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 !!

Whenever I do work for our machinists I always ask what they want and the mininum amount they require, they have to machine it so I figure it should be done how they want it if possible. To many welders have attitudes and figure they know more because they are doing the welding and not the machining. Its nice to have a guy who asks what you want, our machinists always ask us about weld preps.

Sounds like this fellow*** and you are cut out of the same fine fabric !

>>>nothing here is too refect on any other welders at my currant employment....as I have had little or no contact with the majority of them so far .......but more with my accumulative experience over the years....machinists and even more-so tool-makers certainly can have atitudes as well about anything that needs one...

Vicegrip I was working on a conveyor belt onetime doing assembly and was having a few problems when a millwright happens by and asks if I would like some help. I told him I could really use the help as some of the work required was new to me and I did'nt have a clue what to do next. I just floored the guy, he told me most people would rather struggle than ask for help and when offered seemed to get pissed off, I learned a lot that day.

Ya some machinist have quite an attitude also. Why I could'nt tell you, maybe to proud to admit they don't know something?

[vicegrip]

I didn't want anything to do with toolmaking when first given the oportunity , for that reason , didn't want to become an opinionated boore ...

after this long I think I understand the process.....your work will come out the best if you KNOW for SURE , every detail about what you are doing , tram, squareness, wear on the machine or not , the nature of the matrial , the use of the Item to be made ,

After decades of KNOWING EVERYTHING , it spills over to regions of your life where it OUGHT NOT to have
