nope not really. I tell em its smart welding doors now and then cuz it might make good camping spots, but try not to make "deathtraps" and sometimes I tell them they should find a camping spots (then I suddenly dissapear because its a "deathtrap" xD)
Please remember that as level 6 support you have significant welding bonus too. So you can hold the door welded alone while there should be at least two level 3-4 support to do this job on later waves.
And I "believe" you that you are doing only the welding job. And when double fleshpounds comes and kills every teammate, you just let them to kill you, not solo-end the wave
