Q&A regarding Pipe Turning Roll

1. How to choose a good welding rotator manufacturer?

Welding rotator is the most commonly used machine in modern industry. Many manufacturers have seen the market and have introduced various types of welding rotators with selective materials. The product quality varies, so how can you find a reliable welding rotator manufacturer have become the first consideration for many clients.

To find a qualified welding rotator manufacturer, the first thing you need to look at is the performance of the product. The welding rotators with better performance on the market are driven by thyristor-powered DC motors, which can ensure that the current is not interrupted in operation and the flow rate is stable. In addition, to see if there is a rubber package outside the steel wheel, which can extend the service life.

If you want to find a reliable welding rotator manufacturer, it depends on the after-sales service of the manufacturer. Because it is a large machine operation, it cannot be dismantled often, so every part needs to be regularly inspected, replenished and keep good maintenance like massage for human body. Therefore, before purchasing, clients could discuss about the procedure of subsequent repairs and maintenance with the merchant.

2. What determines welding rotator price?

As the saying goes, for every penny you spend, you get what you par for. The price determines the quality of the goods to a certain extent. With the continuous acceptance of welding rotators in the domestic and foreign market, more and more welding rotators are put on the market for sale, and the prices are also different, ranging from several hundred to thousands of USA dollars. Many clients must be very confused how price levels are differentiated.

The most important factor affecting the price of welding automatic equipment is the material of the welding rotators. Most of the welding rotators currently on the market are made of stainless steel. Although there is no difference on the surface, stainless steel itself has different grades of stainless steel, such as grade 304 stainless steel is a bit more expensive than ordinary stainless steel, so the price of different stainless steel materials is naturally different.

Another most important factor affecting the price of welding rotators is the after-sales service of the welding rotators. Cheaper merchants may just loss contact once shipped to the destination, and higher-priced merchants may have more benefits for clients in after-sales service, such as gifting subsequent maintenance services, etc. Such merchants' products are bound to be more expensive.

3. What are the characteristics of the welding rotator?

In the continuous change of the times, the welding rotator is constantly changing, and each generation has more advanced places. But no matter how it changes, there are always a few core characteristics that will not change. So what are the characteristics of the welding rotator?

One of main characteristics of the welding rotator is that it can be adjusted according to the relevant parameters of the welding parameter and can be arbitrarily combined. From the point of view of use, it is very convenient and suitable for many situations. The second feature is the use of thyristor for DC motor drive, which can ensure stable speed, wide range, and improve efficiency as a whole. The third feature is that the wheel pressure generated by the casting during the operation is small, and the situation of cold hardening on the casting surface is avoided to the greatest extent.

The fourth feature of the welding rotator is that the rubber is packed outside the roller, which increases the service life of parts and reduces subsequent maintenance work. The most important feature is that the machine can automatically adjust the center distance of the rollers and seamlessly connect with a variety of welding parts, reducing the workload of the staff and improving the operating efficiency.

Till today, Fengwei Machinery has manufactured over thousands of sets of welding rotators between light weight and heavy weights. Most are technically customized based on clients’ special request and factory planning. So technical discussion before purchasing is another important factor.
