strength question!

admin

So at my place of work, we built competition oil pans.  When welding all the baffles and trays and crank scrapers to the inside of the pan, you are required to weld the pieces of sheet metal together, TIG weld, mind you, without any bleed through.  I was wondering how much weeker is a weld with no bleed through, but still some penetration, as opposed to a weld with some bleed through, as in the the welds used to seal the outside of the oil pan shut?  no real reason for this question, just curious lol

Reply:thanks paul!  i most def will play around with that...i generally try to focus on a small bead just for asthetic reasons, since like you said there really isnt much force other than sloshing oil and the weight of the oil on the pans, but im still curious about it haha
