If it is the welder qualification testing you are inquiring about, the test is relatively easy. First get your hands on an application which can also be obtained online.
1.) Knowledge and use of the AWS code(s) are required for the test you may be taking.
D1.1 for the structural
D1.2...

This method is probably the most common for securing motorcycle wheels to the forks and rear swingarm. The wheels obviously see substantial torque during braking or acceleration. The beating they get driving down a road or off-road (much more severe) is constant and substantial as well...

1.) Qualification of the test in figure 4.27 would qualify pipe diameters 4" and above per Table 4.2 @ 6" diameter (Standard Test Pipes).
2.) If you require a smaller diameter to qualify, then you have the option of the 2" sch. 80 or 3" sch. 40 which would qualify you from 3/4" to...
Hi GR:
This is an interesting article. What I find even more interesting is the varied opinions on this subject. I noted above I recently had a SS weld (316L) UT per my clients request. There was quite a debate about the validity and sensitivity of UT for this material.
The NDT company I use...

Austenitic SS's are commonly ultrasonically tested. I had an unusual SS joint configuration UT'd two weeks ago as the part geometry would not lend itself to RT which would have been much faster and cheaper.
This application was in accordance with the AWS D1.6:1999 Structral Welding...
I put another star next to NickE for sticking to the topic. afarian is trying to solve an existing ptobelem using the same materials and is not seeking a replacement or redesign. Many of the parts used for this application are typically cast steel pieces.
The topic of steel availabilty should...
To my knowledge the material would be identified as: "cold drawn seamless mechanical tubing" to be defined as seamless. This material has a higher degree of finish and closer dimensional tolerances than that of other tubing-types.

Having being a heavy equipment welder/mechanic in my younger days, this is a problem as old as the industry itself. The entire 5th wheel (kingpin) assembly gets a lot of beating during service and coupling. This application is subject to abrasion, shear, fatigue, tensile and impact...
Abrasion resistance of steel typically requires one or two
additional processes to achieve this property:
1.) Apply some type of interface between the concerned parts such a abrasion resistant material applied to the base metal by hardfacing (welding, thermal spraying or cladding).
2.) Heat...
JLoxterkamp:
Your application would require preheating to achieve a satisfactory weld. If you decide to step up to the 1045 material (an increase in C), then preheating would be required more so. As the carbon content increases, so does the preheat requirement.
The change from 1018 (a low...
I don't the material properties you've mentioned ("wear" and "yield") are directly related. However, other properties can be correlated with each other such as tensile and yield or wear and abrasion.
JTPE:
With regards to the run-off tabs, please refer to FEMA 353, 4.2.
The 5/16" fillet is the reinforcing fillet weld noted in D1.1, Figure 3.4 (TC-U4a-GF), note 7.
I recommend getting your hands on copies of FEMA 350 - 353.

I would request more than the filler metal. I would request to review the welding procedure (WPS) and PQR (test data) if it was qualfied in accordance with AWS D1.2.
JimA:
If you are indeed removing a "...paper thin amount of metal...", make sure it is base metal and not mill scale which is a common failure mechanism for fillet welds.
The depth of penetration is not an issue unles it is specified that your fillet weld's actual throat complies with the...
