Wild West Showdown Trophy Project

Wild West Showdown.


So far I have started one. This will be a Davinchi Gyroscope theme -

Today 1/30/2013 I spent a few hours driving about gathering gears, bits and, pieces for the trophy projects. after that I met with Chris (the derby dude who gave me the chance to work on these for the kids) to talk about the trophies and what they should be like. He said,"do what you want ."   I like him already. I visited with a friend up north "Nick" who had a few choice parts including the final piece to finish the gyroscope portion of this trophy. All in all A great day for parts gathering !  
After several hours at Olympic College  with help from Tim and Keven a couple of great all aluminum forms were cut using the Plasma Table.
 An exhausted Kevin Snell !



Tim not to thrilled to have his picture taken !

Tim helped with the gyroscope and made auto cad look easy !

The gyroscope pieces are nearly perfect and the boots well, those are some great boots !

6013 SMAW Electrode and Me !

     Yesterday and today I have been in my shop playing with a pile of 6013 3/32 electrode I found while cleaning. I find that it runs great for me in the 1 and 2 F & G positions however, when I switch to 3 & 4 F & G positions I have a great deal of trouble keeping the bead consistent.
 3G Vert Up sure looks good but this is the only set of good welds after 20 passes or so.
 I have 2 different types of flux coatings on the 6013 I have been using one is light grey similar to some 7018's I have worked with, some is dark grey with a black tip and much narrower, the second type seems to run much better up hill - both were ugly for the overhead which I did not photo as it was reaaaallllyyyy UGLY .
 Just like the container says, I have a "mixed blend" of 6013

It is safe to say that I enjoy GTAW much more than SMAW but, this has been a fun couple days of playing with Arc welding and it is likly that I will try to pick up some differing types of electrode in the near future (6010-6011 and some 7018 ect ) to play with.

Happy Welding !

Arc welding for a change .

       So, while cleaning my shop I found some old Arc Welding electrode (3/32 6013) and decided to hook the stinger up and weld on some plate I had laying around the shop just for kicks. I set the machine around 85 amps with a dig setting around 30 put the plate together in a T Joint fashion and sat down to weld. To my surprise the welds looked great and, after a bunch of passes I paused to take a photo for better or worse.
1 F being lazy .

      After taking this photo I decided to let it cool down a bit and put a few more passes in before dinner and the next photo is the end result as I left it.

Still 1 F many passes later .

   I go out to my shop every day and weld for a few hours to stay in practice, for the next few posts I will likely be adding various Arc Welding related things.

Happy Welding !

Aluminum
There are approximately 12 designations for aluminum
filler rods. A common all purpose rod is ER4043. The “ER”
designates electrode or rod, and the “4043” designates a
specific chemical composition. ER4043 is used with many
aluminum base metals, but always consult electrode wire
manufacturers for the proper filler to use in critical welds.



Filler Metal Specifications:

The American Welding Society (AWS) publishes several
booklets of specifications for GTAW filler materials. Often
these booklets are used as specifications for GMAW electrode
wires as well. Figure 4.19 is a list of AWS filler material,
shielding gas and tungsten electrode specification booklets.
Figure 4.19 AWS specifications for GTAW filler materials, shielding gases
and tungsten electrodes.
Types and Designations of
Filler Metals

Steel
There are seven designations for carbon steel filler rods. A
typical designation would be ER70S-6 for TIG. The “ER”
means the filler can be used for either GTAW or GMAW. If the
designation lacked the “R” it would signify a continuous electrode
for use with GMAW only. There is no designation for rod
using just the “R”, it will always be “ER”. The “70” stands for
the welded tensile strength, measured in thousands of
pounds per square inch. “S” stands for “Solid” electrode as
opposed to a tubular or hollow wire such as that used in the
flux cored welding process. And the “6” refers to the particular
degree of manufactured chemical percentages within the rods
composition. In other words, the number at the end of the
description refers to which classification of wire is being used.
Stainless Steels

There are many more stainless steel designations than there
are steel designations. A typical classification of a stainless
rod would be ER308. The “ER”, as it is in steel, stands for either
continuous electrode, or electrode rod. The “308” designates
a specific stainless steel chemical composition. These numbers
are often used to match the filler rod to specific compositions
of base metals being welded.

Certain types of stainless steel rods may have letters or numbers
after the three digits, such as “L” meaning low carbon
content, or “Si” meaning high silicon content. Sometimes a
manufacturer’s brand name may use “ELC” instead of “L” to
mean Extra Low Carbon, or “HiSil” instead of “Si” meaning
High Silicon Content.

It’s important to remember the “ER” designations because
the AWS has separate specification books for “ER” filler metals
and for “E” filler metals. “E” filler metals, such as E308-16,
would refer to covered welding electrodes, such as those
used for SMAW (Stick).

Titanium

There are approximately 13 different designations for titanium
filler rods. A typical designation would be ERTi-5ELI. The
“ER” means the filler can be used for either GTAW or GMAW.
The “Ti” indicates titanium, the “5” is specific characteristics
such as alloy content, and the “ELI” means extra-low interstitial
impurities. If the base metal has extra-low interstitial impurities
the filler metal selected should also carry the same classification. The interstitial nature of elements such as carbon,

hydrogen, oxygen and nitrogen are kept very low with the
ELI classification.

When welding titanium and its alloy, the filler metal should
closely match the alloy content of the base metal being welded.
The ERTi-1, -2, -3 and -4 are designations for commercially
pure titanium (CP) welding. These unalloyed filler metals can
tolerate some contamination from the welding atmosphere
without significant loss in ductility. Unalloyed filler metals
may be used to weld titanium alloys when ductility is more
important than joint strength. Less than 100% joint efficiencies
can be expected.

Welding Symbols and Shop Drawings

Basic Print

      Shop drawings and welding symbols are the core of any welder. Many welders come out of college with little more than a rudimentary understanding of how these work however they are the key to any good welding position.

      In both the welding programs I was enrolled in we used the same book Blueprint Reading for Welders 8th edition. This book is utter garbage and is filled with miss prints and mistakes however the section on weld symbols if fairly inclusive. Being able to understand how a welding symbol works is as important as understanding how a blueprint or shop drawing is laid out.

   Welding symbols are fairly straight forward if not very technical and are often miss printed on a shop drawing. As a welder you must have a grasp on how these are supposed to be laid out on your drawing or print as it is always harder to rework a weld than to do it right the first time. basic shop drawings

   Blue print reading begins with a basic understanding of line types as well as the scale the drawing is in. Some drawing may be simple some may be very complicated this is dependent on the type of job to be preformed.

   A welder uses many differing types of measuring tools depending on the job and the accuracy requirement which can very from + - 1/8th" to + - .001" an understanding of more than a tape measure is a huge help, I carry a scientific calculator and a 6" engineering ruler in my pocket wherever I go. My math is good but a long ways from the best ! I also have many conversion tables on hand in my shop to make my life easier, many time I do not want to do the math the long way and would rather weld.

A friend requested a basic tool list for hand drafting so here it is, a good board/table never hurts either.

Drafting by hand is more of an art form than actual drafting, that is to say with things like AutoCad, Solid Works and such, on the computer making changes and modifications much easier and faster this is more or less out dated technology. I enjoy drafting by hand but, that is purely because I love the way the drawings look and the time it takes. It is like reading to me - very relaxing !

Hobart vegetable slicer attachment repair !

           This was a fairly straight forward repair after I hunted down the right parts to use.

                          I used my normal set up with 3/32 Lanthanated tungsten.

Silica Bronze filler metal was used heavily for the latch !

                           I used tooling and a drill press to achieve the accuracy of the latch
                                It was built  up several times in several places to get it within tolerance  !
The finished latch Fits great and is much stronger than the original !
For the push door I used stainless steel hex head bolts and welded the shaft to them.

This is fusion welded to save the threads , it is a very tight fit !
This is the end product below !                                                    

A perfect fit no play whatsoever !


                      Overall this project went perfectly an I am very happy with the final result !

Happy Welding !

Aluminum Bakery Rack Repair Job !

4 of these aluminum bakery racks came into the shop today for repair thanks to - 
I will be working on them tomorrow pictures will follow ..





This was the setup I used .

This was typical damage .
Some I patched some I built up.
Below is a patch partially cleaned up.
Typical repair on the board racks , there were many of these broken.

I finished the job today using my normal set up which worked much better !
I used a 3/32 1.5% lanthenated  tungsten

Good Weld - Bad Weld - Metallurgy ?

      I have been welding for about 3 years now, 2 of which I have dedicated to learning how to TIG weld. Like most types of welding there is far more to do wrong than right , this thread is dedicated to pictures of both good and bad welds most of which I have found on the web !


                                            The above and below photos are mild steel .



This is chromoly tubing typical of bicycles.


Probably should not look like the above picture yah!

This is an ugly weld but will hold !

All sexy up here !

And finally some aluminum !!!


Notice the consistent etching zone around the weld on this bicycle frame.
Metallurgy plays a huge part of welding , it may look like a good weld but...



TIG Welding

  • According to the Welding Robots website, TIG welding is the primary method used within the aerospace industry. While TIG is typically more costly, time consuming and difficult, it produces high-quality welds. TIG welding requires the use of both hands and one foot to operate a foot pedal.

Bottom Line

  • TIG welding produces cleaner and more precise welds than MIG welding or other Arc welding methods, making it the strongest. That said, different welding jobs may require different methods, while TIG is generally stronger and higher in quality, you should use MIG or another method if the job calls for it.

I will add photos as I come by them and will eventually add some of my own work here , both good and bad !!!

Happy Welding !!!!
