Endeavour - quality controlled aluminium MIG/GMAW welds
Production run of 3-gusset-plate right-angle-bracket machine parts.
Qualitative judgement, "Trade" skills and intuition are vital in
Apply those, and possess good quantitative measured information about your welding process, is "a winning formula".

A very important topic : Weld Quality Control
The ups and downs experienced by a welder : welding tales
This was a big endeavour for me. I attended vocational welding courses over a five year period.
Welding process training - oxy-acetylene, SMA, TIG, MIG and a bit of pipe-welding.
TIG welding: feeding filler wire - technique for manual TIG welding (has movies).
Note this is continuously feeding filler for sheet-metal thicknesses - not the cyclic "stack of dimes" method used for large TIG welds.
My first ever macro-etch of an aluminium weld. Using "household" supplies and "kitchen" equipment.
Tensile-test rig for fillet-welds (more detail - see "Structures" index )
Welding equipment I have used.
Mixed miscellaneous stuff on welding.
If you weld, you often also want to oxy-acetylene cut. So here is the
method I use to
set an oxy-cutting torch.
It does not use pressure gauge readings.
The article starts with methods to mark out "black" steel - steel as-rolled with oxide on surface. Using soapstone, rules and squares.
Is the current "preferred" approach to weld metallurgical qualification, ISO15614, continuing to work well? Is it time for a re-think? Here is an alternative new proposal taking the currently less-used very-restricted-application ISO15610 approach and making the ISO15610 approach the new preference for most welding fabrication.
