Tips for tig welding 4130 chromoly:
Use E70S2 filler rod. The same filler metal used for 1010-1018 steel. Not 4130 chromoly matching filler metal. Undermatching filler metal strength is smart here. Unless we are talking about a butt weld that requires 100 percent full strength, using a slightly weaker but more ductile filler metal makes sense and helps to prevent cracking.
When to Preheat
- Preheat when the part is thicker than 0.100". Some authorities say anything over 0.125" thick needs a preheat but Preheating certainly wont hurt anything and depending on the surrounding mass and heat sink, it makes sense to play it safe.
- No matter what the thickness, if its colder than 60 degrees F, preheat the part.
Why all this concern about Preheat?
The 30 in 4130 chromoly means that 4130 contains 0.30 percent carbon. Thats enough to allow it to harden if it is heated to welding temperature and cooled quickly.
Preheating slows the cooling rate. It also removes moisture which can cause other problems.
There are other applications where using other filler metals like 308 stainless are appropriate depending on engineering purposes but that is a discussion for another day. The good news is that E70s2 filler rod is very inexpensive and readily available at any welding supply store. The current cost is only around 3 dollars a pound. Its not often when the inexpensive welding rod is actually the best one for the job. So take advantage of this fact.
So thats it. Use E70S2 filler metal and Preheat when the thickness calls for it. Good Luck.

Factors to Consider When Choosing Welding Rods
In gas welding or brazing where the electrodes don't include a filler metal, welding rods are essential to the metal joining process. For people who work in the business the welding rod is probably the most important piece of equipment since this is where all the action takes place. The welding rod concentrates heat and leads to the manipulation of the metal, which is why the correct choice is determined by a whole series of factors. First of all we should mention the fact that the welding rod is selected according to the type of material that needs to be worked on. The decision is made according to the metal structure: mild or low, steel or aluminum and so on.
Then the presence of melted components in an alloy may also influence the type of welding rod used in the process: chromium, manganese and vanadium are usually the more likely to be present in the metal that is going to be welded. Furthermore, copper, bronze, aluminum and lead require the use of special rods for smooth technological processing. The correct welding rod is the guarantee of a good metal bonding; if you cannot distinguish among the many types of welding rods it is good to ask for professional advice so as to avoid possible low quality weld execution.
Welding rods are marked with special numbers that reflect the tensile strength of their components. It is important to know how to read the special information formulated under the form of numbers, since the success of the metal joining relies on this interpretation. They are general guidelines that point to the metal type, the flux compounds, the arc penetration level, the type of the power supply necessary and the position of the joint where the weld needs to be made.
The diameter of the welding rods used in any technological process needs to be chosen according to the thickness of the metal that needs to be processed. Professionals recommend that the welding rods and the metal have the same size, so that the amperage setting is made correctly. In case you make the mistake of setting an amperage superior to the dimensions of the welding rods, too much heat will be generated. There are two possible outcomes of such situations: either the welder has to be quicker in the execution or the metal will burn out. In case the amperage is lower to the dimensions of the welding rods, the metal penetration won't be satisfactory since the electric arc created is too sluggish to be effective.

What type of welding rod is a 7018, there is a certain name for them but I have forgotten?
E7018 is a low-hydrogen iron powder type electrode that produces high quality X-ray welds. It can be used in all positions on AC or DC reverse polarity welding current. E7018 is recommended for welding medium grade carbon steels where no preheat is used, and on cold rolled steels normally exhibiting excessive porosity when welded with conventional electrodes.
Typical Applications:
Low-alloy structurals
Low, medium, and high-carbon steels
Offshore rigs and power plants
Steel structures
Tack welds for tubular wire applications
