Done 7th week of weldign job.  It seems to be settling-down.  My
repertoire of customers is very limited, but I am refining my welding
technique and getting more efficient hence quicker.

I've had some "golden hints" - eg. for an outside-corner MIG / GMAW
joint in the horizontal-vertical position, a weave is needed bacause it
will not run stable otherwise (familiar other one is horizontal-vertical
T-fillet weld with 6010 cellulosic stick - sometimes will not run stable
"straight-run" and needs a "whipping" manipulation).  I only needed to
see it for one second for "the penny to drop".
Others similar-ish.  So, has been good.

I have contributed - this has started to happen.  I used "the bubble"
(spirit-level) on some fabrications, and found that what it cost in time
to set things off parallel at the first stage was more than made-up for
by the "ideal" time it took to fit-up and weld the rest.
Show the approach and the corrections, the owner and designer where on
the press-brake with dial-gauges, etc., and made adjustments.
ie. there is something positive going on.

Etc.

It is hard work getting back to it, for sure.

I have developed muscles to "float the torch" (GMAW "gun").
While having a guide can give the most "exhibition grade" welds,
practically for production "floating the torch" has you quickly moving
along the welds presented in-line on your trestles.
It is good keeping a consistent weld when the "harness" (tube for the
wire, gas, control-cables, etc.) has found something to drag on mid-run
and you continue to do an invariant run.  Etc.

Best wishes
