Sometimes welding can look a bit flimsy but is done as required.
In the 80s i did a bit of top-fuel motorbike racing and i had a frame made by a famous dutch framebuilder Nico Bakker
http://www.bakker-framebouw.nl/who did build a lightweight frame made from chromoly.
All the tubes were different sizes and it looked as they were only tag-welded,when i asked if i had to finish the welds myself Nico laughed and told me this was stronger as a full weld mainley because there was less heatheffected zones in the metal.
The different sizes of the tubes were to reduce weight,only as strong as was needed on a particular place was used,not only the outside diameter but also wall thickness was different.
I used this frame for 8 years including 3 crashes and sold it when i stopped racing,after this it was used for 5 years more and still exists in a private collection..
Only telling this to show if you think it's bad it don't have to be bad
