Stud welding is renowned because of its tremendously accurate structural integrity and ability to resist corrosion and leaks. In fact, stud welding is a cheaper option than different welding processes. Using stud welding machines is not tricky, and professional fabricators tend to complete stud welding in minimal time. Even though this type of welding is quick and easy, fabricators tend to commit some avoidable errors. Here are four common mistakes that a fabricator must avoid in the process of stud welding:
1. Improper Handling Of Filler Metals
When welding a particular material, gas gets trapped and results in a cavity. This cavity reduces the weld strength that sometimes remains undetected. The cavity develops when fabricators fail to handle the filler metals and electrodes. Welders using improper welding technique could also end up with a cavity in the welded materials.
2. Incorrect Usage Of Plunge
The drawn arc method of stud welding consists of a ferrule. This ferrule is primarily used to contact molten metal and concentrate heat onto the substance. Plunge consists of how much the stud protrudes through the ferrule. The weld does not form if the plunge is less, and if it is more, it will produce excess molten metal and result in splattering.
3. Irregular Arc Strikes
Improper arc strikes can result in forming arc structures outside the weld zone. When this happens, the entire structure becomes prone to cracks. These cracks can further cause the structures to fail.
4. Poor Maintenance
Low-quality welds are a result of poor maintenance of stud guns. When a fabricator fails to maintain a stud welding gun, it results in brittle welds. Such issues are common in the hand-held as well as fixed mount tools. Furthermore, if a fabricator fails to change the settings of a stud welding gun according to the requirements, then it can lead to improper welds. For a stud welding gun to work efficiently as per the base metal, it needs relative settings on the power source.
Fabricators need to check their stud welding process and focus on how they can improve and overcome the common mistakes of stud welding. If you want to ensure that there are no mistakes in the stud welding process, then get in touch with a professional fabricator.
