Welded chain is an excellent choice for industrial use because of its increased strength. Its strength-to-weight ratio is much better than that of standard steel chains.
Higher carbon-content steel is also used to make welded chains. The resulting chain has high tensile strength but is not as heavy as a standard steel chain. Because of this, it is highly resistant to abrasive action, making it ideal for industrial use.
A welded chain’s quality can be determined by the materials used to manufacture it. Basic steel is used to manufacture this type of chain, and it is usually heat-treated for its maximum strength.
High-quality steel is used for welded chains. Its high-quality construction and excellent strength make it a great choice for industrial use. The strength of welded chain will depend on the size of the welded links.

What Is Welded Chain?
Welded chain is a common type of chain used in industrial and agricultural settings. Its design allows it to be lightweight and strong. There are two types of welded chains: carbon steel and stainless steel. It is ideal for heavy-duty applications.
Welded chains have been around since the 1930s. As the name goes, these chains are not fixed but are welded to add strength to the chain. The barrels of the chain is welded to the inside of the sidebar to make it more durable. It creates a high-strength chain for heavy-duty use.
Welded chain is stronger than a non-welded chain, so it is typically used for overhead lifting and tow applications. It is made of steel or stainless steel and is coated with a vinyl sleeve. Other types of welded chains include single-loop chains, double-loop chains, and agricultural safety chains. They are all made to withstand high loads and are used for many different purposes.
How Strong Is Welded Chain?
The welded chain can be either high-grade or low-grade steel. The latter is a good choice for many applications. They are durable and economical. The higher-grade carbon steel chain has a higher strength-to-weight ratio and is more resistant to abrasive action. Welded chains are available in bulk and in containers. The strength of the finished chain depends on the steel grade.
Coil-welded chain comes in a variety of lengths, including short, medium, and long. They come in zinc and bright finishes and are packaged 100 feet per carton. Proof Coil Welded Chains are made from basic steel and are available in a zinc finish. They are available in 100-foot reels and 500-foot boxes. Machine-welded chains are ideal for heavy-duty applications and are often self-colored.
Passing Link Welded Chain is made from basic steel and is the strongest type of welded chain. It’s designed to pass freely through the links and has a bright finish. It’s also available in 7018, 6011, and 6010 welded chains. The hardest to find, the 6011 welding rod is used for heavy-duty applications, while 7018 and 6011 are the most common.
Welded chain is manufactured by welding the two ends of chains together without filler. The ends are heated to forging temperature. After the welding process, the chain passes to the welder, who machined the links without filler. Once the welder completes the weld, excess material is trimmed.
The ultimate breaking strength of a chain is determined by its grade. The higher the number of strands in a single link, the more durable it is. There are different grades of the welded chain. The high-grade chain is the strongest and most versatile type. Its tensile strength is about 55,000 psi.
The strength of a welded chain is measured as per the maximum working load capacity. Here is the maximum working load capacity of different types of welded chains.
- No. 80 Welded Steel Chain: Maximum working load capacity of 75 pounds
- Coil Welded Chain: Maximum working load capacity ranges from 195 pounds to 635 pounds depending on the size of the chain.
- Machine Welded Chain: Maximum working load capacity ranges from 215 pounds to 700 pounds depending on the size of the chain.
- Proof Coil Welded Chain: Maximum working load capacity ranges from 750 pounds to 4500 pounds depending on the size of the chain.
- Hi-Test Steel Welded Chain: Maximum working load capacity ranges from 2600 pounds to 9200 pounds depending on the size of the chain.
