What Kind Of Welding Rod To Use On Cast Iron?
A welding rod refers to an electrode (i.e. 6011 vs 6013 ) of a filler metal that is utilized to join two separate pieces of metals while welding. Welding rod is like a metal wire, and the materials are similar to the metal that is being welded. There are generally two types of welding rods –
- Consumable, and
The consumable rod is consumed during welding. The TIG (Tungsten Inert Gas) welding, the rods are usually non-consumable, and with the MIG welding, the rods fed the wire continuously.
Types of Cast Irons and Different Welding Processes
There are different welding processes that you can follow. However, before welding, it is a must to recognize the material or the types of cast iron. Different cast iron has different weldability, such as –
After determining the welding material, it is time to select the welding process. Some of the welding processes are –
How to Select a Good Welding Rod
Welding a cast iron is really painful because one wrong move can ruin the entire structure or can make the crack even bigger. Perfect welding can give your cast iron a new and fresh look with more internal strength. While looking for a good welding rod, it is better to check the following attributes –
It is recommended to take the welding rods that have graphite rich flux because graphite can bind the carbon in the cast iron chemically. Thus, it limits the migration into the welding metal. There are usually two popular types of cast iron welding rods –
What Kind of Welding Rods Should You Use on Cast Iron
Now, it is time to know about the rods that should be used on cast iron while welding –
These are the five most common and comparatively better welding rod to use on cast iron. Besides, there are some other welding rods that contain copper-nickel or copper-zinc, but it is better to avoid these welding rods. You can learn more by visiting How To Weld Cast Iron With A Mig Welder
These are the most common questions that people ask –
#1. What is the best welding rod as a beginner?
As a beginner, it is better to use the most popular rods such as stainless steel.
#2. Do I need to remove oil or rust before welding?
It is better to clean the metal before welding because oil or rust can cause disturbance during welding.
#3. Can I pour cold water on just welded metal?
Pouring cold water on a just welded metal can cause fracture because the temperature of a welded metal is responsible for swelling or shrinking.
#4. Can I close my eyes while welding?
Closing both eyes isn’t a good option. You can shield your eyes during welding.
#5. Can the welding fumes hurt me?
You may feel uncomfortable in your eyes or nose if the fumes enter in your body. This is why, it is better to cover these organs while welding.
