Hi all. This is my first post although i've been watching jody's videos for a long time.
This is a timing cover out of a 2013 Honda Fit. It was in a frontal crash and the motor mount sheared off the timing cover taking a couple of chunks off of it. The cover is not available from the dealership yet so we had no choice, it had to be fixed.
Basically i had to add the metal that was missing, drill a new hole for the motor mount stud and make it look somewhat decent.
I think it came out pretty good. I used a Hobart EZtig 165.

rodrigoziminov,

Welcome aboard!

That's impressive work, especially if the "165" in the welder's name is it's peak amperage. Did you pre-heat? Include a helium/argon mix? And if I missed it, what alloy filler did you use?

That's the kind of practical knowledge this forum is all about...

Welcome
You did a good repair. I did a similar repair on a Volvo engine block a while ago so I know the effort it takes to do it under 200 amps.

On pic 6 it looks like it didnt melt thru. Hope it wont take any load cus that gives massive stress concentration.
I barely could get a 9 torch in and had difficulties getting the arc at bottom of V-groove. Had to grind down and re weld coupple of times to melt thru. Drilled out and heli coiled when I wad happy with the weld.

As far as load goes it is overkill anyway. Ive seen these engines held together by 1 bolt and not have any problems.
I used no preheat. Basically what i do is hit it first with no filler wire trying to get the AC to clean the casting a bit. By the time you are done "cleaning" it is pretty hot and you can start adding filler. It is a pain though. You have to stop and wirebrush constantly. I think i used 4043 filler with straight argon.
