Knowledge Guide: What Happens to a Bolt When You Weld on It?
Though weld on bolts is never the ideal solution in the world of engineering, sometimes, this may be necessary. When you weld bolt stuff, does this weaken the bolt? What happens to a bolt when it is welded?
It pertains to the process of securely attaching bolts, studs, or fasteners to a metal workpieces.
This technique is usually faster and efficient, more than drilling and tapping, but there are also downsides. Learn everything about this topic in this discussion that will tackle the following:

– Using fasteners is better than welding

What Happens to Bolts When Welding Them?
Basically, right here and right now, you should know the welding heat-treated bolts will weaken the bolt simply since this tends to heat the bolt beyond its tempering point or range.
Thus, when you wish to weld a bolt in any given situation, you must be fully aware of the properties of the material you are dealing with beforehand. Applying heat to a pre-treated bolt alters its strength.
More so, each time you apply heat to a pre-treated bolt, you will also be altering its strength. On the other hand, if a tempered bolt is applied with heat in an uncontrolled, random environment, you get varying outcomes.

More DetailsHow About Overheating Bolts?
Some tend to overheat a hardened steel bolt, but this habit will soften the bolt if the temperature is too high or if the weld bolt is exposed to the heat for such a long time. However, remember that at the end of the day, heating the bolt in uncontrolled environments will always weaken it.
Is It Possible to Weld a High-Strength Anchoring Bolt or Fastener?
The rule of thumb here is that putting a high-strength weld on bolts is not permitted. During the manufacturing of such bolts, it already goes through a permitted specific heating process to reach its ideal strength. If you reheat or place weld on bolts, this compromises their structure. Hence, it must be made clear that this is never recommended.
During the manufacturing process, high-strength bolts are heat-treated to protect them against the intense tension and sheer force from specific loads. However, note that heat treatment processes differ to achieve specific outcomes. Some processes harden the bolt, while others tend to soften it.

More DetailsRecommendations
Overall, even if you have a bolt that is weldable, putting weld on bolts or to tack weld nut materials should be a well-thought-out process. It is highly recommended that you consult experts, especially what you are dealing with are sensitive processes for welded nuts and bolts.
At the end of the day, another recommendation is to use fasteners than welding. They are lower in costs, provide equal strength as welding, are more accurate, and are easier to finish and replace.
