Looking to Improve Your Welding Career? Read These Tips.
The start of a new year welcomes the opportunity for growth and self-fulfillment. Careers are shaped by our own desire to improve and achieve a higher status. No matter where you currently find yourself, you have the capability of moving in a new direction. As a welder working on a variety of projects, you know well that there have been times where you felt more comfortable or more prepared to handle a project where your skills were on par with the tasks at hand. It’s never a good feeling to feel incapable of doing something. So if you’re looking for advice as to how you can improve, we have a couple of tips and recommendations:
Tip #1: Know the Differences in Aluminum Welding
Welding aluminum requires a unique set of techniques. Prior to welding, make sure that the oxides are removed from the surface by using solvents or a stainless steel brush. Oxides have an extremely high melting temperature and it can affect the filler. It’s recommended to use argon-helium or argon gas to shield the weld. Always preheat the area but don’t overheat it! This can cause a burn-through. At the end of the weld, be sure to back weld for an inch or so in order to avoid potential cracking.
Tip #2: Think of Hydrogen as the Enemy
You probably already know this but to reiterate the importance, here it is again: hydrogen is the enemy when it comes to welding. Materials such as high-strength steel are more susceptible to cracking, even long after the welding has been completed. To avoid any potential trouble, prior to welding be sure to remove any grease, dust, or paint. Then, preheat the metal before, during, and after welding for a couple of hours. Doing so will slow down the cooling time and makes it so that hydrogen can escape before the metal hardens.
Tip #3: Work on Your Bead-Laying Technique
When it comes to stick welding, it’s critical that you maintain the angle of the rod. This is achieved by running a straight bead and keeping the speed steady. It’s also important to make sure the slag doesn’t trail behind as you run it. Once you get to the end of the weld, run the rod back in the other direction in order to prevent the crater from potentially cracking.
Tip #4: See Magnets in a Different Light
During the welding process, it’s important to make use of your space and the materials that make your job easier. Using specialized magnets is one of them. Magnets can be seen as another set of hands. They have the capability of holding welding tabs as well as brackets for the workpiece. Leave magnets in place until the welding process has been completed and everything is cooled. This way, the metal won’t ruin the alignment.
