I would use some skin pins so once you have it all lined up then drill a couple of holes and fit pins. Job done plus they wont move around as much as sealant.
With regards to the welding rods weld to the door skin. See this link

Great info again Sonikk were do you keep it all. I'll have to acquire some of these called skin pins then.
Thanks for the link I'll have a study of that over a cuppa at lunch.
