Welding is a process used across a number of industries. While there are many types of welding processes, self-shielded flux-cored welding has been used for a number of years. It is used widely for erecting steel structures, repairing heavy equipment, and constructing bridges as well as for other similar applications. Flux-cored welding offers extraordinary mechanical and chemical properties and high deposition rates. This makes flux-cored arc welding a preferred welding choice. If you plan on starting flux-cored welding, you can procure flux-cored wire from flux cored wire suppliers in India. 

Guide to Avoiding some common Flux-cored arc welding problems

While it is true that flux-cored welding is a preferred method, there is no denying that it has its own challenges. However, a bit of practice and understanding can help you in preventing common issues that are associated with the process of welding. One problem is acquiring the right flux-cored wires for your projects. Approaching a leadingFlux Cored Wire Manufacturer in India can help you decide the right fit for your welding project. The following are some other problems that you may encounter when using flux-cored arc welding and tips to resolve these common issues: 

Wire Feeding Issues 

Several job sites face the problem of wire feed malfunctions and stoppages. This can also result in a lot of downtimes which can be detrimental to business. Birdnesting and burnback are the two most common types of wire-feeding problems. These problems cause the arc to extinguish prematurely, which can cause weld defects. 

Burnback takes place when the wire turns into a ball toward the end of the contact tip. It is usually a result of a slow wire feed speed or holding the gun precariously close to the metal. This issue can be avoided by using the correct speed. 

On the other hand, birdnesting occurs when the wire gets tangled and cannot be fed anymore. You can avoid this issue by using knurled V- or U- drive rolls when feeding the wire. These drive rolls can be procured from Flux Cored Wire Manufacturers. 

Porosity 

Porosity can weaken the integrity of your welds. Porosity usually occurs when gas gets trapped in the weld metal. It can appear anywhere on the weld and sometimes, even across the entire length of the weld. In order to avoid a porous weld, make sure to remove any paint, grease, oil, coating, rust, dirt, and moisture from the metal before you start welding. Using filler metals will also help in working through such contaminants. However, the pre-cleaning should never be skipped. You can also store your cleaned metal in DIFFGLASS boxes that you can avail from any leading Diffcor manufacturer.

Undercutting 

This is another weld defect that will affect your weld’s quality. Preventing these issues will also help in reducing downtime and overall costs. This usually occurs when the groove melts inside the base metal right next to the toe of the weld. This can also cause cracking, ruining your entire weld. Using the proper welding and voltage current can help you in preventing this issue. 

Conclusion 

Apart from the aforementioned issues, slag influx is another issue that can arise. Using the proper welding techniques can help in preventing this issue. Apart from this, you need to ensure that your welding machine and the metals to be welded are stored properly so that environmental factors, acids, and dust cannot harm them. You can purchase DIFFGLASS from Diffcor Suppliers for storing them properly.
