The tank will warm up quite quickly, hold it there for several minutes it will then be totally safe to weld/ have welded. tell the welder what you have done to the tank.

January 12, 201115 yr I have played around with durafix type products without too much sucess. I think your best approach would be to recess the split slightly and fill the recess with the filler rod after thorough cleaning. Note all the videos show horizontal repairs where the filler rod is puddled in. if you try anything vertical the filler runs away! I would also be looking to see why the tank split in the first place. Is it mounted properly ? My experience with durafix type products is that it tends to crack especially if subject to vibration. my recommendation would be to have it tig welded, if the durafix type stuff doesn't work i think you willl struggle to tig weld it afterwards.
