common scenarios where an excess of quality can be detrimental to your welding operation. From overwelding and the myth that "bigger is better," to the risks of chasing excessive penetration and choosing an overly aesthetic process like TIG for every job, these practices often waste time and money without improving the final product. We also explore why using an undermatching filler metal can sometimes be a smarter, more cost-effective choice for preventing cracks than a high-strength, matching filler. The key is to meet the required quality standards without going beyond what the application demands.
