Hi guys, just joined the forum because I'm in need of some urgent advice. Having some building work done which involves a steel goal post for some bifold doors. The beam is a 6m long box section (200x100x10mm) which connects to the posts which are 150x100x5mm. A 80x160mm box section was welded to the posts and the large box section slots into that, and originally hollo bolts were going to be used to connect the 2 steels together. However, the decision was made to weld it onsite instead with a section removed from the bottom so it can be slotted in from abov e and then welded afterwards. Now the builder has been good otherwise on all aspects of the build, but on this part he brought in a welder which I think clearly lacks experience. I was hoping for some confirmation that the welding done is not up to standard. Please see attached pictures. I have a little knowledge of welding, and the welds look absolutely terrible. He used a small arc welder, didn't clean the metal before welding. He didn't even bother knocking off the slag, so i did and it looks like there is porosity in the weld bead, it looks inconsistent, it's undercutting in parts, it's definitely not penetrating fully and he hasn't even gone all the way round. I'll attach a few photos to this post, but here is a link to the full set (mods please remove the link if its not allowed): https://drive.google.com/drive/folders/1aYt1LhmVwftcxLeJeQKJvC5vMAhuXHDm?usp=sharing Comments welcome, I should get this redone right? It's supposed to be a structural weld! If there are any good welders in the west midlands, please get in touch!
