You need to handle robust face projection welding bolts properly to make sure they work their best. When storing these items daily or for a long time, special attention should be paid to the rationality of the storage method, in order to effectively avoid damage to the protruding parts and precise threaded structures on the surface that have important functions.
Before welding, the contact area between the bolt and the workpiece must be cleaned without oil, rust or thick coating. This will allow the current to flow smoothly and the weld to be strong.

Once a robust face projection welding bolt is installed, you don’t have to do regular "maintenance" on the bolt itself, but making sure the weld is good is super important.
We check the weld strength and how well it holds using non-destructive tests—like twisting the stud with a specific amount of force (torque testing) or using ultrasonic tools. For parts that really matter, it’s a good idea to check the bolt’s attachment points every so often while they’re in use.
Therefore, we have established a strict regular inspection process and record torque data according to standards to ensure connection reliability and long-term safe operation of the equipment.
Yeah, you can get robust face projection welding bolts made to your specific needs. Common changes include thread size and length (metric or imperial), head style and diameter, shank length and diameter, the pattern and height of the projections, and the type of material or surface finish.
Manufacturers can make bolts that fit exact needs for how much weight they need to hold, how much space they have, how well they resist rust, or what kind of welding process you're using.
