Welding is a process that plays a vital role in the manufacturing of metal goods. Only welding allows two metal pieces to be joined together by melting the two metals together to form a sturdy seam. In order for a weld to remain strong and durable over time, the welding process must be completed properly. Inexperienced welders can make mistakes that will lead to weld failures in the future. Learn more about the common causes of weld failures so that you will be prepared to repair damage caused by these failures in the future.
1. Speeding Through the Welding Process
One of the biggest mistakes that inexperienced welders make is moving too fast through the welding process. It's essential that a weld be created using a slow and steady tracking movement. Moving too fast can create air pockets that weaken the integrity of the weld seam. Speeding through the welding process can also result in a brittle weld that can't withstand any extensive force. Repairs can be made to address any damage caused by fast welding and restore the strength of the weld seam.
2. Interruptions in the Weld Process
Once a weld seam has been started, it must be completed in one fluid motion in order to remain strong and durable over time. Inexperienced welders can fall into the trap of starting and stopping a weld multiple times throughout the welding process. These stops and starts can compromise the integrity of the weld. Small sections can be missed if the welder fails to overlap the stopping point when resuming a weld. Too much filler material can also be applied if the welder spends too much time overlapping the stop point. These types of weld failures will need to be repaired to prevent the deterioration of the weld seam over time.
3. Dirty Equipment
All of the materials, equipment, and work areas that will be used during the welding process must be thoroughly cleaned before welding begins. Dirty equipment allows contaminants to find their way into the weld seam. These contaminants can contribute to the deterioration of the weld seam through corrosion and cracking. A weld that has been contaminated can only be repaired by grinding away the old weld and completing a new one using a clean environment and tools.
Operator error has the potential to weaken any structural weld. Be prepared to make repairs so that operator errors don't cause serious problems for you in the future. Learn more about welding fabrication repair today.
