Mig build-up (vertical-up)

[vicegrip]

Huge gearcase (probably for a drag-line) had all-ready been welded in several areas , that would not clean-up [machine-ing to size]....

found that some of it still needed aditional build-up ......
a great deal of this is done out of position...if the part is allready set-up on a machine !

these welders use several different methods , and lap layers in there own way....
I have no say , and my input would be obnoxcious...

This time they sent over a young fellow ...nov. 05 was his first job out of welding school...
So he actually asked what I was looking for ......I showed him how much build-up I was looking for and where....

he gave me vert-up bands about an 1inch wide side by side , and aditional layers were offset sideways at half the width......did an awsome job and the interactive discusion cheared me up after a very discourageing few days of other dealings...

I have never used mig for build-up on any scale.....and I asked for advice ....and comended his work...

further : when machine-ing with carbide inserts the burnishing effect shows up differeences in the HAZ and even between the core of every beed and the juction of the beeds to each other...his was a fingerprint of vary consistant result ... a tad of print at the HAZ and virtually nothing bead to bead...

I was disapointed no-one had even a camera-phone.....and suddenly realised that some of the skale/slag had not been stepped on and took it home for pics.....

I hope I get this young craftsman for my next build-up !!
