I'll bet you a dollar your machines are also running dual shield and very large electrode size. About the only part of that which translates over to what we do is how to know when you are looking at a quality weld and what to change when it isn't.i try not to get into others welding,
(but dammit the weld looks cold to me and i'd hate to see you have 1 fail on you)
i run a huge robotic gantry welder and 2 smaller traversing units.
i will say i'm dictated by how and what my machines can reach, and am responsible for quality welds, regardless of conditions. this is production welding and has to be correct in 1 pass. (there are instances where multi-pass welds are required on large drive bases up to 7000#)
my welds are tested frequently.
each weld in my programs is controlled and each weld condition requires different voltages and wire speeds as well as weave or not. and can have as many as 600 individually programmed movements to complete a sequence.
the machines are capable of a weave amplitude of over an inch, as well as having several weave patterns at a dictated frequency.
i saw a post not long ago about the robots welds from the factory on the newer Jeeps............made my laugh.
you cannot tell/teach a programmer how to weld. and they are running out of welders to teach how to program.
