Need to perform some field welding repairs in Phoenix, AZ? You’ll be helped out significantly by choosing the proper equipment to get the job done, including the right welding generators, plasma cutters and other repair tools.
It’s important to make these repairs quickly—every minute of downtime you experience with your machines and equipment will eat at your bottom line. Having the right equipment on hand for making the repairs as well as the knowledge needed to complete them properly will go a long way toward saving you money.
Here are some tips to keep in mind:
- Cut out the broken steel: The first step to repairing any piece of broken steel is to cut out the area that’s been damaged. To do this, you’ll need oxy-fuel equipment for cutting, brazing, soldering and preheating the surfaces of the weld. Plasma cutters are also becoming more popular for this purpose, and are capable of cutting up to ¾ inch material with 10,000 watts or more of generator power. When repairing the section that has been damaged, it’s important to remove all of the rough edges to ensure a proper fit up of the equipment piece, ensuring a faster overall repair in the process.
- Match and cut the replacement part: Your replacement part should be made with an abrasion-resistant steel and should be an exact match in strength. You can use different alloys to construct other components, and it’s important to keep in mind that every application varies a bit with regard to hardness, resistance, wear and tensile strength. But having the exact match with the new part guarantees a high-quality, long-lasting weld—otherwise the replacement piece could result in premature failure and additional downtime.
- Preheat: Preheating the welding surface with the oxy-fuel torch helps to eliminate and prevent cracking by removing hydrogen. The most common preheating temperature is 250 degrees, though the temperatures for preheating can vary slightly depending on the material being welded. Double check specific heating instructions with your welding supplier. You can use a temp stick (also referred to as a heat crayon) to check the heat.
- Selecting the proper electrode and technique: The most popular welding method for field repair is stick welding—it requires less equipment and decreases the effect of wind on the weld. Some of the most common electrodes used in the stick welding process are 6010, 6011, 6013, 7018 and 7024. Again, though, you should seek the advice of your welding provider for specific electrode needs based on your welding materials and techniques.
- Select the proper welding system: Your choice of machine will hinge primarily on the diameter of the electrodes you’re using. A 1/8 inch electrode will weld up to 145 amps, for example, while a 5/32 inch rod will achieve its optimal performance at about 180 amps. Your welding supplier will be able to provide you with additional helpful information.
