That's the right way to do it.

Now the welds above are a bit diffrent in that they're a "full penetration" weld. Meaning the members to be joined are welded homogeneously throughout 100% of the joint thickness. This odviously takes more than one pass.

So to answer you'd specific questions the answers are yes.
Gotcha.

Let me ask you from a different perspective - how would one do a multi-pass incorrectly? What are the signs of a poor multi-pass?

Thanks in advance.

1) Should you run the first and subsequent beads at the same power/speed?
2) Is there a geographic strategy to where you lay the initial and subsequent beads?
3) etc.

My interest in this topic is primarily for strength, not aesthetics.

Thanks.

Here's a multiple pass fillet weld...

Plates tacked together...



Root pass...





First pass (bead) of the second layer...note how it overlaps the root pass by about 50%...



Here, I've skipped ahead. This shows the completed 2-pass second layer, and the completed 3-pass third layer. Of course, I've staggered the craters so that you can see the bead sequence. The beads all overlap the previous bead by about 50%. This is known as a "toe-to-crown" technique.







This size weld is way overkill for the thickness of this material, but hopefully, you get the idea of how it's done.

That depends 100% on the individual behind the torch my friend!

For the record those welds are with a Miller synchrowave 250ds.
I may have worded that bad. what I was getting at was your welds were tig and the one on the posts after were mig. And a mig wont make a weld that looks like your welds. I was not trying say your welding was bad. Just wanted the new welders to know how inportant penitration is.

Visually

Uneven weld profile, rolled passes, undercut of the top leg and voids between pass tie in.

RT or UT

Inclusions, porosity and cracking

When making large welds you also have to preheat to the specified temp and manage you heat input so as to not exceed the maximum interpass temperature (most often 450)

I cannot thank you enough for those pics. If you did them just for me, I def owe you a six pack.

Ok....here's one more and I think it may be most important question:

When do you know when you need to double pass? Do you only go by the guidelines in the welder manual or are there other clues/facets that provide the answer?

I multi pass any joint that is critical and thicker than 1/8th....like here the tongue/keel of my trailers join the chassis. But I do this out of being paranoid more than anything else. My single passes have very good penetration but I multi anyway.

So, when do you know when to multi?

I was wondering the same thing. By the ball point pen in the first pic it is something very small. Lots of talent to make welds on that scale look good!
