No, it won't introduce cracks in the weld, or nearly every small trailer, and cargo trailer manufacturer in this country is in deep doo -doo. Not properly done, it can have issues such as slag entrapment or incomplete fusion, which would cause cracking at the weak points, but you are not "introducing" cracks to the weld necessarily, other than for incomplete fusion.

Thanks for the follow-up, Mark.
