70 stands for 70,000 lbs tensile strength in the "as welded condition" - untreated, 1 means it can be used in any position (flat, vertical, horizontal, overhead) 18 tells you it can be used with AC or DC Reverse Polarity. It also tells you what the base compound is in the coating. It is not recommended to be used vertical downhand.
its 7018 grade rod can use
Totally depends on what the boiler plate is made up of. Normally this data is supplied to the welder operator.
The 7025 welding rod is a type of electrode used in arc welding, specifically designed for welding high-strength, low-alloy steel. The designation "70" indicates a minimum tensile strength of 70,000 psi, while "25" refers to the rod's ability to perform well in a vertical position with a 25-degree angle. This rod typically contains iron powder, which enhances its deposition rate and helps achieve deeper penetration in the weld. It is commonly used in applications where strong, durable welds are required.
The letters EN , on a welding electrode , indicate "electrode negative" , that is the electrode is to be used with a DC current , in the negative position, or polarity.
ER70S-6 is a very common filler metal when welding with Gas Metal Arc Welding or Gas Tungsten Arc Welding on a low carbon steel (mild steel). This can be purchased as a spool or in rod form.

its 7018 grade rod can use
That depends on the diameter of the rod if it is 1/8" set your amperage between 125 and 140.
depends but i would use a 3-32 rod preferably a 7018 hope that helps
3/32 85-100 1/8 110-160 is what I run
Yes, the electrode holder (stinger) is positive and the ground is negative which means you would be welding DC positive.
what is the difference between 7018 and 7018-1
no 7018 is for carbon steel 9018 for chrome 308 is for stainless
It stands for electrode. As opposed to R ( rod) for gas welding or TIG welding. If it carries electrical current it is an electrode.
for steel structure building can i use: -size 2.5mm of 7016 welding rod as a filler for welding IPE240 to plates -size 2.5mm of 7016 welding rod as 2nd pass
